A 52-year-old man came to the clinic with occasional dysuria, urinary frequency, and nonspecific abdominal pain lasting 5 months. His medical history included alcohol abuse/dependence and hypertension. On physical examination, his abdomen was soft, nontender, and nondistended, with no palpable masses. An abdominal ultrasound identified a cystic mass in his pelvis. Magnetic resonance imaging of the abdomen and pelvis revealed a large cystic mass measuring 7.5 × 5.7 × 6.0 cm in the right lower quadrant of the abdomen (Figure 1). At elective exploratory laparotomy, a mass at the tip of the appendix was identified (Figure 2). The patient's postoperative course was uncomplicated, and he was discharged home on postoperative day 5.
