What condition may be indicated by pulsatile tinnitus, headache, and visual disturbances following recent head trauma?

The presence of pulsatile tinnitus, headache, and visual disturbances following recent head trauma strongly suggests the possibility of a dural arteriovenous fistula (dAVF). This condition is characterized by an abnormal connection between a dural artery and a vein, which can lead to venous hypertension and result in various neurological symptoms.

Pulsatile tinnitus is particularly relevant as it often arises from turbulence in the blood flow through these abnormal connections. The combination of this symptom alongside headache and visual disturbances may indicate increased intracranial pressure or vascular compromise related to the dAVF. Visual disturbances can occur due to pressure on the visual pathways or involvement of venous drainage affecting areas of the brain responsible for vision.

In the context of other conditions, a cerebral aneurysm could also present with similar symptoms, but it may not typically cause pulsatile tinnitus unless there is a specific location or vascular complication. A subdural hematoma, while it could cause headaches and other neurological signs, is usually associated with unilateral symptoms and does not generally explain pulsatile tinnitus. Meningioma is a type of brain tumor that may cause headaches and visual problems but is less likely to specifically present with pulsatile tinnitus unless there is a particular vascular effect.

Thus, the combination
