Patient with neurofibromatosis 1, slowly growing left thumb mass, please check an evaluate for ganglion versus solid soft tissue abnormality There is a multilobulated cystlike structure observed adjacent to the base of the first metacarpal along the volar and radial aspect. This discrete well marginated abnormality is superficial and does not appear to than or involve the underlying osseous structure. The focus measures collectively approximately 1.9 x 0.7 cm (image 31 series 5) axially and approximately 2 cm in craniocaudal dimension (image 5 series 8). Not all of these structures appear to communicate. No associated enhancement.Surrounding tendons and soft tissue structures are mildly deviated without direct involvement. Underlying osseous structures are also otherwise significant for moderate degenerative changes and an appearance that is grossly similar to the prior plain films. Marrow signal unremarkable.
