“…When compared to radiosurgery, surgical resection results in a high rate of complete tumor removal and a low recurrence rate for large tumors. [81011] However, stereotactic radiosurgery is considered to be a less invasive alternative to surgical resection and has been increasingly utilized over the past 20 years for the treatment of VS <3 cm in size. [1213]…”

Objective: Gamma Knife radiosurgery (GKRS) has been established as an effective and safe treatment for intracranial Schwannoma. However, communicating hydrocephalus can occur after GKRS. The risk factors of this disorder are not yet fully understood. The objective of the study was to assess potential risk factors for hydrocephalus after GKRS. Methods: We retrospectively reviewed the medical radiosurgical records of 92 patients who underwent GKRS to treat intracranial Schwannoma and developed communicating hydrocephalus. The following parameters were analyzed as potential risk factors for hydrocephalus after GKRS: age, sex, target volume, irradiation dose, prior tumor resection, treatment technique, tumor enhancement pattern, and protein level of cerebrospinal fluid (CSF) after GKRS. Results: Of the 92 patients, eight of them developed communicating hydrocephalus. Target volume and tumor enhancement pattern, and protein level of CSF ware associated with the development of hydrocephalus. Conclusion: In particular, patients with intracranial Schwannomas with large tumor size, ring enhancement patterns, and high protein level of CSF should be carefully observed.

“…Patients can be treated with ventriculoperitoneal shunts. Certain tumors (both benign and malignant) can also present with communicating hydrocephalus, such as vestibular schwannomas (in 13 of 291 patients, or 4.46%) 12 and high-grade gliomas (in 8 of 278 patients, or 3%). 13 These patients can be treated with a ventriculoperitoneal shunt or endoscopic third ventriculostomy.…”

With the increasing use of endovascular technology in the treatment of various conditions, there has been an inevitable rise in cases with extravasation of contrast medium. We present a case in which extravasation of a large quantity of contrast medium resulted in acute communicating hydrocephalus. A 78-year-old woman came to the hospital because of abnormal right-sided limb movement, and was diagnosed with occlusion of the left internal carotid artery. The patient underwent timely intra-arterial mechanical thrombectomy. Postoperative computed tomography (CT) examination revealed a high-density shadow of the left basal ganglia and left frontal lobe. Twelve hours later, the patient fell into a coma. Repeat head CT indicated acute hydrocephalus with no evidence of obstruction. The patient underwent emergency external ventricular drainage, and the drainage fluid was observed to be clear. The patient regained consciousness after the procedure and the drainage tube was removed 4 days later. The patient had no recurrence of hydrocephalus. The mechanisms and treatment of this condition are discussed.

“…In addition, fourth ventricle compression [6] or CSF flow alteration in basilar cisterns [7] is considered to be another potential mechanism. However, whether these side effects occur only in radiosurgery, including gamma knife, is still controversial [8,9].…”
