Target Population Adults with histologically proven or suspected vestibular schwannomas with neurofibromatosis type 2 (NF2). Question What is the role of bevacizumab in the treatment of patients with vestibular schwannomas? Recommendations Level 3: It is recommended that bevacizumab be administered in order to radiographically reduce the size or prolong tumor stability in patients with NF2 ...

A schwannoma of the larynx is a rare benign tumor that usually presents as a submucosal mass in the pyriform sinus and the aryepiglottic space, and this type of schwannoma constitutes a diagnostic and therapeutic challenge for otolaryngologists. We present here two cases of supraglottic schwannomas that were misdiagnosed as laryngoceles. Both were excised through a lateral thyrotomy approach wi...

Intraparotid facial nerve schwannoma is a rare benign neoplasm. Due to its rarity, it is not usually a prioritized diagnosis before surgery and may therefore lead to an unintentional treatment error. In this article, we report a single case of intraparotid facial nerve schwannoma. We were able to make a diagnosis with frozen biopsy. A complete resection of the mass while preserving the facial n...

INTRODUCTION The association of bowel tumor and inguinal hernia is rare. We report according to our research the first case of the migration of a small bowel schwannoma into an inguinal hernia. CASE PRESENTATION We report the case of a 51-year-old Moroccan malen admitted for a non-reducible right inguinal hernia in which surgical exploration showed the presence of a small bowel tumor that had...

Schwannoma also known commonly as neurilemmoma and schwann cell tumor is a benign nerve sheath tumor. About 1/3(rd) cases of schwannoma arise from the head and neck region but rarely from the nasal and paranasal sinuses. The recurrence rate in these cases has reported to be very rare. We report a rare case of schwannoma in a 60-year-old woman arising from the maxillary sinus further eroding the...

There is minimal data within the literature demonstrating the use of robotics to resect pelvic, benign schwannoma(s). Herein, we describe a case of a 46-year-old transgender male that presented with complaints of left-sided pelvic pain. Pre-operatively, the etiology was unknown. The patient underwent robotic-assisted laparoscopic excision of the pelvic mass, including a 5-6 cm resection of the ...

Olfactory groove schwannoma is a very rare tumor breaking through the skull base and orbit. The tumor may also extend to the subfrontal region intradurally. A case of olfactory groove schwannoma in a 35-year-old female, originating from the left olfactory groove with left proptosis, diplopia, supra-orbital mass, and gross intracranial extension is reported. The presence of bony scalloping on CT...

A full-term infant with an uncomplicated vaginal delivery presented with absent cry on routine newborn heelstick testing. Neurologic examination revealed paraplegia, absent reflexes, and a T4 sensory level. Spinal MRI showed an expansive, gadolinium-enhancing intramedullary mass from T2 to the thecal sac (figure, A and B). Biopsy confirmed a diagnosis of cellular schwannoma, WHO grade 1 (figure...

Case report of a posterior pharyngeal wall schwannoma in a 23-year-old female. Hypopharyngeal schwannoma is rare entities and at the time of writing we could find only 10 other cases reported worldwide and this is the eleventh. Complete excision was done intraorally and there is no recurrence after 1 year.

Cellular schwannoma is an uncommon variant of schwannomas that can occur in a peripheral nerve. Although cellular schwannomas typically do not differ in prognosis from regular schwannomas, they are known to cause local recurrence when not completely resected. Here, we report the case of a patient with cellular schwannoma of the posterior mediastinum, which recurred after 13 years.
