Abstract PDF: We report a case of postlaminectomy pseudomeningocele which treated successfully by surgical removal with fat graft. A 23-year-old man complained of low back pain and right leg pain and a soft mass in the back at the site of the incision. Four months earlier, he had undergone surgery for herniated nucleus pulposus on L4-L5 segment and three times revision surgery for CSF leakage. A magnetic resonance imaging(MRI) study revealed a large cystic formation in the low back which communicated with a laminectomy site. At surgery, the pseudomeningocele was exposed subcutaneously and explored inside without further laminectomy. A dural tear was identified just around the nerve root with some suture materials and there was persistent CSF leaks. The dura was closed with interrupted sutures. Then we performed sandwich-typed fat graft with glue. Postoperatively, his leg pain was relieved completely and the wound was healed satisfactory without palpable back mass.

The extraaxial presentation of a medulloblastoma is rare. This article describes the case of a 12-year-old boy who presented with severe headache, nausea, and vomiting. The tumor developed in the left tentorium; it was misdiagnosed as a meningioma based on the radiology examination. We review the literature and discuss the atypical presentation of medulloblastoma.

Abstract PDF: Laserthermia is a new method of local hyperthermia using fiber optic guided probe with computer controlled Nd-YAG laser system. We used a synthetic sapphire probe and allowed irradiation with contolled low power laser energy (less than 5W), in different thermal condition (temprature:38.5-50 degrees C) for 10 minutes, in the normal brain tissue of 18 rabbits. In results, the histological changes of brain tissue was variable (myelin condensation, chromatin condensation, nuclear waving and palisading, RBC discoloration, cell necrosis) in microscopic findings after laser irradiation, but changing area was not occured proportionally in thermal condition level. Cell necrosis appears to over 44.5 degrees C and the distance was about 1.25 mm. This study, using computer controlled laserthermia system for interstitial local hyperthermia, may offer many advantages in the experimental treatment and clinical management of tumor. Minimizing normal tissue damage is now being developed.
