RESUMO

BACKGROUND: Spinal hemangiomas are rare vascular malformations resulting from proliferation of vascular endothelial cells. The cavernous form is the most common and represents 5-12% of spinal vascular malformations, while the capillary form is rare. CASE DESCRIPTION: A 56-year-old patient with no past medical history presented with progressive spinal cord compression symptoms localizing to the T10 level with MRC grade 4 proximal paraparesis. Preoperative MRI demonstrated a well-delineated, dumbbell-shaped, epidural lesion, without bony involvement, resulting in spinal cord compression at the T7 and T8 levels. The patient underwent gross total surgical resection of the lesion. At the one month follow up, the patient's strength improved to MRC grade 5, and sensation had fully returned. The histopathological diagnosis was a capillary hemangioma. Exclusively epidural capillary hemangiomas are extremely rare with only 26 cases reported in the literature. They are mainly located at the thoracic level (T4-T6). The MRI features include a well-circumscribed mass, hyperintense on T2-weighted sequence in 92% of cases, isointense on T1-weighted sequence in 88% of cases, and homogeneous contrast enhancement in 100% of cases. No tumor recurrence has been observed after gross total surgical removal. CONCLUSIONS: When evaluating progressive spinal cord compression by a purely epidural spinal lesion, the differential diagnosis should include capillary hemangioma, in addition to schwannoma, meningioma, and lymphoma. Early and complete surgical removal is the first line treatment.

RESUMO

OBJECTIVE: Several lines of evidence indicate a role for inflammatory processes in the development of cerebral aneurysms. Recently, polymorphisms in the promoter region of the interleukin 6 (IL6) gene were shown to be associated with intracranial aneurysmal disease. The purpose of this study was to verify the association of two functionally active polymorphisms (-174 G>C and -572 G>C) in the promoter region of the IL6 gene with the risk and clinical features of aneurysmal subarachnoid haemorrhage (SAH) in an Italian population. METHODS: A total of 179 consecutive aneurysmal SAH patients and 156 healthy controls were involved in the study. Cases and controls were genotyped for the -174 G

RESUMO

Thanks to advances in the stem cell biology of the central nervous system, the previously unconceivable regeneration of the damaged spinal cord is approaching reality. A number of potential strategies aim to optimize functional recovery after spinal cord injury. They include minimizing the progression of secondary injury, manipulating the inhibitory environment of the spinal cord, replacing lost tissue with transplanted cells or peripheral nerve grafts, remyelinating denuded axons and maximizing the intrinsic regenerative potential of endogenous progenitor cells. We review the application of stem cell transplantation to the spinal cord, emphasizing the use of embryonic stem cells for remyelinating damaged axons. Recent advancements in neural injury and repair, and the progress towards development of neuroprotective and regenerative interventions are discussed.
