We present the case of pineal gland arteriovenous malformation (AVM) with optic neuropathy in a 29-year-old male who presented to our hospital with diminished vision in both eyes associated with headache, dizziness, and generalized weakness for 3 years. Visual acuity was counting finger at 3 m in the right eye and counting finger close to the face in the left eye. Posterior segment examination showed papilloedema. Magnetic resonance imaging of the brain and orbit with angiography revealed AVM in the pineal gland area which was compressing over the cerebral aqueduct and floor of the third ventricle causing ventricular dilation.

| Introduction|| |
Arteriovenous malformations (AVMs) are the most common form of intracranial vascular malformations in adults. It is thought to be static congenital lesions; still, a subset may possess dynamic pathophysiological capabilities of growth, regression or other morphological changes with time. We present a case of pineal gland AVM with optic neuropathy in an young male.
| Case Report|| |
A 29-year-old male presented with diminished vision in both eyes (OU) which was associated with vertigo, dizziness, headache, and generalized weakness for 3 years. On examination, protrusion of posterior fontanelle was noted. Visual acuity in his right eye was counting finger at 3 m and left eye was counting finger close to face, with exotropia noted in OU, more pronounced on the left side. On slit-lamp biomicroscopy, anterior segment was within normal limits and posterior segment examination with 90 Diopter lens showed papilloedema [Figure 1]. Provisional diagnosis of suspected intracranial lesion with optic neuropathy was made. Magnetic resonance imaging of the brain and orbit with magnetic resonance angiography revealed a large vascular malformation in the pineal gland area extending into the cerebral aqueduct and roof of fourth ventricle with multiple feeders vessels predominantly from the posterior cerebral arteries [Figure 2]. The lesion was also compressing the cerebral aqueduct and floor of the third ventricle causing mild upstream ventricular dilatation suggestive of obstructive hydrocephalus [Figure 3]. The patient was immediately referred to neurosurgeon for further management.

| Discussion|| |
AVMs have been defined as congenital high-flow shunts between arteries and veins with a central tangled nidus devoid of capillaries. Hydrocephalus is least encountered neurologic problem in patients with un-ruptured AVMs. Focal neurological deficit, seizure, and headache are the most common symptoms. The treatment of AVM mainly depends mostly on its location which include observation, surgical removal, stereotactic radiosurgery, endovascular therapy, or a combination of these modalities.
