Case contributed by Safwat Mohammad Almoghazy


Right shoulder swelling. Known metastatic thyroid carcinoma to lungs and bones.

Patient Data

Age: 62 years
Gender: Male

There is a large expansile destructive osteolytic lesion seen in the distal right clavicle with a soft tissue mass measuring about 8 x 6 cm.

Right thyroid lobe calcified mass is heterogeneously enhancing with mild displacement, and slight compression, of the trachea.

Multiple variably-sized suspicious pulmonary nodules are seen scattered within both lungs, more seen basally, the largest in the medial basal segment of the right lower lobe.

A destructive osseous lesion is seen implicating the distal portion of the right clavicle with associated heterogeneously enhancing soft tissue component.

A sclerotic lesion within the left humeral head is indeterminate. 


Case Discussion

Presented with right shoulder swelling and imaging showed a destructive lytic lesion of the clavicle and multiple lung nodules.  Radiological work-up, including thyroid FNAC, confirmed the diagnosis of metastatic thyroid cancer.
