Few reported cases involve SLE and ADEM occurring simultaneously. Some of these cases were preceded by an infection, but others had no identifiable cause. One 2015 study suggests SLE can present as ADEM, because both occur due to abnormal immune regulation.1 ADEM with lupus rarely appears in the literature, and ADEM as the initial presentation is even rarer.
We present one such case below.
A 21-year-old African American male appeared in an emergency department with pain in his left calf, initially thought to be cellulitis. A few days after his initial evaluation, he was diagnosed with deep vein thrombosis (DVT), which was treated with apixaban.
One week later, he again required medical attention, and this time he was admitted for a 104ºF fever, chest pain and shortness of breath. A computerized tomography (CT) pulmonary angiogram performed to look for possible pulmonary embolism revealed a large pleural effusion and possible pneumonia. The patient was treated with broad-spectrum antibiotics and anticoagulation medications, and discharged home when clinically stable.
Only one day after his discharge from the hospital—roughly three weeks after his initial emergency department visit—the patient developed a severe headache over the temporal area and shortly after became minimally responsive with left-side paresis. The physical exam in the emergency department noted confusion, difficulty following commands, subconjunctival and periorbital edema, and left-side paresis.
The history, obtained mostly from his family, reported the patient had not complained about recent visual changes, nausea, vomiting or diarrhea; hadn’t traveled recently; and hadn’t recently changed sexual partners. Per their best knowledge, he didn’t suffer from malar rash, photosensitivity, discoid rash, oral/nasal ulcers, hair loss, arthritis, a history of serositis (i.e., chest pain, shortness of breath and a history of pleuritis or pericarditis), renal failure, seizures or psychosis, foot or wrist drop, cranial nerve palsy, blood count drops (e.g., anemia, leukopenia, lymphopenia, thrombocytopenia, etc.), Raynaud’s, dry mouth or dry eyes. The family also denied the patient was using any intravenous (IV) drugs or medications.
His family history was positive for possible rheumatoid arthritis and discoid lupus in the patient’s maternal grandmother.
