title: [A case of sarcoidosis with atypical high resolution CT findings].
abstract: A 36-year-old woman was referred to our hospital for investigation of erythema on the upper arms and thighs and abnormal radiological findings in the chest. A chest radiograph showed poorly defined fine nodules in both lung fields and high-resolution CT revealed fine nodular opacities with a random distribution throughout both lungs. No lymph node enlargement or peribronchovascular interstitial thickening were seen. Bronchoscopic evaluation revealed bronchial mucosal hypervascularity. Transbronchial lung biopsy and skin biopsy specimens showed noncaseating epithelioid cell granulomas. These findings confirmed the diagnosis of sarcoidosis. This is a rare case of sarcoidosis presenting with atypical high-resolution CT findings, which are difficult to differentiate from those of miliary tuberculosis or metastatic carcinoma.
