Middle cranial fossa arachnoid cyst presenting with subdural effusion and endoscopic detection of tear of the cyst--case report.
(41/57)
A 15-year-old boy presented with a case of middle cranial fossa arachnoid cyst associated with subdural effusion and manifesting as headache and vomiting after minor head injury. Computed tomography disclosed a cystic lesion in the left middle cranial fossa and ipsilateral subdural effusion. Fundoscopic examination revealed papilledema. A small tear of the cyst wall was confirmed endoscopically. Fenestration of the cyst was performed under the operating microscope. Postoperative course was uneventful. The tear in the outer wall of an arachnoid cyst may suggest the mechanism of occurrence of subdural effusion associated with middle cranial fossa arachnoid cyst. (+info)
Arachnoidplasty for traumatic subdural hygroma associated with arachnoid cyst in the middle fossa. Case report.
(42/57)
A 5-year old boy presented with an arachnoid cyst in the middle cranial fossa with mild midline shift manifesting as headache and loss of activity. Computed tomography (CT) showed subdural hygroma. Burr-hole drainage was carried out and symptoms were improved postoperatively. However, recollection of subdural hygroma was found on follow-up CT 3 weeks after subdural drainage. He underwent craniotomy, and tearing of the outer wall of the arachnoid cyst was observed. The ruptured cyst wall was tightly closed by arachnoidplasty to prevent cerebrospinal fluid leakage. Arachnoidplasty was effective for traumatic subdural hygroma with arachnoid cyst for reconstruction. (+info)

Subacute subdural hygroma and presyrinx formation after foramen magnum decompression with duraplasty for Chiari type 1 malformation.
(44/57)
A 15-year-old girl developed a rare case of subdural hygroma after foramen magnum decompression for Chiari type 1 malformation manifesting as rapid symptom deterioration around 10 days after uncomplicated operation with uneventful immediate postoperative course. Progressive enlargement of the subdural hygroma in both supra- and infratentorial spaces was followed by the development of hydrocephalus. Syringomyelia improved shortly after the first operation but then deteriorated with massive presyrinx formation. Reoperation with wide opening of the arachnoid membrane lead to a rapid resolution of the hydrocephalus and the presyrinx. The present case shows that wide opening of the arachnoid membrane is an effective therapeutic option. (+info)
