Cerebellar Haemorrhage After Corrective Surgery for Scoliosis in a Girl with Arrested Hydrocephalus.

Abstract

A 14-year-old girl with congenital hydrocephalus and early-onset scoliosis presented with sudden onset of severe headache on the fourth postoperative day of scoliosis correction (definitive fusion). On evaluation, she was found to have cerebellar haemorrhage on computed tomography scan with the findings of obstructive hydrocephalus. Posterior fossa bleed with hydrocephalus contributing to raised ICP was suspected initially. Headache persisted despite treating the patient with analgesics and antioedema measures. There was no history of postural variation of headache. As the drain output was not coming down, even by the sixth postoperative day, low cerebrospinal fluid pressure headache was considered and the drain was removed, which resulted in marked improvement of headache. Subsequent wound exploration revealed grade III dural tear at D10 level, which was repaired and the headache subsided completely. The linear pattern of haemorrhage in the cerebellum is classical of remote cerebellar haemorrhage, which is seen rarely following spinal surgeries with associated dural tear.
