A Case of Multiple Meningiomas: Case Report

The neurosurgical frequency of multiple intracranial meningioma is low. The authors report a case of multiple meningiomas of supratentorial region and posterior fossa. The patient was 57-year-old female and presented with severe headache and vomiting. Computerized tomography and magnetic resonance imaging revealed multiple meningiomas in right parasagittal region. right temporal region and posterior fossa. The patient was treated successfully by stage operation and all of these pathological types was meningotheliomatous meningioma.

Problems in the Treatment of Patients with Ankylosing Spondylitis

The characteristic pathological lesions in ankylosing spondylitis are vertebral body osteoporosis, ankylosis of the apophyseal joints, intervertebral disc calcification, and ligamentous ossification. Calcification of the annulus fibrosis reduces the movement and elasticity of the intervertebral disc, causing this point to be the site of least resistance when the spine is subjected to trauma. The rigid spine may secondarily develop osteoporosis, further increasing the risk of spinal fracture. The ligamentous fragility and multiple fused vertebral segments cause the fractured ankylosing spondylitic spine to resemble a long-bone fracture. In ankylosing spondylitis patient who have sustained minor trauma, a complete radiological study of the entire spine and not just the symptomatic region must be performed for an accurate diagnosis, so that any fracture possible along the spine can be detected and thus prevent any medicolegal problems. The authors report 4 cases of ankylosing spondylitis including 2 cases with severe neurological abnormalities that had occurred after minor trauma.

Pain Relief from Dorsal Root Entry Zone(DREZ) Lesions Made with CO2 Laser in Brachial Plexus Injury Patients

Treatment of pain related to various types of deafferentation remains a neurosurgical challenge. Medical therapy and conventional surgical techniques for pain relief have not been effective due to this problem. Six patients with intractable pain following a brachial plexus injury were treated with dorsal root entry zone(DREZ) lesions. These lesions were made with CO2 laser. All patients were followed from 5 months to 5 years after surgery. Two-third of the patients were relieved of more than 50% of their preoperative pain. Post-operative neurosurgical complications were ipsilateral leg weakness and loss of proprioception in 2 cases. The laser technique is exact, makes uniform lesion, shortens the duration of the procedure, lessens cord manipulation and makes shalow penetration into the surrounding spinal cord. Dorsal root entry zone(DREZ) lesions made with CO2 laser appeared to be a satisfactory treatment for brachial plexus injury patients who have failed to respond to more conservative modes of therapy.
