Case ReportsTreatment of suprasellar arachnoid cyst--two case reports.
A 10-month-old girl presented with mental retardation and enlarged head, and a 3-year-old girl presented with epilepsy, both due to suprasellar arachnoid cysts. Magnetic resonance imaging demonstrated the suprasellar arachnoid cyst and the relationship between the cyst and surrounding structures. The 10-month-old patient with accompanying hydrocephalus was treated by fenestration of the cyst wall into the basal cistern. ⋯ The 3-year-old patient presented without hydrocephalus and was treated by cyst-peritoneal shunting using a Codman-Medos programmable valve through craniotomy. Postoperatively, the cyst was reduced and there has been no recurrence for 2 years and 5 months. We consider that cyst-peritoneal shunting is the most effective treatment for suprasellar arachnoid cyst.

Case ReportsAsymptomatic hypothalamic hamartoma associated with an arachnoid cyst--case report.
A 42-year-old male presented with the complaint of mild left facial numbness. Magnetic resonance imaging demonstrated a solid tumor in the interpeduncular cistern and a huge arachnoid cyst in the left middle cranial fossa. The tumor appeared isointense to the surrounding cerebral gray matter on T1-weighted images and hyperintense to that on T2-weighted images. ⋯ Histological findings were characteristic of hamartoma. The mild left facial numbness was probably due to compression of the left trigeminal nerve by the arachnoid cyst. Asymptomatic hypothalamic hamartomas may occur in adults with atypical clinical presentations.

Review Case ReportsInstrumentational posterior fusion for atlanto-axial subluxation in a young child with Down's syndrome--case report.
A 3-year-old girl with Down's syndrome and myelopathy caused by atlanto-axial subluxation (AAS) was treated by C-1 to C-2 posterior fusion with a one-piece cervical device (OPCD). Instrumentation was required because the posterior arch of C-1 was too tiny and fragile to tolerate wiring. ⋯ She had been confined to bed by severe quadriparesis, but became able to walk without assistance 8 months after surgery. We recommend OPCD instrumentation and postoperative immobilization using a hard plastic corset for the treatment of AAS associated with Down's syndrome in young children.

Review Case ReportsEpidural hematoma associated with cephalohematoma in a neonate--case report.
A female neonate presented with cephalohematoma over the temporoparietal region on the right side. Computed tomography (CT) revealed the presence of an underlying epidural hematoma (EDH) and associated skull fracture with communication between the hematomas. ⋯ CT revealed cure without the need for an operative procedure. Aspiration is indicated for neonatal EDH with mild symptoms and liquefied cephalohematoma.

Review Case ReportsRuptured dissecting aneurysm of the peripheral anterior cerebral artery--case report.
A 27-year-old male presented with intracranial hemorrhage due to rupture of an idiopathic dissecting aneurysm in the A4 segment of the left anterior cerebral artery (ACA). This is a very rare location. He was successfully treated by resection of the aneurysm without neurological deficits. Surgical intervention is recommended for patients with intracranial hemorrhage due to ruptured dissecting aneurysm of the ACA to prevent rebleeding.
