Sarcoid tenosynovitis, rare presentation of a common disease. Case report and literature review

Sarcoidosis is an idiopathic inflammatory disorder characterized by the presence of non-caseating tissue granulomas most commonly affecting lungs, lymph nodes and skin. Sarcoid skeletal involvement is relatively uncommon and in particular tenosynovitis. We describe an unusual case of sarcoidosis presenting with granulomatous tenosynovitis as the only manifestation of the disease, illustrating the radiological findings on different modalities followed by a review of the literature. Radiologists and clinicians should be aware of tenosynovitis as a manifestation of sarcoidosis as early and therefore appropriate treatment significantly alters patient's outcome and prognosis.
