RESUMEN
Dandy walker syndrome is a kind of congenital anomaly consisting of absence of cerbellar vermis, cystic fourth ventricle and large posterior fossa. It can be associated with hydrocephaly. Generally it is treated with shunting but endoscopic third ventriculostomy can also be used. Our patient is a known case of dandy walker syndrome. She has been shunted due to hydrocephaly when she was 5 months old. She was presented with signs of raised intracranial pressure and endoscopic third ventriculostomy [ETV] was considered for the patient. As ETV didn't resolve the symptoms ventriculoperitoneal shunting was done. Patient discharged with good general condition. ETV is a novel procedure for hydrocephaly, but it should be considered that there are many factors that determine the success rate of it. Correct patient selection can increase success rate of this procedure
RESUMEN
The authors present a rare case of lumbar vertebral hemangioma extending to the epidural space with a bisected appearance and impinging on thecal sac. This 52-year-old lady presented with one year history of low back pain and bilateral leg radiation. Plain radiography showed vertical linear streaks at L2 vertebral body and axial computed tomography [CT] scan revealed small "polka dot" appearance within the vertebral body. Magnetic resonance imaging [MRI] showed low signal intensity on T1-weighted images in L2 vertebral body which was not characteristic for hemangioma. The patient underwent an L2 laminectomy, spinal canal decompression and posterior spinal instrumentation. This study indicates that lumbar vertebral hemangioma can extend to the epidural space and cause neurologic symptoms. Magnetic resonance imaging may not show diagnostic features, especially in active lesions and plain radiography and CT scan may be helpful
