A convexity meningioma presenting with an acute subdural hematoma

Abstract

Background: Meningiomas presenting with acute subdural hematomas are extremely rare. To the best of our knowledge, only 45 cases have been reported to date. We report on a case of a meningioma mimicking an acute subdural hematoma as well as a thorough literature review. Case Description: A 67-year-old man with no history of trauma was referred to our hospital with sudden onset of decreased level of consciousness and left hemiplegia. Computed tomography revealed an acute convexity subdural hematoma. Emergency surgery to remove the hematoma was performed. The hematoma was found to exist in the extra-axial space and the attached dura mater and pia mater remained intact. Pathological examination revealed a transitional meningioma, the World Health Organization Grade 1. Detailed medical history taken postoperatively revealed that a convexity meningioma had been diagnosed incidentally at another facility 1 year earlier. Conclusion: Acute subdural hematomas due to meningiomas are rare, and establishing the cause is challenging. Prompt and precise diagnosis of such entities may afford patients a better prognosis.

Solitary Fibrous Tumor With an Acute Subdural Hematoma: A Case Report and Review of the Literature

“…Meningiomas, like SFTs, can also cause bleeding, with 45 cases of meningiomas accompanied by subdural hematomas reported so far [ 10 ]. Differentiating SFTs from meningiomas in imaging is challenging, and the absence of the dural tail sign, typically seen in meningiomas, suggests SFT [ 3 ].…”

A case of microcystic meningioma associated with acute subdural hematoma in the posterior cranial fossa

“…Intracranial hemorrhage due to brain tumor accounts for 0.9%-10.2% of all cases of intracranial hemorrhage [5] . Malignant gliomas and metastatic brain tumors are the most likely to cause intracranial hemorrhage, and meningiomas cause as few as 1.3%-2.4% of all cases [ 1 , 2 , 5 ].…”

Subarachnoid hemorrhage is the most common type of hemorrhage associated with meningioma, whereas subdural hematoma is rare, with 57 cases reported [ 1 , 4 ].…”

“…Meningioma is one of the most common benign brain tumors and is characterized by abundant vascularity [1] , [2] , [3] , [4] , [5] . Intracranial hemorrhage tends to occur with malignant brain tumors such as glioblastomas or metastatic tumors, but is relatively rare in meningiomas [ 1 , 2 , 4 , 5 ]. Subarachnoid hemorrhage is the most common type of hemorrhage, whereas acute subdural hematoma is unusual [ 1 , 2 , 4 , 5 ].…”
