Third nerve palsies in the pediatric population are most commonly caused by trauma, tumors, or vascular abnormalities. Cystic oculomotor nerve neuropathies, however, are rare. We report the case of a symptomatic cyst along and within the oculomotor nerve, which has not been described previously. Here, we report a case of a 3-yr-old girl presenting with a progressive painless oculomotor nerve palsy. A magnetic resonance imaging revealed a cystic formation along the cisternal and cavernous course of the nerve. Due to lack of alternative treatment options, surgery was offered. Intraoperative direct nerve stimulation allowed for identification of a non-functional part of the cyst wall and open fenestration and biopsy were executed. Histopathology revealed neuritis. Serology was negative for various pathogens. The oculomotor palsy rapidly resolved. At a follow-up 5 yr after surgery, the girl is asymptomatic and the cisternal part of the cyst remains collapsed. This is the first report of a symptomatic cyst along and within the oculomotor nerve treated effectively with open fenestration and decompression highlighting the importance of intraoperative neuromonitoring in cranial nerve surgery. Uncertainty remains regarding the etiology of this disease.

Stereotactic radiosurgery (SRS) has become one of the mainstays of treatment for patients with metastatic brain tumors. However, metastatic tumors with a large cystic component often exceed the size limit for safe and effective SRS. In such cases, surgical resection may not be the preferred first method of treatment, due to tumor location, patient co-morbidities, and patient preference. In these patients, volume reduction by cyst aspiration (CA) followed by SRS may be a viable alternative treatment option. To present the treatment of patients with cystic metastases using reservoir placement followed by SRS. Nine patients were treated with this method. We performed reservoir insertion for the aspiration of cystic component in each patient and followed that with outpatient SRS. Mean overall volume reduction from this treatment method was 78.5%. Mean volume reduction from the CA alone was 59.8%, and after SRS, a further 66.6%, accounting for some cyst reaccumulation between the time of surgery and SRS. Repeat reservoir aspiration was done a total of 10 times in 5 patients. Our study showed local tumor control in 7 of 9 patients (77.8%), while 2 patients required later surgical resection of their tumors. CA with reservoir placement followed by SRS is a good option for patients with large cystic brain metastases. The reservoir allows for repeat aspiration if needed. Catheter placement at the center of the cyst, and SRS within 2 to 3 wk of surgery, can maximize the likelihood of a successful outcome.
