Since 3D-CTA demonstrates the surgical anatomy of VA-PICA aneurysms in detail, it is very useful for helping surgeons to select the optimal approach.

Subdural effusion, a common postoperative complication of extracranial shunting for hydrocephalus, is usually caused by excessive drainage of cerebrospinal fluid. Subdural effusion is thought to occur less frequently after a neuroendoscopic III ventriculostomy, and no reported cases have been symptomatic. We encountered a symptomatic subdural effusion with a component of hemorrhage 5 days after the latter procedure was performed to treat massive hydrocephalus in a 2-year-old boy.

A 36-year-old Japanese male, who 7 years previously had been diagnosed as having an ependymoma in the left parietal region, had received surgery, chemotherapy and radiotherapy. He later developed a rapid growth of multiple skin lesions on his back and extremities, which coincided with a regrowth of the tumor. Postmortem examination revealed that the ependymoma showed anaplastic transformation and necrosis; however, no malignancy was observed in the extracranial organs. The skin lesions were histologically diagnosed as seborrheic keratoses. We have, therefore, diagnosed the patient as having Leser-Trélat sign associated with anaplastic ependymoma.
