Observation:
Mycosis fungoides is a type of malignant T-cell lymphoma that primarily involves the skin. In its later stages, mycosis fungoides can cause peripheral lymphadenopathy and also progress to widespread extracutaneous visceral involvement. The cutaneous lesions including patches, plaques, or erythroderma show no abnormalities at CT. In the stage of tumor formation, thickening or a mass of the skin is seen at CT. Evaluation of extracutaneous involvement, disease progression, and stage is the most important role of imaging in mycosis fungoides. Extracutaneous involvement causes a dramatic decrease in the survival rate. Therefore, CT demonstration of clinically unsuspected lymphadenopathy or abnormality in visceral organs such as hepatosplenomegaly is important. We report the imaging findings of a patient of mycosis fungoides with extensive cutaneous, nodal and visceral and unusual thyroid gland involvement.
