Malignant peripheral nerve sheath tumor
Updates to Study Attributes
enhancing tumour at medial and superior aspect of the left orbit above the medial culpable fissure (1.7 x 0.8cm)
.extension of tumour along supra-orbital and frontal branches back to the left cavernous sinus demonstrated by nerve enlargement and abnormal enhancement
.the nerve lies in its position between the periosteum of the orbit and levator palpebrae superioris
.no extension into: intra-conal space, Meckel's cave or along cisternal portion of 5th nerve
.
Updates to Case Attributes
Malignant peripheral nerve sheath tumour of the left left V1 involving supra-orbital and frontal branches.
The patient went on to have surgical excision of the left eye, adjacent adjacent skin and soft soft tissue. Pathology confirmed the tumour type and involvement of the supra-orbital nerve, orbital apex and other extrinsic eye nerves.
The supra-orbital nerve margin was involved by a plexiform neurofibroma, as well the architecture of the tumour was plexiform on histology which is suggestive of neurofibromatosis type 1. Up to 70% of malignant nerve sheath tumours are associated with neurofibromatosis neurofibromatosis type 1.
