The sonographic features were reviewed in 30 cases of testicular trauma. Sonography correctly diagnosed testicular rupture in 12 surgically proven cases. Two additional cases of testicular rupture were diagnosed by sonography in patients who refused surgery. ⋯ There were no known false-negative diagnoses. Discrete fracture planes often are not identified by sonography in cases of testicular rupture. However, any alteration of the normal testicular echogenicity in traumatized patients suggests testicular rupture and requires surgery.

CT diagnosis of unsuspected pneumothorax after blunt abdominal trauma.
Review of abdominal CT scans for evaluation of blunt abdominal trauma yielded 35 cases of pneumothorax, 10 of which had not been diagnosed before CT by clinical examination or plain radiographs. Of the 10 cases initially diagnosed on CT, seven required tube thoracostomy for treatment of the pneumothorax. CT detection of pneumothorax is especially important if mechanical assisted ventilation or general anesthesia is used. Demonstration of pneumothorax requires viewing CT scans of the upper abdomen (lower thorax) at lung windows in addition to the usual soft-tissue windows.

Case ReportsCombined use of serum HCG and sonography in the diagnosis of ectopic pregnancy.
During an 18 month period, 320 patients were referred with clinical suspicion of an ectopic pregnancy. This study is based on 19 patients with ectopic pregnancy who had both a sonographic examination of the pelvis and determination of serum beta human chorionic gonadotropin (HCG) before surgery. ⋯ These are illustrated, and the sonographic criteria that have been used both for a positive diagnosis and for the exclusion of ectopic pregnancy in the past are analyzed. It is suggested that the accuracy of sonography can be increased by determining the serum HCG level on the day of the scan and by interpreting the findings with reference to the discriminatory HCG zone.
