RESUMO
OBJECTIVE: The purpose of this article is to describe the diagnostic pitfalls caused by dropped gallstones left in situ after laparoscopic cholecystectomy. CONCLUSION: Dropped gallstones may rarely become symptomatic, causing recurrent abscesses. Diagnosis is challenging due to unusual clinical presentations, myriad locations, and radiologically occult calculi. Even asymptomatic dropped gallstones may cause diagnostic confusion by masquerading as intraperitoneal neoplastic deposits. Radiologists should be aware of techniques for identifying and retrieving dropped gallstones and be wary of their complications and imitations in patients who have undergone laparoscopic cholecystectomy.

Computed tomography (CT) has become established as an ideal form of imaging in small bowel obstruction (SBO), especially with modern day multiplanar imaging that is now widely available. CT can confirm the presence of SBO; show the site, level, and cause of obstruction accurately; and detect strangulation. It is important to recognize the common and unusual causes, but also conditions that mimic SBO. This review illustrates a spectrum of causes and discusses conditions that mimic SBO and their differentiation and the limitations of CT in the assessment of suspected SBO.
