It is unusual for pneumothorax to occur spontaneously during pregnancy. Its occurrence during or following caesarean section is extremely uncommon with only three other cases reported previously. In none of the reported cases, was the caesarean section performed under spinal anaesthesia. We report the successful management of a multigravida female patient, who developed spontaneous pneumothorax following caesarean section, performed under spinal anaesthesia. Tube thoracostomy was required for management and the patient had an uneventful recovery.
