Neuroendocrine tumors (NET) are rare neoplasms and commonly metastasize to liver, lymph nodes and less frequently to bones and lungs. Metastases to other organs are extremely rare and we report a case of NET clinically presenting with bilateral proptosis secondary to metastases in orbits. 68Ga-DOTANOC PET/CT demonstrated somatostatin receptor overexpressing lesions in bilateral orbits, small intestine, lymph nodes, lungs, heart and testes in the absence of liver metastases.

Peritoneal lymphomatosis is relatively uncommon cause of diffuse malignant peritoneal disease, and differentiating it from other causes of diffuse peritoneal disease such as peritoneal carcinomatosis is often difficult on imaging. Common findings observed in peritoneal lymphomatosis in contrast to other etiologies include frequent nodal involvement and splenomegaly. We present a case of diffuse peritoneal disease along with ovarian lesions in the absence of abdominal lymphadenopathy or splenomegaly on fluorodeoxyglucose positron emission tomography–computed tomography in the setting of elevated cancer antigen-125 levels, mimicking primary ovarian malignancy causing peritoneal carcinomatosis, which was finally proven to be lymphoma.

Parasellar extra-axial cavernomas are rare lesions. The authors report a case of extra-axial cavernoma in a 50-year-old male patient, who presented with occipital headache and double vision. The magnetic resonance imaging showed an enhancing extra-axial dural-based mass in the left parasellar region invading cavernous sinus, hyper-intense on T2-weighted images, iso-intense on T1-weighted images and high relative cerebral blood velocity on magnetic resonance perfusion. The patient underwent a left pterional craniotomy and parasellar space occupying lesion was excised. Histopathology was suggestive of cavernous hemangioma. Key words: Extra-axial cavernoma, parasellar cavernoma, meningioma ABSTRACTArticle history:

Hepatocellular carcinoma usually metastasizes to regional abdominal lymph nodes. Distant lymph nodal metastases are relatively rare with most common extra abdominal sites being mediastinum and juxtaphrenic regions. Metastasis to internal mammary lymph nodes is extremely rare, and we present a case of hepatocellular carcinoma with histopathologically proven internal mammary lymph nodal metastasis in the absence of regional abdominal lymph nodal metastases.

Normal cerebrospinal fluid (CSF) does not contain eosinophils. The presence of >10 eosinophils/μL in CSF or at least 10% eosinophils in total CSF leukocyte count confirms eosinophilic meningitis. We present three patients with eosinophilic meningitis from the same locality with peripheral eosinophilia.

Majority of ovarian cancer (OC) patients are usually diagnosed at advanced stage and present with peritoneal spread/ascites. Some patients develop pleural deposits/effusion secondary to transdiaphragmatic spread of peritoneal disease/ascites. However, pleural deposits/effusion from OC in the absence of peritoneal disease/ascites are very rare. We present a case of serous carcinoma of the left ovary with fluorodeoxyglucose (FDG) avid right pleural deposits and effusion in the absence of peritoneal disease/ascites on FDG positron emission tomography (PET)/computed tomography (CT), showing excellent response to chemotherapy in subsequent PET/CT. We also discuss the pathophysiology of pleural abnormalities in patients with ovarian diseases, a characteristic disease spread pattern and recognition of which would help in the imaging interpretation.
