Journal of Korean Neurosurgical Society 2008;43(4):198-200
Giant cavernous malformations (GCMs) occur very rarely and little has been reported about their clinical characteristics. The authors present a case of a 20-year-old woman with a GCM. She was referred due to two episodes of generalized seizure. Computed tomography and magnetic resonance image demonstrated a heterogeneous multi-cystic lesion of 7 x 5 x 5 cm size in the left frontal lobe and basal ganglia, and enhancing vascular structure abutting medial portion of the mass. These fingings suggested a diagnosis of GCM accompanying venous angioma. After left frontal craniotomy, transcortical approach was done. Total removal was accomplished and the postoperative course was uneventful. GCMs do not seem differ clinically, surgically or histopathologically from small cavernous angiomas, but imaging appearance of GCMs may be variable. The clinical, radiological feature and management of GCMs are described based on pertinent literature review.

Cavernous malformations (CMs) arising from the optic nerve and chiasm are extremely rare. The authors present a case of 39-year-old woman with CMs of the optic chiasm. She was referred due to sudden onset of bitemporal hemianopsia and headache, the so-called 'chiasmal apoplexy'. MRI findings suggested a diagnosis of hemorrhage and vascular malformation of the optic chiasm. Pterional craniotomy revealed an intrachiasmatic cavernous malformation with hemorrhage. The malformation was totally excised, but field deficits remained unchanged after surgery.

OBJECTIVE: The purpose of this study is to evaluate clinical and radiological outcomes analysis of the laminoplasty in the elderly patients, and to compare with the non-elderly patients. METHODS: A retrospective study of the short term result in patients who had treated with the laminoplasty for cervical spondylotic myelopathy (CSM) was performed. From January 2008 to December 2012, total 62 patients were operated with single open-door technique because of CSM; 28 patients were the elderly and 34 patients were the non-elderly. We evaluated some factors including sex, symptom duration, estimated blood loss during operation, operation time, hospitalization day, complications, pre- and postoperative modified Japanese Orthopedic Association (mJOA) score, recovery rate of mJOA score, achieved mJOA score, mean cervical canal width and expansion ratio of antero-posterior diameter in order to identify difference between the two group. Clinical outcomes were calculated with the recovery rate of mJOA score at the time of one year after operation. RESULTS: Mean age were 71.9 in the elderly group and 52.9 in the non-elderly group. Although postoperative mJOA score in the elderly group was lower than that of the non-elderly group, achieved mJOA score was statistically same between the two groups. Other clinical and radiological outcomes were also statistically same. CONCLUSION: We conclude that the laminoplasty also assures good clinical outcomes in the elderly patients with CSM, same as in the non-elderly group.

A 49 years old male patient who suffered from deterioration of posterior neck pain, left hand numbness, left lower limb pain and gait disturbance for 3 years visited our outpatient department. He had been diagnosed as non-dysraphic cervical intradural lipoma and operated in August 1990. On the radiologic images, we found the regrowth of non-dysraphic cervical intradural lipoma from C2 to C7 level, which surrounds and compresses the cervical spinal cord. Previous subtotal laminectomy from C2 to C7 and severe cervical lordosis were also found. Appropriate debulking of lipoma mass without duroplasty was successfully done with intraoperative neurophysiological monitoring (IONM). We are following up the patient for 24 months via outpatient department, his neurologic symptoms such as hand numbness, gait disturbance, left lower limb pain and posterior neck pain have improved. We describe a rare case of regrowth of non-dysraphic cervical intradural lipoma.

There have been very few reports in the literature of Guillain-Barre syndrome (GBS) after spinal surgery. We present a unique case of GBS following spinal fusion for thoracic vertebral fracture. The aim of this report is to illustrate the importance of early neurological assessment and determining the exact cause of a new neurological deficit that occurs after an operation.

There are few reported cases of post-operative spondylitis caused by Mycobacterium intracellulare. A 75-year-old female presented to our hospital with low back pain and paraparesis after a fall. The radiologic examination revealed compression fractures of L1, L3 and L4 and an epidural hematoma compressing the spinal cord. The dark-red epidural hematoma was urgently evacuated. Four weeks post-operatively, neurologic deficits recurred with fever. On magnetic resonance image, an epidural abscess and osteomyelitis were detected in the previous operative site. Five weeks post-operatively, revision was performed with multiple biopsies. The specimen were positive for acid-fast bacilli and traditional anti-tuberculous medications were started. Because the Polymerase Chain Reaction for non-tuberculous mycobacterium (NTM) was positive, the anti-tuberculous medications were changed to anti-NTM drugs. However, the neurologic deficits did not improve and persistent elevation of erythrocyte sedimentation rate and C-reactive protein were noted. Eight weeks after the revision, Mycobacterium intracellulare was detected in the specimen cultures. Despite supportive care with medication, the patient died due to multiple organ failure.

Pituitary apoplexy is a rare but potentially life-threatening clinical syndrome caused by the sudden enlargement of a pituitary adenoma secondary to hemorrhage or infarction. Pituitary apoplexy after cardiac surgery is a very rare perioperative complication. Factors associated with open heart surgery that may lead to pituitary apoplexy include hemodynamic instability during cardiopulmonary bypass and systemic heparinization. We report a case of pituitary apoplexy after mitral valvuloplasty with cardiopulmonary bypass. After early pituitary tumor resection and hormonal replacement therapy, the patient made a full recovery.

Intradural extramedullary (IDEM) ependymomas occur very rarely and little has been reported about their clinical characteristics. The authors present a case of a 57-year-old woman with an IDEM ependymoma. She was referred for the evaluation of a 4-month history of increasing neck pain and muscular weakness of the left extremities. Magnetic resonance imaging (MRI) of the cervical spine demonstrated an IDEM tumor with spinal cord compression. At the time of surgery, an encapsulated IDEM tumor without a dural attachment or medullary infiltration was noted, but the tumor capsule adherent to the spinal cord and root was left in place to minimize the risk of neurological sequelae. Histologic examination revealed a benign classic ependymoma. The post-operative course was uneventful and radiotherapy was performed. The patient showed an excellent clinical recovery, with no recurrence after 5 years of follow-up.

Syringomyelia associated with tuberculous meningitis is an extremely rare condition. Only a few studies have reported clinical experience with syringomyelia as a late complication of tuberculous meningitis. Twenty-six years after a tuberculous meningitis episode, a 44-year-old man presented with progressively worsening spastic paresis of the lower limbs and impaired urinary function for 2 years. Radiological examination revealed syringomyelia extending from the level of C2 to T9 and arachnoiditis with atrophy of the spinal cord between C2 and T3. We performed laminectomy from C7 to T1, dissected the arachnoid adhesion and placed a syringo-pleural shunt via keyhole myelotomy. One year after the operation, his neurological condition improved. The postoperative control magnetic resonance imaging revealed the correctly located shunt and significantly diminished syringomyelia cavities. We aim to discuss the mechanism of syrinx formation following tuberculous meningitis and to share our surgical therapeutic experience with this rare disease entity.
