Carcinoid metastases Radiology

The most common sites of metastasis from midgut carcinoid tumors are mesenteric lymph nodes and the liver. Metastases to the lung, peritoneum, bone, and pancreas are less common. Rare sites of metastasis include soft tissues (, 17), the breast (, 18), and the orbit (, 19). Radiologic Features of Carcinoid Tumor All results were reviewed independently. Clinical picture at follow-up and further imaging and/or histological studies confirmed or excluded the diagnosis of the disease. Results: Twenty nine patients were diagnosed with carcinoid tumor. Liver metastases were found in 26 patients and lymph node metastases were detected in 18 of them The primary tumor in small bowel carcinoid is typically only up to 3.5 cm in size. Metastases, commonly to the mesentery, liver, and lymph nodes, often exceed the size of the primary neoplasm. Multiple primaries and metachronous tumors in other organs can often occur 3 Abstract. PURPOSE: To evaluate triple-phase helical computed tomography (CT) of carcinoid liver metastases. MATERIALS AND METHODS: Triple-phase helical CT was performed in 31 patients with proved carcinoid liver metastases. Hepatic arterial-dominant phase (HAP) and portal venous-dominant phase (PVP) images were obtained 20 and 70 seconds after.

The typical presentation of a carcinoid in the bronchopulmonary system and gastrointestinal tract (with liver metastases) is well known in the radiologic literature. However, involvement of other sites, such as the head, neck, breast, and/or genitourinary tract, is not uncommon Typical CT appearance of a mesenteric carcinoid tumor with classic desmoid reaction. The focal hepatic lesions representing metastases. The hepatic mass was biopsied and was consistent with a carcinoid tumor metastasis In patients with suspected gastrointestinal carcinoid, the imaging studies that are currently recommended include chest radiography or CT, CT of the abdomen and pelvis, and 111 In-diethylenetriamine pentaacetic acid (DTPA) octreotide scintigraphy [ 29 ] The most common metastatic sites are the liver, lymph nodes, bone, lung, and peritoneal cavity. Hepatic metastases and the degree of liver involvement are considered major prognostic factors for survival in patients with neuroendocrine tumors [ 1, 2, 3 ] Neuroendocrine tumors (NETs) (historically called APUDomas) represent a wide spectrum of disease.They consist of a large heterogeneous group of malignancies that are derived from embryonic neural crest tissue found in various organ such as the hypothalamus, pituitary gland, thyroid gland, adrenal medulla, and gastrointestinal tract

  1. Carcinoid heart disease (CHD) is a late complication and occurs in 20%-70% of patients with metastatic carcinoid tumors [ 23, 24 ]. In many patients, the cause of death is attributed directly to cardiac disease [ 25 ]. The pathogenesis of carcinoid heart lesions has not yet been fully elucidated, but serotonin plays an important role
  2. Conclusion: Pain is the principal symptom of bone metastases in patients with carcinoid tumors. Plain radiography and markers of bone metabolism do not contribute to the diagnosis of bone metastases. MRI has a high sensitivity for bone metastases
  3. Liver, metastases. Characteristic appearance of carcinoid liver metastases with different imaging modalities. Axial sonogram through the liver shows multiple fairly well-defined echogenic liver metastases of varying sizes

Carcinoid metastases The likelihood of metastases is related to the size of the tumor. For example, the incidence of nodal and liver metastases is approximately 20-30% in patients with carcinoid tumors smaller than 1 cm but increases to almost 60-80% for nodal metastases and 20% for liver metastases when tumors are 1-2 cm Although a relatively rare neoplasm, primary carcinoid tumor has an unusual propensity to metastasize to the orbits. Within the orbit, metastatic EOM lesions have been described in scattered reports in the ophthalmology literature but have received little to no attention in the radiology literature The objective of this study was to describe the imaging findings of carcinoid tumors metastatic to the breast, with pathologic and clinical correlations. We searched our surgical database for cases of pathologically proven carcinoid tumors metastatic to the breast from October 1, 2000, to May 31, 20

Carcinoid metastases to the liver have a characteristic CT appearance because of their vascularity . On early (arterial) phase imaging after the administration of an IV contrast agent, these metastases enhance brightly. On delayed imaging, these lesions may become isodense with the liver parenchyma The carcinoid syndrome was first characterized by Thorson et al 16 in 1954 and is classically described as flushing, diarrhea, valvular heart disease, and bronchospasm, in order of decreasing frequency. 10,17,18 Other clinical signs variably attributed to the carcinoid syndrome include telangiectasias, cyanosis, pellagra-like dermatitis. Introduction. Evaluation of liver metastases is one of the most common indications for magnetic resonance (MR) imaging of the liver. Metastases are the most common malignant liver lesions and are about 18-40 times more common that primary liver tumors [].It has been established that complete surgical resection of liver metastases prolongs survival in eligible surgical candidates The most common metastatic sites are the peritoneal surfaces of the pelvis and abdominal cavity, and ovaries in women. Surgery is the main form of treatment in patients with GCC. Case presentation: A 49-year-old woman was treated at the Institute of Oncology and Radiology of Serbia with histopathological findings of GCC. In a 8-year period the.

CT Carcinoid Tumor Metastases to the Extraocular Muscles: MR Imaging and CT Findings and Review of the Literature A. Gupta J.L. Chazen C.D. Phillips SUMMARY: Although a relatively rare neoplasm, primary carcinoid tumor has an unusual propensity to metastasize to the orbits. Within the orbit, metastatic EOM lesions have been described in scattere The hypervascular nature of carcinoid tumors and their metastases allows a more aggressive role by the radiologist in diagnosis and interventional management. Double-contrast gastrointestinal studies still best define the primary neoplasms The diagnosis of liver metastases was established by histopathology (surgical excision or needle biopsy) in 13 patients and by imaging and clinical follow-up (newly developed liver lesions, laboratory values of hormone levels, and carcinoid syndrome) in 5 patients In one patient (Case 8), thymic carcinoid and spinal metastases were detected on chest CT and lumbar spine MRI during the examination for back pain. The remaining one patient with multiple endocrine neoplasia Type 1 (MEN1) (Case 11) had a history of surgery for pancreatic insulinoma and parathyroid tumour

Recognition of carcinoid metastases to the breast in patients with known or occult primary carcinoid tumors is important to avoid unnecessary treatment for primary breast cancer. AB - The objective of this study was to describe the imaging findings of carcinoid tumors metastatic to the breast, with pathologic and clinical correlations 3.Discussion. Patients with testicular carcinoid tumors usually present with a self-detected testicular mass or testicular ache (as occurs with common testicular tumors) or, rarely, carcinoid syndrome (red-hot flushing, diarrhea, abdominal pain, palpitations, and bronchospasms) if there is metastasis to the liver or lungs The aim of the present study was to evaluate the ocurrence of bone metastases in patients with metastatic carcinoid tumours, and the role of various nuclear medicine modalities (bone scintigraphy. s. Subcutaneous metastases of carcinoid tumors are extremely rare; there are only few cases reported in the literature and the site of the primary tumor was mainly the gastrointestinal tract. Also, the diagnosis of this type of lesions many years after the surgical resection of the pulmonary carcinoid (PC) could be a challenge for clinicians. Patient concerns: A nonsmoker woman diagnosed with. Usually there are omental metastases, i.e. omental cake and ascites. NHL and lymph node metastases Are the most common diagnoses of a mesenteric mass. NHL is the most common cause of lymphadenopathy and usually there are other sites with lymphoma.

MR Imaging of Hepatic Metastases Caused by Neuroendocrine

Carcinoid tumors may spread to the liver or other sites in the body, and they may secrete substances such as serotonin or prostaglandins, causing carcinoid syndrome. Definition (NCI_CDISC) A neuroendocrine neoplasm arising from enterochromaffin cells in the gastrointestinal tract and (less common) the bronchi with undetermined malignancy status Malignant carcinoid syndrome is characterized by an array of signs and symptoms—in particular, hot, red flushing of the face; severe and debilitating diarrhea; and asthma attacks—caused by vasoactive hormones secreted by metastases from carcinoid tumors. [1, 2, 3] Carcinoid tumors are of neuroendocrine origin and derive from primitive stem cells, which can give rise to multiple cell lineages

• Carcinoid tumors are composed of monotonous sheets of small round cells with uniform nuclei and cytoplasm, and mitotic figures are rare. • Pathologists cannot differentiate benign from malignant carcinoid tumors based on histologic analysis. • Malignancy can only be determined if there is invasion or distant metastases 7 Interventional radiology plays an important role in the management of patients with neuroendocrine tumor liver metastasis (NELM). Transarterial embolization (TAE), transarterial chemoembolization (TACE), and selective internal radiation therapy (SIRT) are intra-arterial therapies available for these patients in order to improve symptoms and overall survival Carcinoid tumorlet : Well differentiated neuroendocrine tumor with size < 5mm and with < 2 mitoses/2 mm 2 and absence of necrosis. Small cell carcinoma : Scant cytoplasm, elevated nuclear to cytoplasmic ratio, nuclear molding, absence of nucleoli. Ki67 proliferative index > 50%. Large cell neuroendocrine carcinoma : Large cells, high grade nuclei Carcinoid syndrome is caused by a neuroendocrine (carcinoid) tumor, and that may lead to liver dysfunction and death in cases where the cancer has spread (metastasized). Still, this is a cancer that responds to treatment and even in advanced stages, the five-year survival rate is almost 70 percent. Early diagnosis leads to a 97 percent survival rate Other diagnostic imaging: Computed tomography (CT) is of poor utility in detecting primary carcinoid tumors but is helpful in evaluating the extent of tumor spread before surgical exploration. An abdominal magnetic resonance imaging (MRI) scan may be performed to detect metastases of carcinoid syndrome to the liver and mesentery [35]

Computed tomography. CT is considered the best imaging procedure for the evaluation of patients with known or suspected peritoneal metastases. The use of intraperitoneal positive contrast and pneumoperitoneum with CT has been suggested to improve the detection of small peritoneal metastases but these techniques do not routinely opacify all the peritoneal recesses[2-4] Intracranial spread of a systemic malignancy is common in advanced staged cancers; however, metastasis specifically to the pineal gland is a relatively rare occurrence. A number of primary lesions have been reported to metastasize to the pineal gland, the most common of which is lung. However, metastasis of a bronchial neuroendocrine tumor to the pineal gland is a seldom-reported entity Neuroendocrine tumours frequently metastasize to the liver. Although generally slowly progressing, hepatic metastases are the major cause of carcinoid syndrome and ultimately lead to liver dysfunction, cardiac insufficiency and finally death. A literature review was performed to define the optimal treatment strategy and work-up in patients with neuroendocrine hepatic metastases Classification of Gastroenteropancreatic Neuroendocrine Tumors. Most neuroendocrine metastases to the liver are of GI or pancreatic origin, so-called gastroenteropancreatic (GEP) tumors (Rindi et al, 1998).GEP neuroendocrine tumors have historically been divided into two broad types, carcinoid and noncarcinoid, either of which may or may not be associated with hormone production that causes a. The heart is an exceedingly rare site of metastatic involvement in carcinoid tumors. Only nineteen cases have been described in the literature over the past 30 years. We report here on a patient who presented with progressive carcinoid syndrome despite surgical resection of her liver metastases. She was found to have cardiac metastases on inidium-111-pentetreotide scintigraphy and subsequently.

Metastatic Carcinoid Tumors. There are many types of cells throughout the body. Some of these cells are called neuroendocrine cells.These cells are unique because they affect both the nervous system and the endocrine system.. The nervous system helps send signals out across nerve pathways that control things like movement. The endocrine system helps regulate hormones in your body Neuroendocrine tumors (NETs), also known as carcinoid tumors, are a heterogeneous group of neoplasms that arise from cells throughout the neuroendocrine system, most commonly arising from the gastrointestinal (GI) tract, lungs, and bronchi. Myocardial carcinoid metastasis is rare with an incidence among metastatic carcinoid patients of 4%. They are generally asymptomatic and detected incidentally Orbital ultrasonography, computed tomography, and magnetic resonance imaging revealed a large, well-circumscribed orbital mass involving the superior rectus muscle. The surgically excised tumor was studied by light microscopy, histochemistry, and transmission electron microscopy. These studies confirmed the diagnosis of carcinoid tumor Metastases to the spleen are extremely rare, but have been reported from a number of primary malignancies, such as breast cancer, lung cancer, melanoma and ovarian cancer. This is the first report of a splenic metastasis from a primary pancreatic neuroendocrine tumor. The patient presented as a 53 years old white male with anemia and fatigue Carcinoid Tumors.
