Peribiliary cysts: Two case reports.

Peribiliary cysts are an incidental finding in patients with advanced liver disease. They were found to be common in fibrocystic disorders such as autosomal dominant polycystic kidney disease and polycystic liver disease, as well as cirrhotic livers. They result from obstruction-induced cystic dilatation of the peribiliary glands.

Congenital infiltrating lipomatosis of the face: Case report.

A rare disorder called congenital infiltrating lipomatosis of the face is characterized by a diffuse fatty infiltration of the soft tissues of the face. Muscle involvement and related bony hyperplasia may coexist. This particular form of lipomatous tumor is rare and typically appears in childhood.

Total cerebellar agenesis: A case report of a very rare condition.

Complete cerebellar agenesis is an extremely rare condition characterized by the complete absence of cerebellar tissue. Only a small number of cases have been reported, with varying motor and cognitive deficits. We describe a case of an 11-month-old baby with developmental delay, whose CT scan evaluation showed the complete absence of the cerebellum with no other associated cerebral malformation.

Benign and malignant prolapsed uterine tumors : 4 case reports of an extremely rare entities.

Prolapsed uterine tumors within the cervix or vagina, are attached to the uterine cavity by a soft tissue stalk. Malignant tumors and leiomyoma are the first diagnostic considerations for a prolapsed uterine mass with a visible stalk at MRI. This article describes 4 cases of patients who presented with large, necrotic prolapsed uterine tumors that were surgically confirmed and were diagnosed prospectively on the basis of MRI findings.

Bilateral thalamic infarcts: Percheron territory.

Blood supply to the human thalami is complex and multiple variants exist. The artery of Percheron is one of those variants and is characterized by a solitary arterial trunk that branches from one of the proximal segments of either posterior cerebral artery and sup- plies blood to the paramedian thalami. Its occlusion results in bilateral paramedian thalamic infarction sometimes extending to the midbrain.
