Article Figures & Data

Figures

  • FIGURE 1.
    FIGURE 1.

    Peritoneal scintigraphy study showing normal results. (A) Fifteen-minute dynamic infusion images of abdomen demonstrate progressive accumulation of tracer into peritoneal cavity, with uniform distribution. (B–E) Postinfusion anterior and posterior static images of abdomen (B and C) and chest (D and E) demonstrate no abnormal tracer collection. (F and G) Postdrainage images also demonstrate no abnormal tracer retention.

  • FIGURE 2.
    FIGURE 2.

    A 46-y-old woman on peritoneal dialysis who presented with acute shortness of breath and chest pain. (A and B) Chest radiograph (A) and axial CT scan (B) show moderate right pleural effusion. (C and D) Anterior and posterior postinfusion static images of chest demonstrate abnormal accumulation of tracer in right pleural cavity, confirming pleural–peritoneal leak.

  • FIGURE 3.
    FIGURE 3.

    A 60-y-old man with end-stage renal disease on peritoneal dialysis who presented with right scrotal swelling. (A) Postinfusion anterior static images of pelvis show abnormal bilateral accumulation of tracer (right greater than left, arrows) in the patent processus vaginalis and inguinoscrotal regions. (B) On coronal CT image, fluid (arrows) is seen in both patent processus vaginalis and right scrotum.

  • FIGURE 4.
    FIGURE 4.

    A 38-y-old man on peritoneal dialysis who was admitted to hospital with progressive right-sided abdominal swelling and shortness of breath. (A and B) Postinfusion anterior and posterior static images of abdomen show abnormal accumulation of tracer (arrows) in right lateral abdominal wall. (C and D) Subsequent CT and SPECT coronal images also demonstrate abnormal fluid and tracer collection (arrows) in right lateral abdominal wall, confirming abdominal wall leak.

  • FIGURE 5.
    FIGURE 5.

    A 38-y-old man on peritoneal dialysis who presented with mild abdominal discomfort and swelling in left lower abdominal wall. (A and B) Postinfusion planar anterior and lateral images of abdomen show focal abnormal accumulation of tracer (arrows) in left lower anterior abdominal wall. (C and D) Subsequent CT and SPECT axial images demonstrate abnormal fluid and tracer accumulation (arrows) at insertion site of abdominal wall catheter, confirming pericatheter leak. Patient was treated with reinsertion of peritoneal dialysis catheter. (E and F) Follow-up postinfusion planar anterior and lateral images demonstrate normal tracer distribution in peritoneal cavity, with resolution of pericatheter leak.
