We report a case of maxillary hematoma. The patient, a 70-year-old man, presented with the chief complaint of a right nasal obstruction and nasal bleeding. A CT scan showed an isodensity mass, which occupied the right maxillary sinus with a destruction of the posterior and superior bony wall. Although a malignant tumor was suspected from these findings, we found a hematoma in the maxillary sinus and extirpated it. A histopathological examination confirmed the diagnosis. Endoscopic sinus surgery was performed to establish a communication between the maxillary sinus and the nasal cavity. We could not preoperatively distinguish the hematoma in the maxillary sinus from a malignant tumor. However, if surgeons notice a well-preserved mucous membrane in the maxillary sinus on the MRI findings, then it may be possible to differentiate a hematoma from a malignant lesion through careful examination.
