title: Subdural hemorrhage of the cauda equina. A rare complication of cerebrospinal fluid shunt. Case report.
abstract: We describe the case of a 16-year-old boy with idiopathic hydrocephalus, who developed cranial subdural hygromas and subsequent cranial subdural hemorrhage after a shunting procedure. Sciatica and radicular lumbar pain initially seemed to be unrelated to the proceeding implantation of a ventriculoatrial shunt. CT scan revealed a sharply demarcated hyperdensity in the lumbar subdural space with compression of the cauda equina. Differential diagnosis considerations included vascular malformations, vascular tumors, benign tumors of meninges or nerve sheets, ependymoma, lymphoma, and metastases. MR investigation did, in fact, clearly recognize this hyperintense space-occupying lesion as blood in the subdural space which outlined the cauda equina. We believe that the spinal subdural hematoma in our case represented an extension of intracranial subdural haemorrhage fluid into the spinal subdural space.
