We describe an adult female patient diagnosed with spinal melanotic ependymoma. She underwent surgery with the aim of gross total resection, but only subtotal resection was possible. Therefore, the patient was re-evaluated 6 weeks following surgery. Radiotherapy was considered as further treatment. The diagnosis, clinical course, etiology and pathology are discussed on the basis of the current literature.

Introduction: Melanotic schwannoma (MS) is a rare neoplasm composed of Schwann cells with melanosomes in various maturation stages. While MS is typically observed in spinal nerve roots or peripheral nerves, their involvement in intraocular structures is uncommon. Here, we present a case of spontaneous globe rupture as the presenting feature of intraocular extension of a MS.

Intraosseous malignant melanotic nerve sheath tumors are extremely uncommon peripheral nerve sheath tumors that typically present with benign clinical and histopathological features but with more aggressive long-term behavior. These tumors commonly originate from the dorsal nerve roots, sympathetic chain, cranial nerves, and lumbar plexus but may be found throughout the body. It usually presents with gradual compressive symptoms over months to years, like the typical presentation of schwannomas.

This type of tumor is usually highly aggressive and malignant, with a poor prognosis. The clinical manifestations of spinal cord MMNST are mainly pain, paresthesia, muscle weakness, muscle atrophy, etc.

Background: Spinal muscular atrophy (SMA) is a devastating neuromuscular disease caused by hypomorphic loss of function in the survival motor neuron (SMN) protein. SMA presents across a broad spectrum of disease severity. Unfortunately, genetic models of intermediate SMA have been difficult to generate in vertebrates and are thus unable to address key aspects of disease etiology.
