Ultrasonographic findings of appendiceal mucocele

The authors analyse the ultrasonographic findings of 10 cases of appendiceal mucocele retrospectively. In atotal of 10 cases, 6 cases showed only cystic masses with posterior reinforcement. The remaining 4 cases showedinternal echoes in the cystic masses. Differential diagnosis of mucocele from periappendiceal abscess is notpossible in ultrasound. The possibility of mucocele shold be considered if cystic mass in right lower quadrantabdomen is observed in ultrasound.

CT findings of tuberculous lymphadenitis in the abdominal cavity

Authors analyzed CT findings of 8 patients with tuberculous lymphadenitis and one case of tuberculous abscessdiagnosed surgically or clinically. The results were as follows; 1. Soft tissue density masses were noted in 8patients in paraaortic, mesenteric, peripancreatic, celiac, porta hepatis, and esophagogastric junction areas inorder of frequency, and these correspond to lylmph node groups of the same name. On contrast enhanced CT, rimenhancement with multilocular low dinsties indicating caseous necrosis were noted in 3 patients, ill defined lowdensities were seen in 3 patients, and no definite changes were noted in 2 patients. 2. Two or more lymph nodegroups were involved in 6 patients, and one lymph node group was involved in two patients. 3. A huge cystic masswith relatively irregular rim enhancement and small anount of solid component occupied nearly entire upper abdomenin 1 patient and this was confiremd as tuberculous abscess in peritoneum. 4. In 2 cases, bowel wall thickening wassuggested in cecum, ascending colon, and terminal ileum.

Ultrasonographic findings of gastric carcinoma

Stomach carcinoma is more common disease in korea than western contries. The reported ultrasonographicfindings of gastric carcinoma were thickening of gastric wall and “pseudokidney” sign. The auther analizedultrasonographic findings of 101 cases with gastric carcinoma who were performed ultrasonography and gastroscopyat Kyung Hee Universtiy Hospital from Oct. 1982 to Oct. 1985. The results were as followings; 1. Types of gastriccarcinoma were consisted with infiltrative type 68 cases, infiltrative type with ulceration 16 cases, polypoidtype with ulceration 1 cases, infiltrative and polypoid type 4 cases, linities plastica type 3 cases, lcerativetype 1 case and polypoid type 1 case. 2. Extent of the lesions were in body and antrum 45 cases, entire stomach 18cases, antrum 18 cases, body 12 cases, body and fundus 6 cases. 3. Ultrasonography was useful in demonstrating theextent of the tumor and the presence of materials elsewhere in abdoment.
