Multiple huge “cluster” and “galaxy” signs on chest radiography in a patient with pulmonary tuberculosis

In this article, we present a unique case of active pulmonary tuberculosis, with multiple huge “cluster” signs like fireworks, together with multiple “galaxy” signs. The repeated acid‐fast sputum smears and both bronchial washings were all negative forMycobacterium tuberculosis, but the acid ‐fast culture of sputum taken soon after the first bronchoscopy, and pleural fluid, turned out to be positive forM. tuberculosis at six weeks after admission. The present case clearly demonstrates that the “galaxy” and “cluster” signs are red herring signs of the low rates of isolatingM. tuberculosis, which should be differentiated from pulmonary sarcoidosis. A 62 ‐year‐old healthy man presented to our hospital due to a persistent fever of up to 38°C for one week. Thoracic computed tomography showed right pleural effusion with multiple large nodules up to 7 cm in diameter composed of numerous discrete small nodules like fireworks, the so‐called “clus ter” signs. Some of the large nodules had a hyper‐dense portion centrally surrounded by partially discrete small nodules, not as densely assembled, suggestive of the “galaxy” sign. The repeated acid‐fast sputum smears and both bronchial washings were all negative forMycobacterium tuberculosis, but the acid ‐fast culture of sputum taken soon after the first bronchoscopy, and pleural fluid, turned out to be positive forM. tuberculosis at six  week...

We present a case of a five-year-old child with clinical features mimicking several diseases, including tuberculosis. After failure of treatment based on the suspected diagnosis, an axillary lymph node biopsy showed noncaseating granulomas compatible with sarcoidosis and appropriate treatment was then started.

ConclusionWe describe one of the largest cohorts of consecutive uveitis patients referred to a department of internal medicine. The high percentage of uveitis associated with underlying (systemic) diseases highlights the need for a multidisciplinary approach, in order to reduce the diagnostic delay.

The secondary objectives were to describe the progression over time of the various etiologies and to identify local specificities. MATERIALS AND METHODS: We performed a retrospective epidemiological study of patients diagnosed with uveitis. All patients were referred to the regional cente...

Discussion Facial nerve palsy has been known for centuries, but in 1821 unilateral facial nerve paralysis was described by Sir Charles Bell. Bell’s palsy (BP) is a unilateral, acute facial paralysis that is clinically diagnosed after other etiologies have been excluded by appropriate history, physical examination and/or laboratory testing or imaging. Symptoms include abnormal movement of facial nerve. It can be associated with changes in facial sensation, hearing, taste or excessive tearing. The right and left sides are equally affected but bilateral BP is rare (0.3%). Paralysis can be complete or incomplete at prese...

Conclusions: Workplace exposures contribute to the burden of disease across a range of nonmalignant lung conditions in adults (in addition to the 100% burden for the classic occupational pneumoconioses). This burden has important clinical, research, and policy implications. There is a pressing need to improve clinical recognition and public health awareness of the contribution of occupational factors across a range of nonmalignant respiratory diseases.

Michael, Zsuzsanna Fabry, Andras Nagy, Matyas SandorSummaryMany autoimmune and infectious diseases are characterized by the formation of granulomas which are inflammatory lesions that consist of spatially organized immune cells. These sites protect the host and control pathogens like Mycobacterium tuberculosis (Mtb), but are highly inflammatory and cause pathology. Using bacille Calmette-Guerin (BCG) and Mtb infection in mice that...

The aim of our study was to identify the features which could help in the differentiation of infectious from non-infectious arthritis. The study was prospective and observational, and included 100 patients with oligoarticular inflammatory arthritis. The final diagnosis was made using standard diagnostic criteria and the patients were categorized into infectious and non-infectious g...

CONCLUSION: In our Egyptian cohort, more than half the patients had their retinal vasculitis as part of a serious systemic disease, or as part of an infectious process, as tuberculosis. And in view of the significant potential morbidity of these conditions, the local ophthalmologists need to be aware of these entities when faced with patients presenting with retinal vasculitis.

CONCLUSION: Granuloma with caseous necrosis is highly suggestive of TS but does not rule out FS. Certain fungi can exhibit this type of necrosis as do tuberculosis species. Suppurative inflammation, although rare in TS, does exist. Histiocytic type granuloma without necrosis is suggestive of brucellosis. PMID: 31012811 [PubMed - as supplied by publisher]
