Abstract | BACKGROUND: OBJECTIVES/METHODS: We report a female patient who initially presented with a subacute spinal syndrome and a longitudinal spinal cord lesion on magnetic resonance imaging (MRI). As the brain MRI showed only unspecific white matter lesions and the cerebrospinal fluid was normal, a spinal cord biopsy was performed to exclude malignancies and revealed inflammatory demyelinating changes. In addition, after several deep vein thromboses and the detection of antiphospholipid antibodies, an antiphospholipid syndrome (APS) was diagnosed. Many years after the spinal cord biopsy, AQP4-ab were tested and found to be positive. We discuss the important differential diagnoses of LETM, give an overview of previously reported NMOSD cases in which a spinal cord biopsy was performed and highlight the crucial role of AQP4-ab testing for the differential diagnosis of longitudinal spinal cord lesions. RESULTS/CONCLUSIONS: Considering possible serious sequelae of spinal biopsy procedures, testing for AQP4-ab is mandatory in patients with unclear longitudinally extensive spinal cord lesions and should be performed preoperatively in all cases. In light of the heterogeneity of available assays, different detection methods should be used in doubtful cases. The relationship between NMO and APS needs further clarification; however, AQP4 IgG testing is recommended in patients presenting with APS and myelitis, optic neuritis or brainstem encephalitis.
