Abstract

Kikuchi disease of the iliac lymph node is rare, and even more rare is lymphadenitis with abdominal pain caused by Kikuchi disease. We report the US and CT findings of Kikuchi disease of the external iliac node in a 7 year-old-girl who complained of fever and abdominal pain in the left lower quadrant.

Keywords: Histiocytic Necrotizing Lymphadenitis, Abdominal Pain, Retroperioneal Space, Tomography, X-Ray Computed

Figures and Tables

Fig. 1

A. Ultrasonography of left lower abdomen shows 3 cm sized ill-defined echogenic mass (arrowheads) in left iliac fossa, between abdominal wall and iliopsoas muscle. Irregular shaped fluid collection with internal echoes is in the central portion of the mass.

B. Axial CT scan shows heterogeneously enhanced mass (arrowheads) in left iliac fossa anterior to external iliac vessels. C. Reformatted coronal CT image shows heterogeneously enhanced mass (arrowheads) in extraperitoneal space, external to sigmoid colon.
D. Histologic section shows extensive necrosis, especially subcapsular and paracortical areas (H & E, ×10). Inset: Necrotic areas are mainly composed of karyorrhectic debris (H & E, ×400).
