On ultrasound imaging, an abscess appears as a spherical or oblong anechoic or hypoechoic collection containing hyperechoic debris. The author thanks Linda J. Kesselring, MS, ELS, for her assistance in preparing the manuscript Use of color Doppler allows visualization of vascular structures near an abscess. The abscess itself should have no flow fast enough to cause a color signal. This abscess, however, has a vessel running through the center of it that would have otherwise been missed Ultrasound is considered the most useful initial imaging modality when a breast abscess is suspected. It is also the imaging method of choice to monitor progress, response to therapy and to ensure resolution. For the purpose of follow up the three dimensional measurement of the abscess and the volume of the contents should be given

Abscess drainage, also known as percutaneous fluid drainage, is a procedure to drain an infection in the body by insertion of a thin tube or catheter into the abscess using imaging guidance — such as a CT scan, flouroscopy or ultrasound — to drain the infection. Success is immediately apparent if the infected contents are aspirated 15.3.1 Ultrasound. Careful attention should be given to the access route in the planning of ultrasound-guided abscess drainage. Adequate guidance requires visualization of the entire route. 22 Drainage should not be done through two body cavities, and liver abscesses should never be drained through the pleural cavity In children, ultrasound is the primary imaging modality of choice to help limit radiation exposure. Typical findings on renal ultrasound consistent with renal abscess are presence of anechoic or septated renal masses (Fig. 12.16). Ultrasound may also be used to assist therapeutically; ultrasound-guided sampling for culture of a renal abscess. Description: The parotid gland shows the presence of a hypoechoic lesion.
