Urachal mucinous tumor of uncertain malignant potential is very rare and is characterized by a multilocular cyst showing the proliferation of atypical mucin-secreting cells without stromal invasion. As in ovarian and appendiceal borderline tumors, it represents a transitional stage of mucinous carcinogenesis in the urachus. In addition, this tumor may recur locally and develop into pseudomyxoma...

Hydatid disease is an endemic disease which can affect any part of the body, the majority of cases originate within the liver and lung, intrathoracic extrapulmonary sites are very rarely affected. We present a rare case of a 24-year-old caucasian male patient with multilocular hydatid cysts, affecting the liver and diaphragm which we diagnosed accidently, both lesions were successfully managed ...

Ovarian carcinoid tumor is a rare neoplasm that may appear as a solid mass or often combined with teratomas or mucinous tumors. We report 2 cases associated with mucinous cystadenomas and describe their magnetic resonance imaging characteristics. On T(2)-weighted images, the tumors appeared as multilocular cystic masses with hypointense solid components as a result of abundant fibrous stroma in...

Figure (A) Coronal, contrast-enhanced, T1-weighted, head showed a left parietal ring-enhancing multilocular lesion showed restricted diffusion on axial diffusion-we seen on apparent diffusion coefficient (ADC) imaging.

A 42-year-female patient presented with a swelling on the left side of the face for the past 10 years. The radiograph shows multilocular radiolucency with evidence of root resorption. Histopathology reveals fibrous connective tissue exhibiting numerous odontogenic epithelial islands with peripheral tall columnar cells showing a reversal of polarity. The center of the island shows stellate retic...

Benign multicystic peritoneal mesothelioma (BMPM), also known as multilocular peritoneal inclusion cyst, is a rare tumour that occurs mainly in women at their reproductive age. The aetiology and pathogenesis are controversial. It originates from any abdominal peritoneal or pleural surface. The biological behaviour of BMPM is usually clinically benign. Here we present a case report of BMPM from ...

Cystadenoma, which accounts for 40-50% of all ovarian new growths, is a tumour of adult life, and uncommon in patients under 20 years of age. We have seen two cases, a girl (E.G.) of 13 with a rightsided, thin-walled, unilocular cystadenoma measuring 17 x 13 x 10 cm., and a 12-year-old child (M.O.) with a small, left-sided, multilocular cystadenoma; neither of these two girls had menstruated.
