Polyradiculopathies from Schwannomatosis [PDF]
The Open Neuroimaging Journal, 2011 We describe a case of schwannomatosis presenting as radicular pain and numbness in multiple radicular nerve distributions. There were multiple peripheral nerve tumors detected by magnetic resonance imaging (MRI) at the left vestibular nerve, cauda equina, right radial nerve, thoracic paraspinal nerve, and brachial plexi.

Multiple neurogenic extracranial tumors. Clinical, MRI features, and diagnostic difficulties [PDF]
Romanian Journal of Neurology, 2013 A case of multiple neurogenic tumors is presented. A native MRI (head and cervical spine) identified multiple bilateral tumors in the intraorbital space and cervical tumors. Based on the clinical course, imaging features and diagnosis criteria a possible

A rare case of schwannomatosis of the extremities [PDF]
Journal of International Medical Research, 2020 A schwannoma is a benign tumor that arises from the myelin-producing Schwann cells that surround nerves. We herein report a case involving a 55-year-old man who first presented to our clinic with a schwannoma of the posterior tibial nerve and 5 years later with a schwannoma of the ulnar nerve.

A rare case of spinal schwannomatosis presenting as conus-cauda syndrome
Journal of Spinal Surgery, 2016 Multiple extra cranial schwannomas are generally associated with neurofibromatosis (NF) syndromes. Presence of multicentric schwannomas in absence of NF2 is a very rare entity.

SMARCB1/INI1 germline mutations contribute to 10% of sporadic schwannomatosis
BMC Neurology, 2011 Background Schwannomatosis is a disease characterized by multiple non-vestibular schwannomas. Although biallelic NF2 mutations are found in schwannomas, no germ line event is detected in schwannomatosis patients.

Recurrent Schwannomatosis of the Hand
HAND, 2020 Background: Peripheral nerve sheath tumors (PNSTs) are neoplastic soft tissue masses generated from the abnormal proliferation of Schwann cells. Often, these tumors occur in isolation and are known as schwannomas or neurilemmomas. The presence of multiple schwannomas is known as schwannomatosis.
