Objective: Spinal dural arteriovenous fistulas (DAVFs) are insidious pathologies that, if left untreated, harbor potentially devastating consequences to the central nervous system. Spinal DAVFs are rare in the adult population and exceedingly uncommon in the pediatric population. In this report, we describe a spinal DAVF in a 3-year-old child whose initial presentation is subarachnoid hemorrhage (SAH).

The rod entered the left anterior frontal lobe, traveled through the ventricular system, narrowly missed the right posterior cerebral artery by less than 1 mm and exited through the right cerebellum. The rod was surgically extracted, and the child remained neurologically intact.

Intraorbital myoepitheliomas generally arise from the lacrimal gland. Intracranial myoepitheliomas are rare.

In this report, a patient developed a jugular foramen syndrome as the initial presentation of metastatic lung cancer soon after being diagnosed and treated surgically for extracranial atherosclerotic internal carotid artery disease. With the appropriate diagnosis established, he underwent local fractionated radiation therapy and systemic chemotherapy but succumbed to the disease.

However, it remains unclear whether these two forms of memory reflect neurally distinct processes. Furthermore, it is unclear whether recollection and familiarity can be best conceived as differing primarily in terms of retrieval processing, or whether they additionally differ at encoding.
