A spinal haematoma occurring in the subarachnoid as well as in the subdural space in a patient treated with anticoagulants

Abstract

A 75-year-old man on anticoagulant therapy suddenly experienced an excruciating back pain and subsequently developed a paraplegia. At operation a subarachnoid and a subdural haematoma were found, extending between the levels of the vertebrae T3 and L2. This extremely rare combination of haematomas may have been caused either by rupture of a small vessel in the arachnoid membrane or by rupture of the arachnoid membrane itself, secondary to a massive haemorrhage in the subarachnoid space.
