To evaluate the reliability of MR imaging in tissue characterization and depiction of tumor boundaries, we performed MR-pathologic correlation using parosteally implanted VX-2 carcinoma in 17 rabbit thighs. T1-weighted, T2-weighted and Gd-DTPA enhanced T1-weighted axial images were obtained 10-30 days after tumor implantation. After the animals were killed, frozen and sectioned along the MR imaging planes, and histopathologic examinaton were done. For accurate MR-pathologic correlation, rabbits were fixed on the cardboard plate to minimize position change during the procedures. Tumor boundaries depicted on MR images were larger than those depicted on the specimen. Small tumors were surrounded by capsule-like loose connective tissue. Loose connective tissue became compact with tumor growth. This connective tissue showed high signal intensity on both T2-weighted and Gd-DTPA enhanced T1-weighted images. Muscle atrophy with fatty tissue accumulation around the tumor also contributed to the high signal intensity on MR images. Peritumoral edema and inflammatory reaction were not remarkable. Six of 8 cases with bone marrow fibrosis were detected on MR images. We concluded that peritumoral loose connective tissue and muscle atrophy exaggerated the size of experimentally induced malignant musculoskeletal tumors on MR images.

Mucocele of concha bullosa is rare and can be misdiagnosed as an intranasal tumor mass. We report a case ofmucopyocele of the concha bullosa.

We have relatively limited knowledge of symptomatic aspects of the postmenopause, rather than perimenopause. We tried to determine the factors associated with experiencing menopausal symptoms by Korean postmenopausal women. A total of 657 Korean women who underwent a natural menopause completed multiple questionnaires, which included questions regarding their attitudes to menopause, depressive symptoms, state anxiety, self-esteem, dyadic relationships, sociodemographic variables, and 11-item Menopause Rating Scale (MRS). Multiple regression analyses were performed to collectively examine the relative impact of each independent variable on the quality of life, as determined by the MRS. Decreased severity of menopausal symptoms was associated with more time spent in education, an employed status, a history of pregnancy, longer postmenopausal duration, positive attitudes to menopause, higher state anxiety, heightened self-esteem, and higher dyadic consensus. Increased severity of menopausal symptoms was also associated with absence of a partner, alcohol consumption, a history of hormone replacement therapy, a history of probable premenstrual dysphoric disorder, and increased severity of depressive symptoms. Sociodemographic characteristics, lifestyle factors, premenstrual dysphoric disorder, attitudes to menopause, a dyadic relationship with a partner, and the inner psychological status can be associated with the severity of menopause symptoms specifically in Korean postmenopausal women.

Renal oncocytoma is a rare, benign tumor, which is characterized by homogenous oncocytic cellular features without central necrosis or hemorrhage regardless of its size. Necrosis, although absence of which is emphasized in the most literatures, can rarely occur in oncocytoma. We reported here a case of renal oncocytoma in a 46-year old man, which tumor of his right kidney had exceptionally massive central necrosis and hemorrhage.

PURPOSE: To describe the MRI findings in the bronchial anthracofibrosis mimicking lung cancer on CT examination. MATERIALS AND METHODS: Ten patients, who showed CT findings mimicking lung cancer, were selected among fifty patients of bronchial anthracofibrosis proven by bronchoscopic biopsy, consisting of two men and eight women, ranging in age from 58 to 79 years old (average age, 68 years old). CT scan and MRI were performed in all patients(n=10). Percutaneous lung biopsy on mass was performed in one patient. MRI findings were analyzed with the emphasis on the signal intensity of the mass (n=4), collapsed lung (n=4) and lymph node (n=10) on axial T1 and T2-weighted images by two radiologists in consensus. No contrast enhancement was used in all cases. RESULTS: CT scan revealed mass(n=4), atelectasis with obstructive pneumonia(n=4) and bronchial wall thickening(n=2). All patients showed enlarged medistinal lymph nodes(n=10). The mass showed low signal intensity on T1WI and T2WI (n=4). The collapsed lung in patients with atelectasis indicated intermediate signal intensity on T1WI and low signal intensity on T2WI (n=4). Nine patients showed low signal intensity of lymph node on T1WI and T2WI, except one patient who showed central high signal intensity with peripheral rim of low signal intensity in right lower paratracheal lymph node on T2WI. CONCLUSION: Low signal intensity of a mass, collapsed lung, and lymph nodes on T2WI in anthracofibrosis patients may be helpful in differentiation of the lesion from lung cancer.

An exceedingly rare case of perforated early gastric cancer is reported. A 68-year-old man developed peritonitis due to perforation of early gastric cancer. An emergency radical operation was performed and was followed by an uneventful recovery. Histologic examination of the surgical specimen showed type III early gastric cancer composed of a signet ring cell carcinoma. Five years after surgery, the patients was alive with no evidence of tumor recurrence. The rarity of this complication in early gastric cancer is discussed, and a review of the literature is presented.
