Hemorrhagic acute disseminated encephalomyelitis as first manifestation of systemic lupus erythematosus

A young female with hypocomplementemic urticarial vasculitis associated with a rare CNS manifestation

This case report represents a rare case of 14-year-old female who diagnosed with hypocompementemic urticarial vasculitis syndrome that presents with glomerulonephritis, diffuse alveolar hemorrhage, and acute disseminated encephalomyelitis. The progression of the symptoms explained in the text below in which the final diagnosis was reached after a challenging approach. Patient was managed properly and followed up after treating with rituximab, although she represents no sign of the disease after a total of two cycles.

Pseudotumoral lesion as a manifestation of acute hemorrhagic leukoencephalitis (Weston-Hurst syndrome)

A case of acute hemorrhagic encephalomyelitis whose first manifestation was a pseudotumoral lesion in the corpus callosum is presented. The patient had an acute headache accompanied by visual hallucinations and subsequently developed convulsive status epilepticus. The initial CT scan showed a lesion with a pseudotumoral aspect in the splenius of the corpus callosum. Multiple microbleeds in the same location associated with vasogenic edema were seen in the MRI. A brain biopsy was necessary to obtain an accurate diagnosis. Corticosteroid management resulted in only a partial response. Weston Hurst syndrome is a variant of acute disseminated encephalomyelitis (ADEM) with an unfavorable prognosis.

Simultaneous presentation of acute disseminated encephalomyelitis (ADEM) and systemic lupus erythematosus (SLE) after enteroviral infection: can ADEM present as the first manifestation of SLE?

Central Nervous System (CNS) involvement of Systemic Lupus Erythematosus (SLE) includes a broad range of neuropsychiatric syndromes. Acute Disseminated Encephalomyelitis (ADEM) is a demyelinating CNS disorder characterized by encephalopathy and multifocal lesions predominantly involving the white matter on brain magnetic resonance imaging. ADEM associated with SLE has been only rarely reported. We report an unusual case of a 17-year-old girl who developed ADEM after enteroviral infection as the first manifestation of SLE. The authors emphasize that the patient's illness was preceded by enteroviral infection and that ADEM occurred before any other symptoms of SLE, which makes this case unique.
