Diagnosis With Brief Discussion

Diagnosis
Thoracic desmoid tumor
Radiologic Findings
Simple radiographics
Chest PA shows a mass-like increased opacity with well-defined medial border in the Lt. upper lung field.
No definite evidence of rib erosion is noted.

CT
CT scan shows a homogeneously enhanced mass with chest wall extended. But, no rib destruction.
On saggital view, the mass surrounds the Lt. internal mammary artery without luminal narrowing.

Pathology
A lump of tissue from chest wall that contains three ribs. The mass shows fibrotic cut surface with intervening growth between intercostal spaces. Definitive bony destruction is not identified.
The predominant histologic appearances of the tumor is a hypocelluar arrangement of spindle-shaped cells with a fibromyxoid background.
Vimentin: Positive.
SMA(smooth muscle actin): focal positive.
Brief Review
Desmoid tumors belong to a group of disorders called fibromatosis, which show an infiltrating growth of well-diffentiated fibroblasts of myofibroblast. There are seen more frequently in 4th decade, predominantly in women. Although they can be locally aggressive and tend to recur after resection, these firm, fibroblastic tumors are considered benign and do not metastasize.

Historically, they have been divided into the abdominal, extraabdominal and intra-abdominal. Extraabdominal desmoid tumors chiefly involve the chest wall, shoulder, thigh and neck. Thoracic desmoid tumors occur most frequently in the intercostal muscle, usually after trauma, previous mastectomy, and excision of a neurofibroma.

The imaging appearance of these tumors depends on the relative amounts of fibroblast proliferation, fibrosis, collagen content, and vascularity of the tumor.

At CT, the masses are either ill-defined or well circumscribed. Before contrast material is administered, the tumors show variable attenuation, relative to muscle. After contrast material is administered, they may or may not appear enhanced. Usually, the lesions demonstrate higher attenuation than adjacent muscles.

At MR imaging, the masses are hypointense on T1WI. T2WI show variable signal intensity (low, medium, or high) relative to muscle.
