Neuromyelitis optica (NMO), mainly affecting optic nerve and spinal cord, can also manifest diverse ocular symptoms due to brain abnormalities. We present a cortical oscillopsia without nystagmus or head tremor in a patient with neuromyelitis optica spectrum disorder (NMOSD) with anti-aquaporin 4 antibody. This rare ocular manifestation, which is easily underestimated owing to absence of the typical nystagmus, can be an initial manifestation of NMOSD.

ObjectivesTo assess a case of paraneoplastic aquaporin-4 (AQP4)-immunoglobulin G (IgG)–seropositive neuromyelitis optica spectrum disorder (NMOSD) associated with teratoma and determine whether it is a paraneoplastic neurologic disorder.MethodsA single case study and literature review of 5 cases.ResultsA 27-year-old woman presented with diplopia, facial nerve palsy, paraplegia, sensory dysfunction of lower limbs, dysuria, nausea, and vomiting. Spinal cord MRI detected an extensive longitudinal lesion in the spinal cord, and brain MRI detected abnormal lesions in the right cerebral peduncle and tegmentum of the pons. CSF analysis revealed positive oligoclonal IgG bands (OCBs). The patient tested positive for AQP4-IgG, confirming a diagnosis of NMOSD. An abdominal CT scan detected an ovarian tumor. After steroid therapy and tumor removal, the patient progressively improved, with only mild sensory dysfunction. Histopathologic analysis of the tumor revealed a teratoma and the presence of glial fibrillary acidic protein (GFAP)+ neural tissue with AQP4 immunoreactivity, accompanied by lymphocyte infiltration. Including the present case, there have been 6 reported cases of AQP4-IgG–seropositive NMOSD associated with ovarian teratoma (mean onset age, 32.7 years). Of these patients, 5 (83%) presented with nausea and/or vomiting, positive OCB, and dorsal brainstem involvement. Pathologic analyses of the teratoma were available in 5 cases, including the present case, revealing neural tissue with AQP4 immunoreactivity and lymphocyte infiltration in all cases.ConclusionsThis study suggests that ovarian teratoma may trigger the development of AQP4-IgG–seropositive NMOSD. Further studies are needed to elucidate the pathogenesis of teratoma-associated NMOSD.

Objective:To describe leptomeningeal blood-barrier impairment reflected by MRI gadolinium-enhanced lesions in patients with aquaporin-4 immunoglobulin G (AQP4-IgG)–positive neuromyelitis optica spectrum disorder (NMOSD).Methods:A retrospective case series of 11 AQP4-IgG–positive NMOSD patients with leptomeningeal enhancement (LME) were collected from 5 centers. External neuroradiologists, blinded to the clinical details, evaluated MRIs.Results:LME was demonstrated on postcontrast T1-weighted and fluid-attenuated inversion recovery images as a sign of leptomeningeal blood-barrier disruption and transient leakage of contrast agent into the subarachnoid space in 11 patients, 6 in the brain and 6 in the spinal cord. The patterns of LME were linear or extensive and were accompanied by periependymal enhancement in 5 cases and intraparenchymal enhancement in all cases. The location of LME in the spinal cord was adjacent to intraparenchymal contrast enhancement with involvement of a median number of 12 (range 5–17) vertebral segments. At the time of LME on MRI, all patients had a clinical attack such as encephalopathy (36%) and/or myelopathy (70%) with median interval between symptom onset and LME of 12 days (range 2–30). LME occurred in association with an initial area postrema attack (44%), signs of systemic infection (33%), or AQP4-IgG in CSF (22%) followed by clinical progression. LME was found at initial clinical presentation in 5 cases and at clinical relapses leading to a diagnosis of NMOSD in 6 cases.Conclusion:This study suggests that altered leptomeningeal blood barrier may be accompanied by intraparenchymal blood-brain barrier breakdown in patients with AQP4-IgG–positive NMOSD during relapses.

Neuromyelitis optica spectrum disorder (NMOSD) is an uncommon antibody-mediated disease of the central nervous system. Its classic presentation includes long segments of spinal cord inflammation, optic neuritis with or without intractable vomiting, and hiccups. Here, we described a case of a 39-year-old woman with an atypical presentation of vertigo, which was finally diagnosed as NMOSD by a positive serum aquaporin-4 antibody.

ObjectiveTo present a case of two identical twins presenting concurrently with symptoms and subsequent initial diagnosis of neuromyelitis optica spectrum disorder (NMOSD).MethodsClinical, laboratory and MRI findings for both twins were reviewed and presented here.ResultsTwin A presented with right eye pain and subsequent blurred vision in right eye. MRI of the brain and spine demonstrated pre-chiasmal right optic nerve enhancement and T2 hyperintense lesions in the spinal cord at T7 and T9 levels. Cerebrospinal fluid (CSF) analysis was remarkable for NMO/aquaporin-4 (AQP4) fluorescence-activated cell sorting (FACS) titre of 1:32 and a serum NMO/AQP4-IgG positive titre of 1:10 000. Twin B presented with diplopia. MRI of the brain and spine demonstrated T2 hyperintense lesions in the periventricular cerebral white matter, in the periaqueductal white matter of the pons, in the midbrain and the cervical spinal cord. Neurological examination findings revealed incomplete right trochlear palsy, rotatory nystagmus, an incomplete left internuclear ophthalmoplegia and hyper-reflexia. CSF analysis was remarkable for NMO/AQP4 FACS titre of 1:256 and a serum NMO-IgG positive titre of 1:10 000. Both twins responded well to intravenous steroid therapy. There was no adverse environmental exposure present.ConclusionWe present an interesting and rare case of identical twins presenting concurrently and for the first time with NMOSD.
