Presentation A 3-year-old girl presents with a painful lump in the left upper neck, fever and elevated WBC counts. An ultrasound of the neck was performed.
Caption: Scan of the palpable painful lump
Description: A thick-walled mass with irregular borders is seen in the anterior triangle of the neck, displacing the sternocleidomastoid muscle anteriorly. The mass encloses a central anechoic area with debris and septa floating within.
Caption: Transverse scan at the site of concern
Description: The thick-walled fluid containing mass is noted again. The internal characteristics of the mass are well-appreciated in this image. Multiple enlarged lymph nodes [not depicted here] were also noted.
Caption: Color Doppler scan of the mass
Description: The peripheral margins of the mass shows increased vascularity. As expected, the central fluid containing area is devoid of color.
Differential Diagnosis Abscess, hematoma
