Acute renal failure in a healthy young adult after dextran 40 infusion for external-ear reattachment surgery.

Dextran 40 is used to improve the microcirculation after certain surgical procedures. We report a rare case of acute anuric renal failure in a healthy young adult after administration of dextran 40 to improve the microcirculation following ear-reattachment surgery. The renal failure was subsequently reversed by plasmapheresis and intensive care support. Although rare in the young and fit, the risk of developing acute anuric renal failure exists with administration of dextran 40 and appropriate monitoring is essential.

Compartmentalized maxillary sinus mucocele.

A rare case of compartmentalized maxillary sinus mucocele 12 years after a Caldwell-Luc operation is reported. The two separate mucoceles were drained intranasally by endoscopic sinus surgery. The clinical features of this mucocele are presented and the incidence, presentation and theories on formation of post-operative mucoceles are reviewed.

Dural cavernous angiomas in a child.

Dural-based cavernous angiomas are rare intracranial vascular lesions. Most of the reported cases are located in the middle cranial fossa, and those located outside the middle fossa are even more uncommon. Thus far, only 3 pediatric cases have been reported and all of them were found outside the middle fossa of a neonate. We would like to add the fourth pediatric case of a dural-based cavernous angioma located in the posterior fossa of a 5-year-old boy.
