Air trapping was found in approximately 50% of asymptomatic subjects. The frequency of air trapping increased with age, and its severity increased with age and smoking.

Ultrasound-guided vacuum-assisted percutaneous excision showed high effectiveness for the removal of benign breast masses. However, more attention should be given to certain lesions to increase the efficacy.

Sparganosis is human infestation by a larval form of an animal tapeworm, genus Spirometra. Human infestation is considered to be acquired by ingestion of water snakes, frogs, or drinking water contaminated with the larval stage of the tapeworm.'The frequent locations of infection in humans are subcutaneous tissue or skeletal muscle of the lower extremity, abdominal wall, abdominal viscera, chest, breast, scrotum, and brain.' The mammographic and sonographic findings in a case of breast sparganosis were reviewed. Sonographic feature in the breast was correlated with the sonography of the operatively extracted living worms from the breast and pathologic data. Mammography showed multiple, lobular, marginated, amorphic, solid masses without calcification. Sonography showed elongated, folded band-like hypoechoic structures in a heterogenous hyperechoic mass, which was proved to be the empty tunnel and the living worm with surrounding granuloma on pathologic examination. Hypoechoic band-like tracts in the mass suggested that tunnel where a worm had migrated because the extracted worm itself in saline solution appeared as a hyperechoic structure with sonography. This hypoechoic tunnel in the heterogenous hyperechoic mass is thought to be a reliable sonographic finding of breast sparganosis. CASE REPORTA 76-year-old woman was referred with a nontender, softly palpable mass in the right upper quadrant of the breast that had been present for 3

Shortening the duration of treatment for cervical tuberculous lymphadenitis.

ObjectiveThough a number of CT findings of bowel and mesenteric injuries in blunt abdominal trauma are described in literature, no studies on the specific CT signs of a transected bowel have been published. In the present study we describe the incidence and new CT signs of bowel transection in blunt abdominal trauma.Materials and MethodsWe investigated the incidence of bowel transection in 513 patients admitted for blunt abdominal trauma who underwent multidetector CT (MDCT). The MDCT findings of 8 patients with a surgically proven complete bowel transection were assessed retrospectively. We report novel CT signs that are unique for transection, such as complete cutoff sign (transection of bowel loop), Janus sign (abnormal dual bowel wall enhancement, both increased and decreased), and fecal spillage.ResultsThe incidence of bowel transection in blunt abdominal trauma was 1.56%. In eight cases of bowel transection, percentage of CT signs unique for bowel transection were as follows: complete cutoff in 8 (100%), Janus sign in 6 (100%, excluding duodenal injury), and fecal spillage in 2 (25%). The combination of complete cutoff and Janus sign were highly specific findings in patients with bowel transection.ConclusionComplete cut off and Janus sign are the unique CT findings to help detect bowel transection in blunt abdominal trauma and recognition of these findings enables an accurate and prompt diagnosis for emergency laparotomy leading to reduced mortality and morbidity.
