Computed tomography imaging was performed to exclude a cerebral event and revealed multiple tumors within the left parotid gland. Duplex ultrasound and magnetic resonance imaging scans delineated multiple, hypoechoic tumors, round in shape and well defined without a hilar structure along the left mandible. For histological verification, a left-side partial parotidectomy and extirpation of an intraparotideal node was performed with use of a nerve-integrity monitor. Histomorphological analysis of the resected tissue revealed a benign schwannoma. Facial nerve function remained unchanged since the operation. The size of the nonresected tumors is currently monitored regularly by ultrasonography. Fibromatosis has been excluded.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusions<\/jats:title><jats:p>If multiple tumors occur in the parotid gland and the angle of the jaw, schwannomas need to be considered as a differential diagnosis. To plan the right diagnostic surgical intervention and prevent nerve damage, a thorough ultrasound examination is essential in preoperative diagnostic work-up for any suspicious lesion of the parotid gland and jaw region.<\/jats:p><\/jats:sec>","DOI":"10.1186\/s13256-021-03006-x","type":"journal-article","created":{"date-parts":[[2021,8,19]],"date-time":"2021-08-19T23:04:24Z","timestamp":1629414264000},"update-policy":"https:\/\/doi.org\/10.1007\/springer_crossmark_policy","source":"Crossref","is-referenced-by-count":3,"title":["Multiple schwannomas of the facial nerve mimicking cervical lymphoma: a case report"],"prefix":"10.1186","volume":"15","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-5028-9282","authenticated-orcid":false,"given":"Jan Philipp","family":"K\u00fchn","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Mathias","family":"Wagner","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Alessandro","family":"Bozzato","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Maximilian","family":"Linxweiler","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"297","published-online":{"date-parts":[[2021,8,20]]},"reference":[{"issue":"1","key":"3006_CR1","doi-asserted-by":"publisher","first-page":"14","DOI":"10.4103\/0022-3859.93247","volume":"43","author":"HK Shah","year":"1997","unstructured":"Shah HK, Kantharia C, Shenoy AS.
