11/14. Renal carcinoma with staghorn calculus, perinephric abscess, and xanthogranulomatous pyelonephritis in same kidney. Subcutaneous abscess of thigh as initial presentation.A case is reported of the simultaneous occurrence of renal carcinoma with staghorn calculus, perinephric abscess, and xanthogranulomatous pyelonephritis in the same kidney, with subcutaneous abscess of the thigh as the initial presentation. The coexistence of these diseases in the same kidney would seem to be important since they are frequently confused with each other.- - - - - - - - - - ranking = 1keywords = calculus (Clic here for more details about this article) |
12/14. Sonographic findings in perforation of the gallbladder.The sonographic findings in 13 patients with proven gallbladder perforation are described. Two patients were scanned immediately before and after gallbladder perforation. The sonographic findings before gallbladder perforation were gallbladder distension (one case) and gallbladder wall edema (one case). Pericholecystic collections develop after gallbladder perforation. These collections have a varied sonographic appearance ranging from anechoic to complex collections, and their internal characteristics seem to depend on the duration of the pericholecystic process. The residual gallbladder lumen or calculi can be identified within or peripheral to the pericholecystic process. The most acceptable mechanism for perforation of the gallbladder is: (1) impaction of a calculus in the cystic duct; (2) gallbladder distension due to secretion into its lumen by mucous glands located in the walls of the gallbladder; (3) vascular impairment of the gallbladder due to distension of the viscus; and (4) ischemia, necrosis, and perforation of the gallbladder wall. gallbladder perforation is a significant complication of acute cholecystitis associated with morbidity and mortality. Detection of this complication of acute cholecystitis by clinical means is difficult since the patient's symptoms are similar to those of uncomplicated acute cholecystitis. The inherent resolution of sonography offers an excellent display of the gallbladder and surrounding tissues allowing detection of pericholecystic collection secondary to gallbladder perforation.- - - - - - - - - - ranking = 0.2keywords = calculus (Clic here for more details about this article) |
13/14. laryngocele: an acquired condition.A 20-year-old female underwent excision of the submandibular gland for chronic sialadenitis and salivary calculus. She developed a wound hematoma which became infected. A wound abscess occurred which discharged spontaneously into the larynx and led to the formation of a combined laryngocele. This was excised, and the patient made a smooth recovery. There is no evidence of recurrence after two years.- - - - - - - - - - ranking = 0.2keywords = calculus (Clic here for more details about this article) |
