Recurrent duodenal diverticulitis after surgical resection of the diverticulum: a case report and literature review.

Duodenal diverticulitis has been considered a rare entity. The diagnosis with computed tomography has become a fast and noninvasive means of detection and guide to management. Cases of surgically resected duodenal diverticula reforming and reinfecting are rarer yet, often presenting with similar symptoms. Duodenal diverticulitis can present with a wide range of symptoms mimicking anything from gastritis to acute abdomen, or as in the case of our patient, as mid abdominal pain with newly developed liver abscess. According to the literature, duodenal diverticula are incidentally discovered at a rate of 5% to 10% in living adults and in up to 22% at autopsy.

Sonographic features of tubo-ovarian abscess mimicking an endometrioma and review of cystic adnexal masses.

A 36-year-old female presented with constant, worsening left lower quadrant pain without associated fever or vaginal discharge. Pelvic and transvaginal ultrasound examinations were performed which demonstrated a large complex cystic structure in the left adnexa with peripheral flow on color Doppler imaging. Given the sonographic appearance and patient symptoms, possibilities included endometrioma or hemorrhagic cyst. Tubo-ovarian abscess (TOA) and other cystic ovarian masses were considered less likely. Two days later, the patient returned with severe pelvic pain as well as fever and leukocytosis. Follow-up ultrasound showed enlargement of the mass and a tubo-ovarian abscess (TOA) was suspected. Ultrasound-guided transvaginal abscess drainage was performed with removal of purulent fluid. The case demonstrates that the radiological features of TOA may mimic those of adnexal cystic masses such as an endometrioma or hemorrhagic cyst. A complementary case is also included which demonstrates similar sonographic findings in a patient with endometrioma. In addition to sonographic imaging, a thorough clinical and laboratory evaluation is important in differentiating these entities. Furthermore, we provide a comprehensive discussion about imaging features of cystic ovarian mass on different imaging modalities.

Ultrasound-Guided Removal of an Infected Loose Body from the Quadriceps Muscle.

We present the case of a 35 year-old male with pain and swelling in his right thigh. By CT and sonography, an abscess was localized to the deep, anteromedial, mid-thigh within the quadriceps muscle, along with a 1.3 cm loose body. The infected loose body was removed under ultrasound guidance without complications.
