Symptomatic subdural hygroma as a complication of foramen magnum decompression for hindbrain herniation (Arnold-Chiari deformity).

Pseudomeningocele is a well known complication of foramen magnum decompression. Symptomatic subdural hygroma has not previously been described. We discuss a case of Arnold Chiari malformation type 1 in a 55-year-old Caucasian woman who underwent foramen magnum and upper cervical decompression and who developed a symptomatic subdural hygroma 2 weeks following surgery.

Supratentorial haemangioblastoma not associated with Von Hippel Lindau complex or polycythaemia: case report and literature review.

Solitary or multiple supratentorial haemangioblastomas are rare and may be associated with Von Hippel Lindau complex (VHLC), polycythaemia or a family history of VHLC. An extensive review of the literature (1902-1992) has revealed 112 cases. They account for 2-8% of all haemangioblastomas and are commonly intraparenchymatous (86.

Extradural application of bismuth iodoform paraffin paste causing relapsing bismuth encephalopathy: a case report with CT and MRI studies.

Bismuth iodoform paraffin paste (BIPP) is used in dressings in ear, nose, and throat, dental, and neurosurgical practice. Neurotoxicity due to absorption of bismuth from the BIPP pack is rare. It is preventable and reversible but likely to be fatal if unrecognised.

Spinal extradural arteriovenous malformation presenting with recurrent hemorrhage and intermittent paraplegia: case report and review of the literature.

Symptomatic spinal extradural arteriovenous malformations (AVMs) are uncommon. They usually present with slowly progressive myelopathy and/or radiculopathy and only rarely with spinal extradural hemorrhage (SEH). Histopathologic features of a true spinal extradural AVM causing an overt SEH have only previously been described in four cases.
