%X The gallbladder is affected by a large number of congenital anomalies, which may affect its location, number, size, or form. Some of these malformations are very rare and may lead to misdiagnosis. An ectopic gallbladder can be misinterpreted as agenesis of the organ or as a cystic hepatic mass when intrahepatic. Given the frequency and the wide acceptance of the ultrasonographic examination of the biliary tract, radiologists should be aware of these malformations. In some cases, ultrasonographic diagnosis can be difficult. However, the use of Computed Tomography can elucidate such cases. We present the case of a patient whose gallbladder had two combined malformations but caused no symptoms. Namely, the patient had a transverse ectopic gallbladder combined with a ¡°Phrygian cap¡± deformity. The incidence of ectopic locations of the gallbladder is 0.1¨C0.7%, whereas the ¡°Phrygian cap¡± deformity can be found in 4% of patients. There is no other cases with combination of these two entities reported in the literature. Ultrasonographic and CT findings are presented and aspects of this malformation are discussed. The clinical significance of ectopic gallbladder is also emphasized because it may alter the clinical presentation of biliary tract diseases and pose technical problems during surgery. 1. Introduction The gallbladder is an organ which can be adequately examined with ultrasonography and whose various congenital anomalies have been described. These anomalies may affect the gallbladder¡¯s location, number, size, or form. All these variations should be kept in mind during ultrasonographic examination with no visualization of the gallbladder so that misdiagnosis of agenesis is prevented [1]. We present a case of a patient whose abdominal ultrasonography revealed an ectopic gallbladder in transverse position and a Phrygian cap deformity in its fundus. These two anatomical variations are easily depicted with the use of ultrasonography. We complete the imaging approach of the patient by providing a Computed Tomography image. 2. Case Presentation An 87-year-old woman was admitted to the Emergency Department with pulmonary infection. During initial work-up, the patient underwent routine ultrasonography of the upper abdomen. The gallbladder could not be imaged in the gallbladder fossa when scanning subcostally in supine and left posterior oblique positions (Figure 1). However, when the probe was placed in the right lateral abdominal area, an elongated cystic structure was detected between the upper pole of the right kidney and the inferior surface of the right
