Abstract:
Posttransplant lymphoproliferative disorder(PTLD)is one of the more serious complications of organ transplantation.From October 2021 to December 2022, 3 patients with hepatic portal PTLD were hospitalized.Conventional ultrasonography hinted at hypoechoic area in porta hepatis.Enhanced CT revealed heterogeneous enhancement of soft tissue density in porta hepatis.PET/CT indicated higher metabolism of hilar mass.Two patients underwent contrast-enhanced ultrasound. "Fast-in-and-fast-out" sign(n=1)and no enhancement in all stages(n=1)were noted.Pathological examination revealed T/NK cell lymphoma(n=2)and B cell lymphoma(n=1). In conjunctions with previous literature reports, conventional ultrasound is frequently employed for detecting early cases of PTLD during clinical follow-ups.Contrast-enhanced ultrasound and enhanced CT may aid in making a differential diagnosis of PTLD.And PET/CT has high diagnostic accuracy for PTLD.
