Giant postsurgical pseudomeningocele by SPECT/CT cisternography.

We describe a case of a 32-year-old man with a giant pseudomeningocele seen on MRI examination 6 months after spinal surgery. Radionuclide SPECT/CT cisternography performed after intrathecal suboccipital injection of In-DTPA identified the site of cerebral spinal fluid leak at the L4 level, and the patient underwent surgical correction of the dural defect. A repeat MRI examination 8 months later showed no signs of recurrence.

Outcome Improvement in RPA I or II Patients With 1 or 2 Brain Metastases by Combined Surgery and Radiotherapy.

Background: To evaluate the role of surgery and postoperative radiotherapy in the management of brain metastases (BM): a retrospective analysis for overall survival (OS), local and brain control (LC and BC) of a series of 329 patients with recursive partitioning analysis (RPA) I or II with 1 or 2 BM in a single institution.

Methods: Patients were treated either with combined surgical resection and whole brain radiation therapy (WBRT) in 104 cases (31.6%) or with WBRT alone in 225 cases (68.
