FIGURE 106-1

Contrast-enhanced computed tomography (CT) Axial (A) and coronal (B) images show enlargement of soft tissue attenuation of the right palatine tonsil (arrows). The patient experienced mild dysphagia, and on direct visual inspection a deformity was noted. Biopsy proved posttransplant lymphoproliferative disease (PTDL).

FIGURE 106-2

A 35-year-old female transplant patient with diffuse marked thickening of the gastric wall compatible with biopsy-proved lymphomatous involvement.

FIGURE 106-3

Mesenteric soft tissue mass (M) consistent with a conglomerate of enlarged lymph nodes in a 13-year-old male patient with a history of liver transplantation 16 months ago.

FIGURE 106-4

Intestinal PTLD. CT scan shows diffuse marked thickening of an ileal loop in the pelvis (arrows). Although the wall thickening is marked, there is a mild luminal dilatation. This finding is typical of lymphomatous involvement of the small bowel.

FIGURE 106-5

(A–B) Extranodal PTLD. Soft tissue infiltration of the periportal space at the porta hepatis and at the falciform ligament fissure is noted (yellow arrows). Asymmetric cecal wall thickening is also seen (red arrow).

FIGURE 106-6

Axial CT scan shows scattered peribronchovascular elongated opacities that proved to be posttransplantation lymphoproliferative disorder with bilateral involvement (arrows).


FIGURE 106-7

A 62-year-old male patient with a history of alcoholic cirrhosis who received a liver transplant. CT scan shows a focal lesion in the right vocal cord (asterisk) with no evidence of compromise of cartilage or anterior commissure. Squamous cell carcinoma was diagnosed on biopsy.


FIGURE 106-8

This 36-year-old female patient received a liver transplantation 6 years ago because of cirrhosis secondary to primary sclerosing cholangitis. Chest posteroanterior (PA) radiograph (A) and CT scan (B) reveal multiple bilateral irregular-shaped pulmonary nodules. Some of the nodules are cavitated (arrows). Although an opportunistic infection was initially suspected, a diagnosis of multicentric lung adenocarcinoma was eventually made.


FIGURE 106-9

(A–B) Axial CT scans show subtle haziness and micronodules in the omental fat (yellow arrows). Ascitic fluid is seen surrounding the right lobe of the liver and loculated in the left hemipelvis. There is a cystic-solid right ovarian mass (red arrows), representing a case of ovarian carcinoma as part of a Molmenti Syndrome (Molmenti EP, Molmenti H, et al. ...
