ABSTRACT
Diagnosis: Malignant Melanoma History: The patient is a 79-year-old woman who presented with a two-day history of left lower extremity weakness associated with loss of proprioception, and vomiting after falling and striking the back of her head. The patient's past medical history is significant for multiple medical problems, including recent seizures. Findings: Non-contrast CT images of the brain demonstrate a 1.3 x 1.2 cm mass within the left optic nerve with multiple additional diffuse hemorrhagic lesions with associated vasogenic edema and mass effect. The largest and most concerning mass is within the right frontal lobe. This mass measures approximately 2.9 cm in greatest dimension. A whole body bone scan demonstrates intense focal uptake at the left femoral head, and subtle intake within the mid right femoral diaphysis. Ddx: Metastatic carcinoma (breast, kidney, lung, thyroid) melanoma, lymphoma sarcoma Dxhow: Biopsy/pathology of palpable lymphnode Exam: 3/5 left lower extremity weakness. Diminished proprioception. Loss of vision in left eye. No MeSH data available. |
