This case report presents the unique clinical presentation of an 18-year-old female patient with an 8-year history of a progressively enlarging pulsatile mass in the left parieto-occipital region of her scalp. Remarkably, there was no history of trauma, headache, or other associated neurological deficits. Advanced imaging techniques, including computed tomography angiography and magnetic resonance imaging, revealed a vascular lesion consistent with an arteriovenous malformation beneath the scalp. Notably, the arteriovenous malformation's nidus was primarily supplied by branches of bilateral superficial temporal and occipital arteries, with a more pronounced involvement on the left side. Further magnetic resonance imaging characterization confirmed the diagnosis as a high parieto-occipital arteriovenous malformation/dural arteriovenous fistula. This case underscores the importance of a multidisciplinary approach involving neurosurgery and interventional radiology to the diagnosis and management of complex vascular lesions, particularly when they occur in unusual anatomical locations, like in our patient. The long-term clinical course and outcomes of such cases warrant continued investigation.
