case_images: Right iliac fossa ultrasound. A) Superficial intraperitoneal oblong mass in the right iliac fossa of 35mm non-compressible, hyperechoic, surrounded by a subtle hypoechoic line. B) without internal vascularity.

case_images: This ultrasound showed a normal appendix but also an anterior superficial intraperitoneal oblong mass in the right iliac fossa of 35mm non-compressible, hyperechoic, surrounded by a subtle hypoechoic line (Figure 1A) and without internal vascularity (Figure 1B).
case_images: Right iliac fossa MRI. A) T1 sequence showed a anterior superficial intraperitoneal oblong mass in the right iliac fossa of 35mm hypersignal slightly less intense than normal fat with a thin peripheral hyposignal. B) T1FS sequence showed hyposignal of the mass with a fine periperal hypersignal. C) Hypersignal T2 of the mass and hypersignal T2 in the fat around.

case_images: Magnetic resonance imaging (MRI) was performed and confirmed the presence of an anterior superficial intraperitoneal oblong mass in the right iliac fossa of 35mm hypersignal in T1 slightly less intense than normal fat (due to inflammatory stranding) with a thin peripheral hyposignal T1 (Figure 2A), hyposignal with a fine periperal hypersignal T1FS (Figure 2B), hypersignal T2 (Figure 2C).
