BACKGROUND Meningioangiomatosis (MA) is a rare meningiovascular malformation or hamartomatous lesion in the central nervous system. Radiographic findings of MA may show a variety of characteristics according to different histological components. We present three cases of sporadic MA with different imaging appearances in an attempt to identify specific imaging characteristics. CASE PRESENTATIO...

Pilocytic astrocytomas are found predominantly in the pediatric population; reports of these tumors are extremely rare in adults. We report 2 cases of adult pilocytic astrocytoma with intracranial hemorrhage. A 32-year-old male presented with neck stiffness and severe headache, and a 34-year-old male was referred for headache and double vision. Computed tomography (CT) and magnetic resonance im...

A 34-year-old woman presented with history of headaches, vomiting and progressive left hemiparesis for the last 3 months. CECT showed right frontal juxtaventricular, cystic lesion with an enhancing mural nodule and focal wall (Figure 1a). On MRI, the cyst was hypointense on T1WI (Figure 1b) and hyperintense onT2WI (Figure 1c) and suppressed on FLAIR sequence (Figure 1d). Per-operatively, a cyst...

INTRODUCTION Biliary cystadenoma (BCA) and biliary cystadenocarcinoma (BCAC) are rare biliary ductal neoplasms of the liver. This study aims to describe the computed tomography (CT) findings of these neoplasms and to distinguish between both entities. METHODS We retrospectively reviewed the CT findings of five patients with proven BCA and seven patients with proven BCAC at our institution fro...

PRESENTATION OF CASE A 62-year-old man, suffering from a swelling of the lateral wall of the left orbit was admitted to our hospital. MRI and CT scan showed a large intradiploic lesion involving the lateral wall of the orbit and the greater wing of the sph...

RATIONALE Sarcomatous or anaplastic carcinoma mural nodules presenting in ovarian mucinous cystic tumors are very rare. Here, we reported the ultrasonic and pathological features of 2 such cases. PATIENT CONCERNS A 60-year-old woman presented with a complaint of lower abdominal pain. Physical examination revealed a hard, palpable mass in her right lower abdomen with mild tenderness. In additi...

BACKGROUND Noninvasive intraductal papillary mucinous neoplasms (IPMNs) have a favorable prognosis; however, the prognosis of invasive intraductal papillary mucinous carcinoma (invasive IPMC) is poor. Identification of predictive factors for differentiating IPMC from benign IPMNs would assist in providing appropriate treatment. DESIGN Retrospective study (1999-2006). SETTING Wakayama Medica...

A 37-year female presented with complaint of lower abdominal pain and amenorrhoea to the Military Hospital, Rawalpindi. Ultrasound of pelvis showed a right adnexal cystic lesion. On investigation, CA-125 was raised. Her MRI scan of pelvis revealed a right adnexal mass of fluid intensity measuring 15.2 x 12.9 x 9.2 cm. Right ovarian cystectomy was performed and the specimen was sent for histopat...

Context Non-swelling autoimmune pancreatitis with multiple pancreatic pseudocysts is very rare. Case report A Seventy-five-year-old man was referred to our hospital for further examination of multiple pancreatic cysts with nodules detected by computed tomography.
