Scintimammography: a pictorial review of the variable normal, post surgical and pathological appearances.

Scintimammography has a high specificity and sensitivity for the detection of primary and metastatic breast carcinoma and in the evaluation of the postoperative breast. This review highlights the spectrum of pathological features as well as the normal postoperative and postreconstruction changes and the variable normal appearances that may be encountered with this technique.

Pictorial review. Ultrasound of the testis.

Ultrasound examination is the primary imaging investigation used in initial evaluation of the symptomatic testis. In this review the ultrasound appearances of a range of testicular lesions are demonstrated. Particular attention is given to the subject of testicular microlithiasis and its link with germ-cell neoplasia, and also to the sonographic features of epidermoid cysts that may allow testis-sparing surgery.

Ultrasound features of folded lung.

The ultrasound features of folded lung (rounded atelectasis) have not been described previously. The US findings of folded lung in fourteen patients and correlation with computed tomography are presented. The principal US findings were a pleurally based 'mass' and thickening of the adjacent pleura and extrapleural fat. A highly echogenic line extending from the pleural surface into the mass was seen in 12 patients (86%). We believe this finding corresponds to the scarred invaginated pleura as demonstrated in pathological studies of this condition.

Removal of a submandibular duct calculus with a vascular snare.

Conventional management of calculi in the distal portion of the submandibular duct involves surgery under general anaesthesia. We report here a patient whose calculus was successfully removed non-surgically as an outpatient with a vascular snare.
