title: [Multiple myeloma presenting as parasellar syndrome and cranial nerve palsies].
abstract: Cranial and intracranial locations have been rarely reported in multiple myeloma. Their occurrence as a harbinger of multiple myeloma seems to have a particular significance. In this report, we discuss a case of multiple myeloma presenting as parasellar syndrome and cranial nerve palsies. A 75-year-old woman was admitted to the hospital in June, 1994, with a 3-month history of headache and a 3-week history of diplopia and photophobia. Physical examination revealed right third, fourth and sixth cranial nerve palsies. MRI scan demonstrated a homogeneous, voluminous mass, isointense in T1-weighted images with the cerebral parenchyma and hyperintense in T2-weighted images, occupying the sphenoid sinus and extending within the sella turcica and right cavernous sinus. Lying above the mass and apparently separated from it by a thin rim of hypointensity was a normal pituitary gland. X rays revealed destructive changes of the sella turcica. A minimal disturbance of endocrine function together with a radiologically abnormal pituitary fossa indicated that the primary lesion might lie outside the pituitary fossa. A diagnosis of IgG-kappa type multiple myeloma was made by pertinent laboratory studies. She received local radiation to the intracranial mass (50 Gy) and conventional chemotherapy. Sixteen months after the therapy she is in good health.
