Overview

Other imaging studies for the diagnosis of desmoid tumor include ultrasonography, which demonstrates tumor size and location. On ultrasonography, desmoid tumors appear as well-defined lesions with variable echogenicity. with ill defined/irregular borders. On color Doppler, desmoids appear like muscles, may be lobulated and may show vascularity.

Other Imaging Findings

• Following different imaging modalities can be helpful in diagnosis of desmoid tumors:

Characteristic features of desmoid tumors on different imaging modalities

Imaging modality	Associated characteristic features
Ultrasonography	Ultrasound is a helpful diagnostic study particularly for desmoids involving the chest or abdominal wall On ultrasound, desmoid tumors typically appear as: Oval in shape Homogeneously anechoic or hypoechoic masses (variable echogenicity) Well or poorly defined solid soft tissue masses/lesions Lateral borders may appear ill defined or irregular No central necrosis or calcifications Should not be confused with cystic lesions
Color Doppler	Findings on color Doppler are as follows: Appear like muscles May be lobulated May show vascularity
Plain radiograph	Radiographs may show: A soft-tissue mass Localised periosteal thickening Direct bony destruction/invasion
Angiography	Angiography may show: Arterial stretching Neovascularity Tumor staining
