Background: Post-traumatic pseudoaneurysm of the middle meningeal artery is a rare entity. We report an atypical case of a delayed presentation as parenchymal hemorrhage due to a ruptured middle meningeal artery pseudoaneurysm.
Case Description: A 22-year-old man with an alleged history of cranial trauma following a road traffic accident presented 10 days later with a new right temporal intraparenchymal hemorrhage. The CT revealed a differentially hypodense circumscribed structure in the anterior temporal location eccentrically in the hematoma. The cerebral angiogram depicted a pseudoaneurysm arising from the middle meningeal artery. The patient underwent craniotomy and excision of the aneurysm. On follow up, the patient was asymptomatic and had no focal neurological deficits.
Conclusion: Despite its rare occurrence, meningeal artery pseudoaneurysm should be considered as a possible etiology of a post-traumatic delayed presentation as an intracerebral hematoma. Prompt diagnosis and management are warranted in view of the mortality and morbidity.
