title: Post-traumatic intradiploic leptomeningeal fistula and cyst.
abstract: A 59 year old female patient presented with ataxia and difficulty in walking. The neurological examination revealed right homonymous hemianopia and ataxia. Radiographic evaluation revealed a large occipital intradiploic cyst mainly in the left suboccipital area. There was also moderate hydrocephalus and encephalomalacia of the left occipital pole. Bone window studies also demonstrated a growing fracture extending from the upper pole of the cyst to the vertex. Both pathologies were attributed to child abuse the patient suffered when she was a child. At first surgery, decompression of the cerebellum was followed by duroplasty and acrylic cranioplasty to the posterior cranial fossa. A month later, a shunt had to be inserted for hydrocephalus. At 7 months postoperatively, the patient is well and free of any symptoms or recurrence.
