SUMMARY A severely affected haemophilic boy became tetraparetic as a result of a spontaneously occurring intraspinal haematoma. Myelography defined the extent of the lesion and showed it to be extradural in site. Infusion of large doses of factor VIII concentrate led to dramatic improvement and avoided the need to operate.Intraspinal bleeding in haemophilia is extremely rare and recovery is even rarer. To date 14 cases have been recorded, and 11 of these have died. We report here a severely affected haemophilic patient who developed acute tetraparesis from spontaneous intraspinal bleeding; prompt treatment with large doses of factor VIII (antihaemophilic factor) contributed to a remarkable clinical recovery, accompanied by radiological resolution of the haematoma.
Case reportThe patient was a 20 year old, severely affected haemophilic male with a baseline factor VIII level of less than 1%. He was previously described when he sustained a ruptured left ureter in the Ibrox football disaster of 1970of (Forbes et al., 1971. Four days before his referral he had again been a spectator on the terraces at a football match during which he 'strained' his neck but had no direct trauma. After this he had experienced mild neck and shoulder pain which had been treated as a suspected muscular bleed with a single infusion of factor VIII concentrate (about 750 units), a dose which was sufficient to raise his plasma level to about 20% of normal. This level would normally be considered adequate for such a trivial bleed. At that time no neurological signs were apparent. However, next day he was ad-
