An unusual intracranial tumour presenting in pregnancy

We describe a patient who presented in late pregnancy with deteriorating neurological status due to an intracranial capillary haemangioma causing mass effect and raised intracranial pressure. She became confused and uncooperative leading to practical difficulties in performing adequate radiological imaging. Decision regarding timing of delivery and craniotomy was not straightforward and required discussion between the neurosurgeon, obstetrician and anaesthetist based on assessment of fetal maturity and the need to perform a craniotomy to excise what was initially thought to be a meningioma. Caesarean section was performed under general anaesthesia. The tumour was resected three weeks later. Management of obstetric patients with brain tumours is complex, requiring knowledge of the physiological effects of pregnancy on tumour size and labour on intracranial pressure. Both of these may influence the choice of labour analgesia or anaesthesia for caesarean section. Anaesthetists must be aware of the difficulties of radiological imaging during pregnancy, particularly in confused patients. The conflicting requirements of general anaesthesia for craniotomy and caesarean section should be considered.
