-enlist the signs commonly used in characterization of neural sheath masses -illustrate each Imaging sign with clinical examples -The Pathological correlates of Imaging signs used to identify neural sheath neoplasm and Tumour like masses  

A. Signs and Patterns in Neurogenic Tumours 1.Target sign 2.Split Fat sign 3. Comet tail sign 4. Fascicular sign 5 .Bag of Worms Pattern 6. Co Axial Cable sign. B. Signs and Patterns in Non Neurogenic Pathology -Segmental nerve enlargement,Displacement - Perineural Cuffing -Comet tail Sign -Nerve Edema sign -Entrapment -Bon fire Sign (pattern) Tumours: Lymphoma, Leukaemia Peri-neural Capillary haemangioma ,Bone lesions invading the neural sheath, Superior Sulcus Tumour, Ovarian neoplasms and Sacral GCT/Metastases Tumour Like masses: Sarcoid , Tuberculosis, Hansen’s Disease,Amyloid,GCT of Tendon sheath, Localized PVNS, Varices in Tarsal tunnel Each sign is defined, Illustrated diagrammatically and with clinical MRI and MR Neurography (STIR MRN/PROSET MRN,DTI based MR neurography) Pathological correlates like biopsy features are highlighted
