RESUMO

Leptomeningeal metastasis (LMM) is a rare complication of non-small cell lung cancer (NSCLC) that can present with a range of neurological symptoms depending on the site(s) of metastatic involvement. We present a case of a 54-year-old woman who was initially diagnosed with suspected inflammatory neuritis secondary to a known systemic lupus erythematosus (SLE) diagnosis after presenting with multiple months of progressive neuro-ophthalmologic symptoms; however, she was eventually diagnosed with LMM secondary to a previously undiagnosed NSCLC. This case both underscores the challenges of diagnosing LMM due to its nonspecific presentation, as well as highlights the importance of including LMM in the differential diagnosis for patients presenting with vague neurological symptoms in the context of another inflammatory disease process.

RESUMO

Wilson disease (WD) is estimated present in 6%-12% of patients younger than 40 years hospitalized with acute liver failure (ALF). Fulminant WD carries a poor prognosis without treatment. A 36-year-old man with HIV, chronic hepatitis B virus, and alcohol use had ceruloplasmin 6.4 mg/dL and 24-hour urine copper 180 µg/L. WD workup was otherwise negative, including ophthalmic examination, hepatic copper quantification, ATP7B sequencing, and brain MRI. ALF commonly features copper dysregulation. Few studies on WD biomarkers have included fulminant WD. Our patient with WD biomarkers and other causes of liver failure highlights the need to study copper dysregulation in ALF.
