Autosomal-dominant polycystic kidney disease (ADPKD) is an inherited systemic condition with a predominant feature of cyst formation in both kidneys. An association with intracranial glioma has not been described previously in ADPKD. ⋯ These 2 independent cases of glioma suggest an unusual clinical manifestation of ADPKD. The potential association between ADPKD and glioma pathogenesis should be further explored.

Spinal arteriovenous malformations (AVMs) are rare lesions that may cause serious neurologic morbidity. With developments in endovascular technology and embolic materials, endovascular management of spinal AVMs has gained popularity. ⋯ Spinal AVMs manifesting as intracranial SAH are uncommon. These lesions are frequently overlooked on cerebral angiography and account for a small proportion of angiogram-negative SAHs. A negative angiogram in the setting of SAH should prompt a comprehensive evaluation of the cervical segmental arterial supply to exclude a cervical spinal AVM. Endovascular embolization may be effective in treating spinal glomus AVMs with good clinical outcomes and with complete angiographic obliteration. Onyx embolic agent should be considered as the agent of choice to manage spinal glomus AVMs.

Communicating branches between the tibial and common fibular divisions of the sciatic nerve have not been previously described. The aim of our study was to examine such neural connections. ⋯ To our knowledge, neural interconnections between the divisions of the sciatic nerve in the posterior thigh have not been described in the extant literature. Such data might help explain unusual neurologic examinations and alert the surgeon as to the potential for encountering such connections at operation.

To compare surgical outcome both radiologically and clinically after interventions for patients with Moyamoya disease. ⋯ Bypass surgery improved CVRC greater than synangiosis, which may correlate with decreased future stroke risks. The decision for bypass is to be balanced with a greater risk of postoperative neurologic deterioration in adults after this procedure. The hemisphere that did not undergo intervention also appeared to benefit from surgery performed on the contralateral brain.

Dural arteriovenous fistulas (DAVFs) of the sinus of the lesser sphenoid wing (SLSW) with leptomeningeal drainage are rare. We report a patient with a DAVF of the SLSW draining into the basal vein of Rosenthal (BVR) presenting with pontine hemorrhage. ⋯ A DAVF of the SLSW presenting with pontine hemorrhage is extremely rare, and DAVFs with deep leptomeningeal drainage should be included among a variety of etiologies of pontine hemorrhage.
