Haemophilic pseudotumour is a rare disease that occurs most often in femur, tibia, ilium or pelvic bone of a patient with haemophilia. Thus far, there have been only 31 reported cases in jaw bones and paranasal sinuses. Among them, the mandible is a more common site than the maxilla or paranasal sinuses. Here, we report a case of haemophilic pseudotumour in two parts of the maxilla. Contrast-enhanced CT showed an expansive and thinly corticated lesion with fluid attenuation at the left anterior maxilla which seemed like a post-operative maxillary cyst, ameloblastoma or odontogenic cyst. In addition, the thickened left palatal process of the maxilla seemed like fibrous dysplasia or intraosseous vascular malformation. Since haemophilic pseudotumour is not pathognomonic in radiological findings, when a patient who suffered from haemophilia or had taken anticoagulating agents has jaw lesion, haemophilic pseudotumour should be included in a differential diagnosis.
