• When it is overproduced, the result is an abnormal nerve sheath.
• Benign peripheral nerve sheath tumors include schwannomas and neurofibromas.
• The cause was a type of cancer called nerve sheath sarcoma, said his wife, Marilyn.
• Other uncommon locations are the lateral ventricle, foramen magnum, and the orbit / optic nerve sheath.
• About 10 % of plexiform neurofibromas undergo transformation into a malignant peripheral nerve sheath tumor ( MPNST ).
• Optic nerve sheath fenestration is an orbit or the creation of an area of scar tissue that lowers the pressure.
• Malignant peripheral nerve sheath tumors are a rare type of cancer that arise from the soft tissue that surrounds nerves.
• Consequently, neurothekeoma and nerve sheath myxoma are likely not related histogenetically, although they are similar in appearance and in behavior.
• These tumors include the tumors involving the orbit and optic pathways, which include optic nerve gliomas and optic nerve sheath meningiomas.
• Microscopically, the lesions described closely resembled the tumor,  nerve sheath myxoma,  an entity first described by Harkin and Reed.
• Features common in neurofibromatosis-Lisch nodules, bone abnormalities, neurofibromas, optic pathway gliomas and malignant peripheral nerve sheath tumors-are absent in this condition.
• In certain cancers, such as peripheral nerve sheath tumors, high expression of its encoded protein is also associated to poor patient survival.
• Mercury exposures in excess of dietary selenium intakes in young children can have severe neurological consequences, preventing nerve sheaths from forming properly.
• Classical teaching was that, once crossed, the inferonasal fibers briefly loop back into the contralateral optic nerve sheath, before returning to the chiasm.
• In-flight ultrasound shows proximal kinking and increased optic nerve sheath diameter ( ONSD ) of approximately 12 mm that is consistent with raised ICPs.
• There he continues his work in developing therapies for primary and metastatic brain tumors, meningiomas, pituitary tumors, acoustic neuromas, spinal and peripheral nerve sheath tumors.
• There is a wide differential diagnosis, which includes spindle cell carcinoma, spindle cell melanoma, fibrosarcoma, malignant peripheral nerve sheath tumor and even biphenotypic sinonasal sarcoma.
• The role of cystatin C in multiple sclerosis and other demyelinating diseases ( characterized by a loss of the myelin nerve sheath ) remains controversial.
• Since the time of their first description, it has been reported that neurothekeomas are likely not of nerve sheath origin, as implied by the term.
• MRI of the brain and eyes days postflight revealed bilateral flattening of the posterior globe, right greater than left, and a mildly distended right optic nerve sheath.
