MALIGNANT NON-HODGKINS-LYMPHOMA OF THE CRANIAL VAULT - A CASE-REPORT

We present the case of a 19-year-old patient who was admitted with a s ubcutaneous scalp lump associated with bilateral papilloedema. CT demo nstrated a large heterogeneous vault lesion destroying the right parie tal bone. The mass was hyperdense and enhanced slightly with contrast. An important intracranial epidural extension was also demonstrated. T he mass was completely removed through a parietal craniectomy and hist ological examination was characteristic for a B-cell non-Hodgkin's lym phoma. Staging revealed other bony lesions and neoplastic cells were a lso found in the CSF. Systemic and intrathecal chemotherapy were admin istered. This report discusses both the clinical differential diagnosi s of scalp masses and the radiological diagnosis of skull lesions.
