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.
