A case of mucous gland adenoma arising from the main bronchus of the middle lobe of the right lung is reported, with review of related literatures. The patient, a 12 year-old Korean male, was admitted to Pusan National University Hospital with complaints of progressive coughing and dyspnea. Roentgenographic studies revealed a well defined mass involving the right middle lobe of the lung. With the impression of benign tumor, right middle lobectomy was performed. The gross specimen revealed a polypoid mass involving the main bronchus, measuring 4.5x 3.7 x 2.5cm. The cut surface of the mass revealed yellow-gray myxoid tissue. Histologically, the mass consisted of glandular structures filled with mucus, which proved to be acid one on histochemical study. The glandular lining was made up of a single layer of berign mucous cells, many of them being flattened.

The cryopathic hemolytic anemia is an autoimmune hemolytic anemia induced by cold antibody. Authors report a case of cryopathic hemolytic anemia confirmed by immunohematologic examination. A 22-year-old man was admitted at Kyung Hee Medical Center in March, 1994, with a past history of Kleinerfelter's syndrome and complained jaundice as well as dizziness. Direct antiglobulin test using polyvalent and anti-C3d monovalent antisera was positive, but was negative against anti-IgG, anti-IgA, and anti-IgM monovalent antisera. Cold agglutinin titer was as high as 1:1024 at 4 degrees C and anti-I specificity was confirmed by using cord bloods. The patient was not improved despite transfusion of washed red cells and administration of prednisolone, and on 16th day of hospitalization he manifested sudden episode of headache and loss of conscioussness, soon followed by death.

Image-guided localized, water-suppressed in vivo 1H MR spectroscopic studies were performed on the brain tumors in 3 patients. In all 3 patients, in vivo 1H MR spectra in brain neoplastic tissues revealed that the signal intensities of N-acetylaspartate (NAA) choline (Cho) resonances were decreased and increased, respectively, comparing with healthy normal tissue. A distinct lactate signal was identified in all three patients. A ratio that the observed metabolite alterations from localized, water-suppressed in vivo 1H MR spectroscopy can be useful as an index of brain tumors, and that the technique is clinically to highlight as one promising modalities in brain tumors for more accurate diagnosis.

Primary germ cell tumor of the testis is rare, which occupies 1 to 2% of all reported malignant male neoplasms. Combined primary germ cell tumor of the testis composed of embryonal carcinoma and seminoma is more rare tumor. The authors experienced a case of 50-year old male who presented with painless enlargement of right testicle. He has had radical orchiectomy and diagnosed by pathologically as combined germ cell tumor of testis. The testicle is measuring 180 gm in weight and 9×6×5 cm in dimension, and almostly replaced by tumor mass. Grossly the tumor is rubbery solid smooth tumor mass, with variegated cut surface with geographically outlined diffuse necrotic area. Histologically the tumor is composed of two components of tumor, which are solid growth pattern of large round to polyhedral cells with clear or granular cytoplasm and distinct cell border, and anastomosing glandular and papillary arrangement of anaplastic epithelial cells. The former corresponds to seminoma, and the latter to embryonal carcinoma. Each tumor lobule is separated by abundant fibrous stroma.

In vivo 1H MR spectroscopic studies were performed on the human brain in six normal volunteers. Some distinct proton metabolites, such as N-acetylaspartate (NAA), creatine/phosphoccreatine (Cr), choline/phosphocholine (Cho), myo-inostitol (Ins) and lipid (fat) were clearly identified in normal brain tissues. The signal intensity of NAA resonance is strongest. The standard ratios of metabolites from the normal brain tissues in specific regions were obtained for the references of further in vivo 1H MR spectroscopic studies. Our initial results suggest the in vivo 1H MR spectroscopy may provide more precise diagnosis on the basis of the metabolic informations on brain tissues. The unique ability of in vivo 1H MR spectroscopy to offer noninvasive information about tissue biochemistry in patients will stimulate its impact on clinical research and disease diagnosis.

PURPOSE: Pilocytic astrocytoma is a benign tumor predominantly arising from cerebellum in pediatric age. But it occasionally arises in supratentorium. We describe radiologic findings of supratentorial pilocytic astrocytoma. MATERIALS AND METHODS: Eleven CT and 7 MR examinations in 11 patients were retrospectively reviewed with attention to location, CT density, MR signal intensity, and degree and pattern of contrast enhancement on CT and MR. RESULTS: The tumors were located around the third ventricle (hypothalamus in three cases, optic chiasm in three cases) and in cerebral hemisphere (temporal lobe in three cases, frontal lobe in one case, thalamus in one case). On CT, the tumors were all sharply demarcated and rarely associated with edema. The tumors showed moderate to strong contrast enhancement. Necrosis appeared frequently in tumors around the third ventricle in contrast to frequent cyst formation in hemispheric masses. On MR, the tumors appeared hypo- or isointense on T1- weighted images and hyperintense on T2- weighted images. After administration of contrast agent, the tumors showed intense enhancement more than that of CT. CONCLUSION: The typical location and radiologic findings described above are helpful in the diagnosis of the supratentorial pilocytic astrocytoma.
