Case report
A 17-years old man, with a personal history of appendectomy in 2019 via McBurney’s incision. No familial medical history was noticed. He complained about a right abdominal pain lasting for few months. No use of steroids was related. Physical examination revealed a tender oblong-shaped mass, located in the right abdomen, mobile with breathing. It was 11 cm in diameter. His body mass index was 21.2 kg/m2. Blood tests were within normal ranges especially alpha foeto-protein, cancer antigen 19-9, and carcino-embryonic antigen. Abdominal ultrasound showed a heterogenous isoechoic mass of the segment 5 with an exophytic growth. Abdominal computed tomography revealed the existence of three lesions localized in segments 8,6, and 5. These lesions were 5, 2, and 11 cm in diameter respectively. These masses were heterogenous isodense spontaneously with slight contrast up take at the arterial phase and becoming iso-dense at portal and late phases (Figure 1). Magnetic resonance imaging demonstrated an exophytic lesion with a heterogenic signal (Figure 2). Its center has a hypersignal in T2 phase and a hyposignal in T1 signal without a significant contrast uptake at delayed phase. The other lesions localized in segments 8 and 6 showed hyposignal T2-weignted sequences, isosignal T1-weignted sequences, and a signal drop for in phase and out of phase sequences. Slight intake of contrast was described at the late phase.
