US of Pediatric Superficial Masses of the Head and Neck.

Superficial palpable masses of the head and neck are common in the pediatric population, with the vast majority of the lesions ultimately proven to be benign. Duplex ultrasonography (US) has emerged as the first-line imaging modality for the evaluation of superficial pediatric masses. Without utilizing radiation, iodinated contrast material, or sedation and/or anesthesia, US provides a means for quick and cost-effective acquisition of information, including the location, size, shape, internal content, and vascularity of the mass.

Sonography of pediatric superficial lumps and bumps: illustrative examples from head to toe.

Superficial lumps and bumps are extremely common in children, and the vast majority ultimately prove to be benign. Duplex/color Doppler ultrasound (US) has emerged as the first-line imaging modality for the evaluation of these superficial pediatric masses because it provides a means for rapid acquisition of information including size, shape, location, internal content and vascularity. More important, it does so without utilizing radiation, iodinated contrast material or sedation/anesthesia.

Idiopathic granulomatous mastitis masquerading as a postbiopsy abscess.

Idiopathic granulomatous mastitis (IGM) is a rare condition of unknown etiology with nonspecific findings. We present an unusual case of IGM manifesting after breast biopsy in a 42-year-old Turkish woman. IGM should be considered in the differential diagnosis when mastitis, carcinoma, and systemic diseases have been excluded and especially in the setting of a postbiopsy infection that is not responsive to antibiotic therapy.
