A surgically cured case of chronic optochiasmal arachnoiditis presumably caused by concomitant right frontal arteriovenous malformation (AVM) is reported. When a 12-year-old boy, suffering from blurred vision for about 1 month, visited the Ophthalmological Clinic of Hirosaki University Hospital, only a chiasmal lesion was suspected because neuro-ophthalmological examination revealed no more than ophthalmic signs, such as bilateral diminution of vision (Vd, Vs = 0.2), concentric narrowing of visual fields and slight bilateral papilledema. The patient was referred to the Neurosurgical clinic for further examination. Left carotid angiograms showed no abnormalities but, thereafter the brain scintigram revealed an abnormal hot area in the right frontoparietal region. A right carotid angiography demonstreated an AVM in the posterior part of the right frontal lobe. This was fed through the right anterior and middle cerebral arteries and drained into the superior sagittal sinus through meandering dilated cortical vein.

We present a 45-year-old man with tussive headache and blurred vision found to have obstructive hydrocephalus from a neurocysticercal cyst at the cervicomedullary junction who underwent surgical removal of the cyst. We performed a suboccipital craniectomy to remove the cervicomedullary cyst en bloc. Cyst removal successfully treated the patient's headaches without necessitating permanent cerebrospinal fluid diversion. Neurocysticercosis is the most common parasite infection of the central nervous system causing seizures and, less commonly, hydrocephalus. Intraventricular cysts or arachnoiditis usually cause hydrocephalus in neurocysticercosis but craniocervical junction cysts causing obstructive hydrocephalus are rare. Neurocysticercosis at the craniocervical junction may cause Chiari-like symptoms. In the absence of arachnoiditis and leptomeningeal enhancement, surgical removal of the intact cyst can lead to favorable outcomes.
