Differential diagnosis: Temporal artery pseudoaneurysm may mimic epidermal inclusion cysts, lipomas, hematomas, abscesses, sebaceous cysts, aneurysms, arteriovenous fistulas of the middle meningeal artery
, vascular and soft tissue tumors, lymphadenopathy, meningocele, and encephalocele.
In children, as the bony ridge that carries the middle meningeal artery

and a cortical vein with retrograde drainage into Labbe's vein (Figure 2).
The intrapetrosal portion is supplied by the superficial petrosal branch of the middle meningeal artery
and the stylomastoid branch of the posterior auricular artery portion is supplied by the stylomastoid, posterior auricular, superficial temporal, and transverse facial arteries.
