Abstract

Leptomeningeal carcinomatosis is a rare complication of metastatic systemic malignancy, with lung cancer being the most common cause. We present a case of a 75-year-old man with a past medical history of right non-small cell lung carcinoma and ischemic stroke who presented with a persistent headache and swallowing difficulties. On evaluation, the patient was initially diagnosed with a subacute infarct of the right posterior frontal lobe following magnetic resonance imaging (MRI). The patient's headache and dysphagia worsened, increasing the possibility of brain metastasis. The patient underwent cerebrospinal fluid analysis including cytology and multiple MRI studies with no obvious explanation for the symptoms. The patient eventually developed multiple cranial nerve palsies, and a diagnosis of leptomeningeal carcinomatosis was made with neuroradiology consultation for the MRI.
