Renal hemangioma is a rare benign tumor which usually causes unexplained painless gross hematuria with clotsin the renal pelvis or ureter. It isgenerally venous origin but may be arterial or mixed venoarterial; it may becapillary but is generally cavernous type which has predilection of submucosal, papillary,and medullary locations.It is very important ot include renal hemangioma in the diffrential diagnosis in cases of unexplained grosshematuria with clots in order to save the renal parenchyme. And preoperative selective renal angiography can offerhelpful diagnostic informations and may be helpful to decide surgical procedure. A case of surgically proven renalhemangioma is reported with a brief review of the literatures.

A 31-year-old woman with surgically proven spinal extradural granulocytic sarcoma was examined with magnetic resonance (MR) imaging. This patient had no evidence of systemic leukemia. The signal intensities of the mass on T1-weighted and gradient echo images were higher than those of spinal cord, which were different from iso-intensity of cases reported by other authors.

Syringomyelia is caused by heterogeneous etiologies. Syringomyelia secondary to arachnoiditis complicated by tuberculous meningitis is rarely reported entity, which has not been reported in Korea. We present a patient who had recovered from tuberculous meningitis and developed some years later a progessive disorder of the spinal cord clinically resembling syringomyelia, which was subsequently confirmed by MRI. The patient was treated with syringo-subarachnoid shunt.

OBJECTIVE: Clinical, radiographic, and outcomes assessments, focusing on complications, were performed in patients who underwent pedicle subtraction osteotomy (PSO) to assess correction effectiveness, fusion stability, procedural safety, neurological outcomes, complication rates, and overall patient outcomes. METHODS: We analyzed data obtained from 13 consecutive PSO-treated patients presenting with fixed sagittal imbalances from 1999 to 2006. A single spine surgeon performed all operations. The median follow-up period was 73 months (range 41-114 months). Events during perioperative course and complications were closely monitored and carefully reviewed. Radiographs were obtained and measurements were done before surgery, immediately after surgery, and at the most recent follow-up examinations. Clinical outcomes were assessed using the Oswestry Disability Index and subjective satisfaction evaluation. RESULTS: Following surgery, lumbar lordosis increased from -14.1degrees +/- 20.5degrees to -46.3degrees +/- 12.8degrees (p < 0.0001), and the C7 plumb line improved from 115 +/- 43 mm to 32 +/- 38 mm (p < 0.0001). There were 16 surgery-related complications in 8 patients; 3 intraoperative, 3 perioperative, and 10 late-onset postoperative. The prevalence of proximal junctional kyphosis (PJK) was 23% (3 of 13 patients). However, clinical outcomes were not adversely affected by PJK. Intraoperative blood loss averaged 2,984 mL. The C7 plumb line values and postoperative complications were closely correlated with clinical results. CONCLUSION: Intraoperative or postoperative complications are relatively common following PSO. Most late-onset complications in PSO patients were related to PJK and instrumentation failure. Correcting the C7 plumb line value with minimal operative complications seemed to lead to better clinical results.

Hodgkin's disease presenting with spinal cord compression owing to extradural and bone involvement is extremely unusual. A 48-year-old man presented with progressive lower extremity weakness resulting from spinal cord compression attributable to an epidural mass in the thoracic vertebrae. The patient underwent decompressive surgery, and was then treated with chemotherapy for Langerhans cell histiocytosis. However, the disease progressed, and we performed second decompressive surgery with stabilization. Subsequent histopathological investigations revealed Hodgkin's lymphoma of the bone. Here, we describe an unusual case of spinal Hodgkin's lymphoma and Langerhans cell histiocytosis to draw attention to this combination as a possible diagnosis in patients with mixed inflammatory cell infiltrate lesions in the spine.
