The differential diagnosis of sarcoidosis includes granulomatous infections, hypersensitivity pneumonitis, pneumoconiosis, autoimmune diseases (e.g., inflammatory bowel disease, primary biliary cirrhosis, several collagen vascular diseases (particularly Sjögren), drug reactions, chronic aspiration, and even diffuse fibrosing diseases. The non-caseating granuloma is the classic histopathology of sarcoidosis [1, 24] but there exists a spectrum of histology. Neurological manifestations of sarcoidosis are relatively rare but constitute a treatable cause of central and peripheral neurological manifestations. Pathognomonic. Blau syndrome and Sarcoidosis are both characterized by noncaseating granulomas on biopsy of affected tissues [6,20,30,42]. The granulomas of sarcoidosis are nonspecific lesions that, by themselves and in the absence of an identifiable etiologic agent, are not diagnostic of sarcoidosis or any other specific disease. Chest x-ray is less sensitive than CT for thoracic manifestations of sarcoidosis. Nine children had renal involvement at the time of diagnosis. Collagen vascular disease. The radiograph may appear normal despite the presence of pulmonary granulomas histologically (5-10% of cases). 23.
