title: [Cranial hemophilic pseudotumor].
abstract: The haemophilic pseudotumor is defined as an encased hematoma that increases of volume progressively by episodes of recurrent hemorrhage. It is a rare complication of haemophilia occurring in 1-2% of patients with moderate or severe factor VIII or IX deficiency. Its more frequent location is in the long bones of low extremities and pelvis. We report a case of a 21-year-old man with moderate deficiency of factor VIII (19% of normal factor VIII activity) that developed a pseudotumor in the cranium. To our knowledge, this is the third case of the cranial hemophilic pseudotumor in medical literature.
