Hemangioendothelioma is a recently described uncommon vascular neoplasm, characterized by epithelioid tumor cells and borderline biologic behavior. Its histological features and clinical behavior are intermediate between those of hemangioma and angiosarcoma. Its four principal sites of occurrence are the soft tissue, liver, lung and bone. Its intracranial occurrence is extreamly rare. We report a case of primary cerebral hemangioendothelioma in a 29-year-old male patient. Key words:Hemangioendothelioma;Epitheloid cell;Intracranial.

Objectives : The objective of this study was to investigate the role of postoperative three dimensional short-range magnetic resonance angiography(3D-TOF MRA) in predicting the clinical outcomes following microvascular decompression(MVD) for the treatment of a hemifacial spasm(HFS). Material and Method : Postoperative magnetic resonance(MR) imaging was performed on 123 patients with a HFS between March 1999 and May 2000. All patients who had postoperative MR imaging were undertaken preoperative MR imaging. Of the 123 patients, 122 patients were included in this retrospective study. The degree of the detachment of vascular contact, and change of the position of offender were determined by pre- and postoperative 3D-TOF MRA. These findings were compared with the surgical findings and clinical outcomes. Results : Of 122 patients who had successful MVD, clear decompression of offenders of the root entry zone(REZ) of facial nerve was found in 106 patients(86.9%), partial decompression in 10 patients(8.2%) and contact of offenders to the REZ of facial nerve in 6 patients(4.9%) by the postoperative 3D-TOF MRA. Our patients demonstrated that the types of offender did not influence with the degree of decompression of REZ of facial nerve and with surgical outcomes(p>0.05). Also, there was no significant relationship between the degree of decompression of the REZ of facial nerve from offenders and an improvement of symptoms(p>0.05). Futhermore, there was no significant relationship between the degree of decompression of the REZ of facial nerve from offenders and an improvement time (p>0.05). Conclusion : Our data suggests that MVD of facial nerve alone may not be sufficient to resolve the symptoms in all patients with hemifacial spasm. Therefore, another unknown factors besides vascular compression may be involved to cause symptoms in certain patients and it may be necessary to remove these factors with MVD simultaneously to obtain the resolution of symptom.

Purpose: Methylenetetrahydrofolate reductase (MTHFR) is the main regulatory enzyme for homocysteine metabolism. In the present study, we evaluated whether the MTHFR 677C>T and 1298A>C gene polymorphisms are associated with SBI and plasma homocysteine concentration in a Korean population. Materials and Methods:We enrolled 264 patients with SBI and 234 healthy controls in South Korea. Fasting plasma total homocysteine (tHcy) concentrations were measured, and genotype analysis of the MTHFR gene was carried out. Results: The plasma tHcy levels were significantly higher in patients with SBI than in healthy controls. Despite a significant association between the MTHFR 677TT genotype and hyperhomocysteinemia, the MTHFR 677C>T genotypes did not appear to influence susceptibility to SBI. However, odds ratios of the 1298AC and 1298AC + CC genotypes for the 1298AA genotype were significantly different between SBI patients and normal controls. The frequencies of 677C-1298A and 677C-1298C haplotypes were significantly higher in the SBI group than in the control group. Conclusion: This study demonstrates that the MTHFR 1298A>C polymorphism is a risk factor for SBI in a Korean population. The genotypes of 677C>T and 1298A>C polymorphisms interact additively, and increase the risk of SBI in Korean subjects.

Compartment syndrome has a wide spectrum from muscle pain to a life- threatening condition, such as acute renal failure and disseminated intravascular coagulation (DIC). Intracerebral hemorrhage (ICH) due to compartment syndrome has not been reported. We report a patient who presented with ICH leading to death. A 25-year-old female with no significant past history developed extensive compartment syndrome followed by rhabdomyolysis, acute renal failure, DIC, and ICH. Although the patient underwent a fasciotomy and hemodialysis and received aggressive resuscitation with massive transfusions of blood and intravenous fluids, she died. This case stresses the importance of early diagnosis and prompt treatment of compartment syndrome to prevent devastating complications. (J Korean Soc Traumatol 2006;19:178-182)

Chordoid meningioma is a rare but increasingly recognized subtype of meningioma that has high tendency to recur and is known to be sometimes associated with Castleman syndrome. A 41-year-old woman presented with 2months history of progressive headache. Magnetic resonance image revealed a large extra-axial and well enhancing mass in the right frontal convexity that resembled a typical convexity meningioma. However, the histological and immunohistochemical examinations of the surgical specimen confirmed the diagnosis of chordoid meningioma. We describe a case of chordoid meningioma without systemic manifestations related to Castleman syndrome such as anemia and/or dysgammaglobulinemia.
