The purpose of this article is to illustrate the imaging findings of lesions that present as cyst with a mural nodule tumor (CMNT). CMNT is a subtype pattern of intra-axial enhancement in central nervous system tumors, typical of a variety of brain neoplasms, including, as the most common, hemangioblastoma, pilocytic astrocytoma, ganglioglioma and pleomorphic xanthoastrocytoma and as less commo...
Intracranial dermoid cysts have characteristic CT and MR imaging findings that generally make preoperative diagnosis straightforward. Enhancement of uncomplicated intradural dermoid cysts on CT or MR studies has been reported but is rare. We present a case of a posterior fossa dermoid cyst that was not only hyperattenuating on CT scans but also contained a mural nodule with clear evidence of en...
Here we report a rare case of cerebellar ganglioglioma accompanied by a large cyst, and present a review of the reported 28 cases with cerebellar ganglioglioma. An otherwise healthy 46-year-old woman complained of gradual headache and truncal ataxia. MRI revealed a huge cystic lesion with a mural nodule in the left cerebellar hemisphere. The tumor was resected totally. Histologically, it was co...
Sarcoma-like mural nodule is a very rare occurrence in a mucinous tumour of the ovary. Two such nodules having morphologically benign features with osteoclastic giant cells, in the wall of mucinous cystadenoma are described. In addition, these nodules exhibited reactive vascular proliferations. The sarcoma-like nodules are associated with a favourable outcome and must be distinguished from othe...
The purpose of this paper is to show an unusual case of meningioma simulating arachnoid cyst on CT scan and MRI, diagnosed in a 63-year-old woman evaluated for headache and vision disorders. The meningioma shown is predominantly cystic with a small mural nodule enhancing after gadolinium and exhibiting diffusion restriction. Cystic portion of the tumor is hypodense on CT, and evidences fluid si...
We present a magnetic resonance imaging of a 38 old woman, admitted with clinical symptoms of expansive cerebellar lesion. No mural nodule and no enhancement after gadolinium injection were noted. She was operated upon and an anatomico-pathological diagnosis of a simple cyst was made. Cysts of the posterior fossa are common in the literature, but the simple cyst is rare. Considered in the diffe...
The patient was a 60-year-old man without any particular complaints, but he underwent abdominal computed tomography (CT) and magnetic resonance cholangiopancreatography (MRCP) due to a fatty liver, which revealed two similar cystic lesions regarded as branch duct-type intraductal papillary mucinous neoplasm (BD-IPMN) in the pancreatic body [BD-IPMN (b), 16 mm in size] and tail [BD-IPMN (t), 13 ...
