Hodgkin's lymphoma, with symptoms or right-sided bell's palsy. There is fluid within the right middle ear and mastoid air cells with extensive mucosal thickening. There is persistent diffuse enhancement of the bone marrow in the right lateral and central skull base, with mild overlying dural enhancement diffusely, including within the right internal auditory canal. Furthermore, there is ill-defined enhancing tumor in the right prevertebral and paravertebral spaces, with extension in the right jugular foramen, hypoglossal canal, foramen lacerum and perhaps into portions of the facial nerve canal. A small amount of tumor protrudes into the right cerebellomedullary angle cistern. There is no evidence of intracranial hemorrhage or acute infarct. The brain parenchyma and pituitary gland appear unremarkable. The ventricles and basal cisterns are normal in size and configuration. There is no midline shift or herniation. The major cerebral flow voids are intact. The orbits are grossly unremarkable.
Ill-defined right lateral skull base tumor with soft tissue components in the right prevertebral and paravertebral spaces, with extension in the right jugular foramen, hypoglossal canal, foramen lacerum and perhaps into portions of the facial nerve canal, as well as dural reaction, including within the right internal auditory canal. Persistent right tympanomastoid opacification, which may be related to Eustachian tube obstruction and/or otomastoiditis.
