PURPOSE: To evaluate the size of normal pons and cerebellum in vivo and the change in size according to age, and to compare those with measurement of the diseased pons and cerebellum. MATERIALS AND METHODS: 121 normal adults(M:F=54:67), 5 patients with OPCD and 19 patients with WallerJan degeneration were studied. The normal group was divided into 5 subgroups according to the age (ranged from 20 to 72 years). 1.5T GE Signa MR unit was used. On axial plane, the AP(A) and transverse(B) diameters of the pons, the size of the middle cerebellar peduncle(C), and transverse diameter of the posterior fossa(D) and the cerebellum(E) were measured. On midsagittal plane, the longitudinal(F) and AP(G) diameters of the basis pontis were measured. The ratios of E/D and F/G were calculated. The student t test was used for statistical analysis. RESULTS: C, E and F/G were 15.5mm+/-1.3, 99.8mm+/-4.3 and 1.63+/-.10, respectively. F/G, H/I, and H/J were larger in male(p<.01). All data of the pons showed no statistically significant differences among age groups. E of the seventh decades was shorter than that of the third decades(p<.05). C(12.7 mm+/-1.4) in OPCD and F/G(1. 81+/-.10) in Wallerian degeneration(p<.01) showed the most significant differences when they were compared to the normal. CONCLUSION: Although the cerebellum decreased in size with age, the pons maintained its size up to eighth' decades. The measurement of middle cerebellar peduncle on axial plane (C) and the ratio of basis pontis on midsagittal plane (F/G) were important in the evaluation of OPCD and WallerJan degeneration, respectively.

Twenty cases of polypoid lesions of the gallbladder were reviewed. Seven were benign lesions. Among them, there were 4 (20%) adenomas and 3 (15%) adenomatous hyperplasias. All of the benign lesions were less than 1 cm in diameter. Thirteen cases involved a carcinoma of the gallbladder, of which 92% were more than 1 cm in diameter, 76.9% were over 60 years of age, and 38.5% were associated with gallstones. The accuracy of the preoperative ultrasonographic diagnosis of the polypoid lesions of the gallbladder was 80%. The spread and the size of the tumor showed a close correlation. Therefore, the size of the tumor is a vital indicator for the treatment of polypoid lesions of the gallbladder; lesions between 0.6~1 cm in diameter should be followed up by ultrasonography. An operation may be considered if stones are present. Lesions bigger than 1 cm should be resected since malignancy can not be excluded.

OBJECTIVE: The aim of this study is to investigate the effect of tamoxifen on endometrial thickness in postmenopausal women taking adjuvant tamoxifen therapy for breast cancer after chemotherapy. METHODS: Fifty-eight tamoxifen-treated postmenopausal breast cancer patients underwent periodically transvaginal ultrasonography twice a year for 2 years and then once a year. We analyzed the correlation between the sonographic endometrial thickness and the duration of tamoxifen therapy. RESULTS: The mean endometrial thickness of breast cancer patients before tamoxifen therapy was 4.68 mm. But the mean endometrial thickness increased to 5.03 mm at 6 months, 5.21 mm at 12 months, after which it slightly declined to 5.13 mm at 18 months. And then it increased to 5.15 mm at 24 months, and 5.24 mm at 36 months. There was a significant increase in endometrial thickness after tamoxifen therapy compared with before tamoxifen therapy (p<0.05). Overall, proliferative endometrium was the most common histopathologic finding (5/14) in tamoxifen-treated postmenopausal women who had endometrial thickness >or=5 mm. No cases of endometrial cancer were detected. CONCLUSION: Significant increase in endometrial thickness with the duration of tamoxifen therapy in postmenopausal tamoxifen-treated patients may be associated with a high risk of endometrial pathologies in these patients.

Heterotopic mesenteric ossification is a very uncommon disorder that is characterized by new bone formation in the mesentery, which does not normally undergo ossification. A 52-year-old female experienced a small bowel obstruction 12 days after a segmental resection of the small bowel following a trauma. A laparotomy was performed 16 days after the initial operation, and a 2 cm hard mass was detected in the small bowel mesentery, with severe fibrous adhesions around the mass, involving the jejunum, which required resection. Postoperatively, the patient developed an intraabdominal abscess, followed by intestinal fistulation. The patient gradually recovered by conservative management, and left hospital 70 days after the first operation. Microscopic examination of the mass showed well oriented trabeculae of the osseous tissue, osteoid formation, with fine calcification and osteoblastic activity, but there was no formation of mature lamellar bone or clear evidence of the "zone phenomenon" that is classically described in heterotopic ossification. These findings appeared consistent with an early stage of heterotopic ossification. The etiology and pathogenesis are unknown; the heterotopic mesenteric ossification was thought to be associated with the trauma (intraabdominal surgery). The previous literature on heterotopic mesenteric ossification is reviewed, and a new case reported.

PURPOSE: Periampullary malignant tumors become symptomatic at an early stage because of their particular location. For this reason, radical resection is possible in the majority of cases. Periampullary tumors can be removed either by a local resection, as performed by Halsted in 1899, or by a radical pancreaticoduodenectomy, as performed by Whipple et al. in 1935. Both techniques have been used, and their respective places in the treatment of benign or malignant periampullary tumors has been the subject of constant debate. Therefore, we reviewed the cases of four patients who had undergone a transduodenal ampullectomy for an ampullary tumor which was confined to the ampulla of Vater. METHODS: The clinical records of 4 patients who undergone a transduodenal ampullectomy were reviewed. All patients were diagnosed as having an ampullary mass based on gastroduodenoscopy, endoscopic retrograde cholangiopancreatography, or both. Clinical presentation, comparison of pathologic findings of preoperative endoscopic biopsy, operative frozen section, final pathologic examination, complications, follow-up period, and recurrence were reviewed. RESULTS: The two men and the two women studied had a median age of 59.3 (range, 49 to 64 years). Among the four patients who underwent a transduodenal ampullectomy, an adenocarcinoma was found at final pathologic examination in two patients with preoperative diagnoses of a villotubular adenoma and a villous adenoma, respectively. The other two cases were diagnosed as tubular adenomas at final pathologic examination as they had been at the preoperative diagnosis. No evidence of disease was observed in any of the four patients on follow-up at 29 months, 30 months36 months, and 4 months. None of these patients had major complications in the immediate postoperative period, transient hyperamylasemia without clinical significance developed in two patients. CONCLUSION: The transduodenal ampullectomy is a valuable tool in the treatment of ampullary lesions. The result of local excision of the Vater for ampullary tumors appears satisfactory, and this procedure may be particularly indicated for benign tumors, as well as for older or high-risk patients whose malignant lesions are confined to the ampulla of Vater. However, the selection of this procedure required judicious decision making and precise technique and should involve an experienced team of pathologists and surgeons. As a result, for patients in whom it is indicated, a transduodenal ampullectomy is an alternative to the pancreaticoduodenectomy and has good long-term results.

As B.C.G. vaccination is being given extensively to uninfected children in this country. It has become important for pediatricians, general practitioners and public health people to differentiate natural conversion of response to tubercle bacilli from B.C.G. conversion. The authors have investigated this problem by studying 993 pupils in a primary school in Seoul. In our investigation, the difference between the convesion rate with 1/2,000 O.T. and 1/10,000 O.T. at various intervals after B.C.G. vaccination in the B.C.G.- converted group is statistically significant, whereas in the naturally converted group, the difference between the two groups is not statistically significant. There also is a difference in local reaction between the naturally converted group and the B.C.G.-converted group, although it is hard to distinguish with a single reaction whether it is due to natural conversion or to B.C.G. conversion. From both the results of our study and a some of the previous articles on this matter, the authors conclude that natural conversion to tuberculosis may be differentiated from B.C.G. conversion by using both 1/2,000 O.T. and 1/10,000 O.T. at the same time rather than using 1/2,000 O.T. alone, as practiced until now in this country, in order that the reaction may not be erroneous1y read as a naturally-converted positive reaction always.
