Bone metastasis - tibia

Case contributed by Dr Fabio Macori

Presentation

Squamocellular carcinoma of the lung. Swelling develops at the level of the middle third of the tibia. Smoker.

Patient Data

Age: 53 years
Gender: Female
X-ray

The lesion is well-seen only in the lateral projection

Ultrasound

Subcutaneous and periosteal reaction is demonstrated an ultrasound exam

CT

The examination documents the presence of a coarse lesion, mainly osteolytic, affecting the cortical bone of the diaphysis of the tibia that induces bone destruction associated with subcutaneous tissue reaction.

Coexist a fistula with the medullary cavity.

CT

Sagittal reconstructions and axial image, bone and tissue window, and 3D image

Case Discussion

Squamous cell carcinoma of the lungs can, frequently, give bone metastasis, mostly osteolythic.

Distal appendicular skeletal metastases, especially distal to the knee and elbow joints, are uncommon.

In this case, the metastasis is located in the third od tibial diaphysis

Biopsy of the lesion proved: "metastasis from squamocellular carcinoma of the lung".
