Elastography, Vascularity and Grey-Scale Sonographic Features of  Cervical Lymph Nodes in Children with Infectious Mononucleosis

Infectious mononucleosis is a common cause of cervical lymphadenopathy in children, which can cause diagnostic difficulties. We present elastography, vascularity and grey-scale sonographic features of cervical lymph nodes in children with infectious mononucleosis. 416 cervical lymph nodes from 16 children with infectious mononucleosis were examined by B-mode ultrasonography, power Doppler ultrasonography and elastography. Lymph nodes were evaluated for their number, site, size, shape, echogenicity, echogenic hilus, vascular and elastographic patterns. Elastographic classification (ES) proposed by Furukawa and muscle-to-lymph strain ratio (SR) were used to evaluate elastograms of lymph nodes. Sonographic features of lymph nodes in patients with mononucleosis were compared with ultrasound image of normal cervical lymph nodes in children.
