composed of variable proportions of dysmorphic blood vessels, smooth muscle, and adipose tissue. AMLs are typically solid lesions both radiologically and pathologically (1). Recently, AMLs, including the gross or microscopic cystic component, have been reported in the pathologic literature and discovered as AML embedding epithelial elements in the form of cysts and termed AML with epithelial cy...

The pathological gross examination of the kidney revealed a cystic mass on the outer surface measuring 6.0 cm in size. Cut surface showed a cavity filled with jelly-like material, clear fluid, and calcified material. Remaining part of the kidney was unremarkable. Microscopic examination of the cystic mass revealed presence of extensive cartilage, sebaceous glands, ciliated columnar epithelial c...

A 46-year-old man presented with abdominal pain. A CAT scan showed the presence of cysts in both the liver and kidneys. Moreover, a cystic mass was also observed in the middle of the small intestine and the typical appearance of small bowel intussusceptions was identified (Picture 1). The density was clearly the same as that of the cysts in the liver and kidneys, indicating that a cyst may have...

Cystic nephroma is a rare, benign multicystic lesion of the kidney. This tumor occurs both in children and in adults. In children, it is highly prevalent in males; in adults, it is more frequent in women. The term "cystic nephroma" represents two apparently different entities: pediatric cystic nephroma, a benign form thought to originate from metanephric tissue, and adult cystic nephroma, consi...

Mucinous cystic neoplasms (MCNs) of the pancreas in male patients are very rare. Though few cases of MCNs in male patients have been reported, it is difficult to reveal them preoperatively. The first patient was a 50-year-old man and was incidentally found to have a cystic mass of 51 mm in the tail of the pancreas. We performed a distal pancreatectomy. The second patient was a 73-year-old man, ...

Our purpose is to show the Multi-Detector CT (MDCT) findings of an intra-abdominal giant cystic lesion with midgut volvulus and to share our experience with giant lymphangiectasis mimicking a mesenteric cyst or a cystic mass. The pathological evaluation indicated that the cyst contained abdominal lymphatic material. Malrotation is usually detected in infants and children, but rarely in adults. ...
