Multicompartmental blocks are commonly described in epidurals but not spinals. We describe a case of subarachnoid block performed in an obese patient which resulted in a clinical presentation resembling that of a subdural block. ⋯ The diagnosis of subdural block must be considered in patients with unusual presentations after a spinal anaesthetic. Factors affecting spread of hyperbaric bupivacaine are also highlighted.
