Bottom Line: However, origin of the MMA from the basilar trunk is an extremely rare variant.The abnormal origin of the middle meningeal artery from the basilar artery was diagnosed by angiography performed for preoperative embolization of the tumor.We report on the case with a review of the embryologic basis, possible explanations for this aberrant origin, and its clinical implications.

ABSTRACT
Various anomalies for the origin of the middle meningeal artery (MMA) have been described in the literature. However, origin of the MMA from the basilar trunk is an extremely rare variant. We report on a 54-year-old female who presented with frequent headaches; magnetic resonance imaging showed a right parietal meningioma. The abnormal origin of the middle meningeal artery from the basilar artery was diagnosed by angiography performed for preoperative embolization of the tumor. We report on the case with a review of the embryologic basis, possible explanations for this aberrant origin, and its clinical implications.

Figure 1: Axial T2 weighted (A) and post contrast T1 weighted (B) images show an intensely enhancing dural based lesion.

Mentions: A 54-year-old right handed white female presented to the emergency department complaining of frequent headaches over a 6-month period. On examination, she had a left-sided pronator drift, mild spasticity of the left lower extremity, and hypoesthesia of the left side of her body. She underwent brain magnetic resonance imaging, which showed a 3 × 4 cm sized right parietal dural-based soft tissue mass with radiographic characteristics consistent with meningioma. A considerable amount of surrounding vasogenic edema was observed with approximately 6 mm of midline shift (Fig. 1).
