    Abscess formation as a complication of a ruptured urachal cyst
    (Springer Heidelberg, 2007) Ilica, A. Turan; Mentes, Oner; Gur, Serkan; Kocaoglu, Murat; Bilici, Aslan; Coban, Hidayet
    The urachus is a midline tubular structure that extends upward from the dome of the bladder toward the umbilicus. This tubular structure normally involutes before birth, remaining as a fibrous band with no known function. Persistence of all or any portion of the fetal urachus results in several anomalies, the most common of which is the urachal cyst (Yu JS, Kim KW, Lee HJ, Lee YJ, Yoon CS, Kim MJ, Radiographics, 21: 451-4611, 2001; Ohgaki M, Higuchi A, Chou H, Takashina K, Kawakami S, Fujita Y, Hagiwara A, Yamagishi H, Surg Today, 33: 75-77, 2003). Although most urachal cysts are asymptomatic, there are a few reports about intraperitoneal rupture of infected urachal cysts, all of which caused peritonitis and sepsis (Ohgaki M, Higuchi A, Chou H, Takashina K, Kawakami S, Fujita Y, Hagiwara A, Yamagishi H, Surg Today, 33: 75-77, 2003; Kojima Y, Miyake O, Taniwaki H, Morimoto A, Takahashi S, Fujiwara I, Int J Urol, 10: 174-176, 2003; Agatstein EH, Stabile BE, Arch Surg, 119: 1269-1273, 1984). We report the imaging and operative findings of a patient, presented with a urachal abscess after a spontaneously ruptured urachal cyst.

    Extrahepatic abdominal hydatid disease caused by Echinococcus granulosus
    (Amer Roentgen Ray Soc, 2007) Ilica, Ahmet Turan; Kocaoglu, Murat; Zeybek, Nazif; Guven, Suleyman; Adaletli, Ibrahim; Basgul, Alin; Coban, Hidayet
    OBJECTIVE. The classical findings in hydatid disease caused by Echinococcus granulosus with liver or lung involvement are well known. However, diagnosing hydatid disease at unusual locations may be challenging because of variable imaging appearances depending on the host reaction. The purpose of this pictorial essay is to review the sonographic, CT, and MRI features of extrahepatic abdominal hydatid disease including intraperitoneum, retroperitoneum, diaphragma, bone, and soft tissue of the abdomen. CONCLUSION. Extrahepatic abdominal hydatid lesions have nearly identical imaging features, including the presence of cyst wall calcification, daughter cysts, and membrane detachment. The combinations of radiologic and serologic tests especially in patients living in the endemic areas contribute to the diagnosis. Despite their rarity, being familiar with the spectrum of radiologic findings in these unusual sites is helpful to improve diagnostic accuracy.

    Median arcuate ligament syndrome: Multidetector computed tomography findings
    (Lippincott Williams & Wilkins, 2007) Ilica, Ahmet Turan; Kocaoglu, Murat; Bilici, Aslan; Ors, Fatih; Bukte, Yasar; Senol, Ayhan; Ucoz, Taner
    Objective: We aimed to describe the clinical and multidetector computed tomography (MDCT) angiography findings of celiac, mesenteric, and renal artery entrapment by the median arcuate ligament. Materials and Methods: Patients (n = 453) who underwent MDCT abdominal aorta angiography in a period of 3 years were retrospectively reviewed for vascular compression by median arcuate ligament known as median arcuate ligament syndrome. The MDCT examinations were performed with 16-slice (n = 292) and 64-slice scanners (n = 161). The median arcuate ligament itself and adjacent vascular branches of abdominal aorta were assessed for compression by 2 different radiologists who are experienced on MDCT angiography more than 3 years. Both axial, multiplanar reformatted images and 3-dimensional angiograpbies were used for interpretation. Results: Twelve patients were found to have clinically significant vessel entrapments by median arcuate ligament; 6 of them with celiac artery, 4 of them with renal artery, and 2 of them with both celiac and mesenteric artery involvement. Patients with celiac and mesenteric vessel entrapments presented with epigastric pain. All patients with renal artery entrapment had resistant hypertension. The MDCT showed the proximal narrowing caused by compression of median arcuate ligament. The proximal portions of renal arteries pulled down and in toward the aorta, with mild to moderate narrowing. Conclusions: The MDCT examination with multiplanar images and 3-dimensional angiography is a noninvasive imaging technique that can be used with high accuracy in the diagnosis of median arcuate ligament syndrome.
