Rare diagnosis of nodular lymphangitis caused by Mycobacterium marinum: MDCT imaging findings.
Mycobacterium marinum is an atypical mycobacterium that usually causes a solitary nodule on the hand ("fish tank granuloma") or less commonly, secondary erythematous channels and nodules spread along lymphatic drainage of the extremity, mimicking sporothricoid skin lesions of nodular lymphangitis. This report presents a case of this rare entity, a nodular lymphangitis caused by Mycobacterium marinum. Multidetector computed tomography (MDCT) imaging was very useful in determining the morphology (cellulitis with a few small subcutaneous nodules and channels) and the extension of the lesion.
