Twelve-year-old boy presented with nasopharyngeal angiofi broma diagnosed with unilateral meningo-ophthalmic artery anomaly. Computed tomography scan shows midline nasopharyngeal angiofi broma (black arrow), with prominent right-side infiltration into the infratemporal fossa (white arrow).

Computed tomography (CT) scanning revealed a midline nasopharyngeal angiofibroma with prominent right-side infratemporal fossa infiltration [Figure 1].
Twelve-year-old boy presented with nasopharyngeal angiofibroma diagnosed with unilateral meningo-ophthalmic artery anomaly. Magnetic resonance imaging shows no intra-orbital infiltrations (black arrows).

Magnetic resonance imaging (MRI) confirmed exclusion of intra-orbital infiltrations [Figure 2].
Twelve-year-old boy presented with nasopharyngeal angiofibroma diagnosed with unilateral meningo-ophthalmic artery anomaly. Right lateral view angiograms of head show a) pre-embolization of tumor vessels and b) post-embolization of tumor vessels. Left lateral view angiograms of head show c) pre-embolization of tumor vessels and d) post-embolization of tumor vessels.

Pre- and post-embolization angiograms of tumor vessels are presented in Figure 3.
Twelve-year-old boy presented with nasopharyngeal angiofibroma diagnosed with unilateral meningo-ophthalmic artery anomaly. Left lateral view angiogram of the head shows internal carotid artery (black arrow) with no ophthalmic artery.

OA with ICA origin, and an M-OA anomaly that originated from the MA of the ECA with an OA variant and MMA branch variations [Figures 4-6]. Of particular interest in this case was that the OA variant had two intra-orbital parts, namely an orbital division with a distinct branching pattern to supply the nasal cavity and nose (i.e. ethmoidal and nasal branches) and an ocular division with a distinct branching pattern to supply the eyeball (i.e. ciliary and muscular branches) and the retina (i.e. the central retinal artery as witnessed by choroidal blush).
Twelve-year-old boy presented with nasopharyngeal angiofi broma diagnosed with unilateral meningo-ophthalmic artery anomaly. Left anteroposterior view angiogram of head shows meningo-ophthalmic artery anomaly (black arrow). (1: Ophthalmic artery variant; 2: Ocular division; 3: Orbital division; 4: Middle meningeal artery; 5: Anterior branch; 6: Meningeal branch; 7: Lacrimal branch).
