Cross-sectional imaging of small bowel malignancies.

Small bowel malignancies are rare neoplasms, usually inaccessible to conventional endoscopy but detectable in many cases by cross-sectional imaging. Modern multidetector computed tomographies permit accurate diagnosis, complete pretreatment staging, and follow-up of these lesions. In this review, we describe the cross-sectional imaging features of the most frequent histologic subtypes of the small bowel malignancies.

Thinking beyond peritoneal carcinomatosis: imaging spectrum of unusual disseminated peritoneal entities.

Although peritoneal carcinomatosis is the most common entity involving the peritoneum diffusely, a vast array of unusual diseases may affect the peritoneal surfaces. These entities can be further categorized into infectious, neoplastic, and miscellaneous, and miscellaneous conditions. Cross-sectional imaging, including computed tomography and magnetic resonance imaging are excellent modalities for further characterization of these unusual diseases.

A huge renal capsular leiomyoma mimicking retroperitoneal sarcoma.

A huge left renal capsular leiomyoma mimicking retroperitoneal sarcoma presented in a patient as an abdominal mass. Computed tomography displayed a large heterogeneous retro-peritoneal mass in the left side of the abdomen with inferior and medial displacement as well as loss of fat plane with the left kidney. Surgical exploration revealed a capsulated mass that was tightly adherent to the left kidney; therefore, total tumor resection with radical left nephrectomy was performed.

Primary twin ovarian pregnancy: case report and review of the literature.

Primary twin ovarian pregnancy is extremely rare. We present one such case in a 25-year-old primigravida who complained of lower abdominal pain and mild vaginal bleeding at 8 weeks after her last menstrual period. Transvaginal sonography revealed an empty uterus and presence of a gestational sac containing 2 dead embryos in the right ovary.

Jejunal gallstone ileus: an unusual site of gallstone impaction.

Introduction: Gallstone ileus is a life-threatening surgical emergency where characteristic imaging can be diagnostic. Jejunum is the one of the rare sites of gallstone impaction.

Materials And Methods: We hereby emphasize the role of multidetector computed tomography (MDCT) by describing a case of jejunal gallstone ileus with cholecystoduodenal fistula in a 59-year-old lady who presented with symptoms and signs of proximal small bowel obstruction.
