We present four cases of pilocytic astrocytoma of the CPA (PA-CPA) that were treated in our department. Patients who received surgical treatment for PA-CPA from January 2004 to December 2019 were identified by a computer search of their files from the Department of Neurosurgery, T\u00fcbingen. Patients were evaluated for initial symptoms, pre- and postoperative facial nerve function and cochlear function, complications, and recurrence rate by reviewing surgical reports, patient documents, neuroradiological data, and follow-up data. We identified four patients with PA-CPA out of about 1500 CPA lesions (~\u20090.2%), which were surgically treated in our department in the last 16\u00a0years. Of the four patients, three were male, and one was a female patient. Two were adults, and two were children (mean age 35\u00a0years). A gross total resection was achieved in three cases, and a subtotal resection was attained in one case. Two patients experienced a moderate facial palsy immediately after surgery (House\u2013Brackmann grade III). In all cases, the facial function was intact or good (House\u2013Brackmann grades I\u2013II) at the long-term follow-up (mean follow-up 4.5\u00a0years). No mortality occurred during follow-up. Three of the patients had no recurrence at the latest follow-up (mean latest follow-up 4.5\u00a0years), while one patient had a slight recurrence. PA-CPA can be safely removed, and most complications immediately after surgery resolve in the long-term follow-up.<\/jats:p>","DOI":"10.1007\/s10143-020-01293-4","type":"journal-article","created":{"date-parts":[[2020,4,15]],"date-time":"2020-04-15T12:02:26Z","timestamp":1586952146000},"page":"1083-1091","update-policy":"https:\/\/doi.org\/10.1007\/springer_crossmark_policy","source":"Crossref","is-referenced-by-count":5,"title":["Surgical management of primary and secondary pilocytic astrocytoma of the cerebellopontine angle (in adults and children) and review of the literature"],"prefix":"10.1007","volume":"44","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-1879-8490","authenticated-orcid":false,"given":"Sasan Darius","family":"Adib","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Martin U.","family":"Schuhmann","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Johann-Martin","family":"Hempel","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Antje","family":"Bornemann","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Rocio Evangelista","family":"Zamora","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Marcos","family":"Tatagiba","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"297","published-online":{"date-parts":[[2020,4,15]]},"reference":[{"key":"1293_CR1","doi-asserted-by":"publisher","first-page":"466","DOI":"10.1097\/00005537-199704000-00008","volume":"107","author":"MS Ahn","year":"1997","unstructured":"Ahn MS, Jackler RK (1997) Exophytic brain tumors mimicking primary lesions of the cerebellopontine angle.
