Systemic tuberculosis has been reported with varying neurological manifestations like meningitis, tuberculomas, myositis and neuropathy. Neuromyelitis optica (NMO) is a well known neurological entity which has been described in association with several systemic disorders like systemic lupus erythematosis, diabetes mellitus, hypothyroidism, exposure to insecticides etc. However, only a few cases of NMO have been reported in association with Mycobacterium tuberculosis. Here, we report a case of pulmonary tuberculosis in association with NMO to highlight the under-reported association of NMO with pulmonary tuberculosis presenting in a peculiar anatomical fashion i.e. longitudinal myelitis with predominant posterior column involvement.

Ocular tuberculosis is rare. We report a case of orbital myositis suspected to be infected with tuberculosis. In January 2008, a 34-year-old man experienced discomfort in the right eye. In May 2008, this patient developed right exophthalmos, diplopia, and pain in the right eye, and he was diagnosed with idiopathic orbital myositis. The patient underwent 2 courses of steroid pulse therapy; after which, the dosage of steroids was reduced. The steroid treatment reduced the eye pain, but his diplopia and exophthalmos persisted. By November of the same year, his general malaise had increased, and chest X-ray radiography and computed tomography were performed on 3rd December. On the basis of the imaging results, we suspected active pulmonary tuberculosis of the right upper lobe. The smear made by using the sample obtained after bronchial brushing was negative for acid-fast bacilli, but a Mycobacterium tuberculosis nucleic acid amplification test of the post-bronchoscopic sputum yielded positive results. Therefore, the patient was diagnosed with pulmonary tuberculosis. After the 2HREZ/7HR regimen of treatment, the extent of the tuberculosis lesions of the lung was reduced and the exophthalmos and eye pain were alleviated. Orbital myositis is inflammation of the extraocular muscles and can be either idiopathic, without a known etiology, or secondary to conditions such as tuberculosis, sarcoidosis, or hyperthyroidism. Our patient was not definitively diagnosed with tuberculosis of the eye. A definitive diagnosis of tuberculosis of the eye would require detection of granulomatous lesions in the eye or isolation of Mycobacterium tuberculosis by puncturing the eye muscles; however, our findings suggested the possibility that it was secondary to tuberculosis. We think that a careful examination of the chest should be performed for patients with ocular abnormalities.

Juvenile-Takayasu arteritis (j-TA) is a difficult diagnosis and some patients develop uncommon manifestations and associated diseases that may contribute to the delayed diagnosis. Our aim was to identify the misdiagnoses, the associated diseases and the atypical manifestations observed in a j-TA Brazilian multicentre study. 71 children and adolescents who met the classification criteria for j-TA were included. The misdiagnoses, the associated diseases and the atypical manifestations were evaluated. 19 (26.8%) patients had misdiagnoses. The most common of them was aortic coarctation in six (8.4%) patients, followed by rheumatic fever in five (7.0%) and one patient presented with both former diagnoses. Limb pain (two patients), spondyloarthropathy, juvenile idiopathic arthritis (JIA), spinal arteriovenous malformation, polyarteritis nodosa (PAN) and fever of unknown origin (FUO) were other misdiagnoses. Patients who had misdiagnoses previously to j-TA diagnosis presented a trend to have a longer diagnosis delay. 11 (15.5%) patients had 14 TA-associated diseases, such as pulmonary tuberculosis (5 patients), rheumatic fever (2 patients), spondyloarthropathy, polyarticular JIA, Crohn's disease, Prader-Willi disease, diabetes mellitus, Moyamoya and primary immunodeficiency. 7 (9.9%) patients presented 10 atypical manifestations, such as pyoderma gangrenosum, erythema nodosum, myositis, chorea, enthesitis, episcleritis, uveitis, hepatomegaly, splenomegaly and necrosis of extremities. Our study emphasizes the main misdiagnoses, associated diseases and atypical manifestations that occur in patients with j-TA and warns of the features that may alert paediatricians to this diagnosis, such as constitutional symptoms and elevated inflammatory markers.
