Hydrogen peroxide is a commonly used oxidizing agent. If injected, it may result in morbidity via direct caustic injury, oxygen gas formation, and lipid peroxidation. We report a 40-year-old male patient who accidentally swallowed undiluted hydrogen peroxide (35%). The initial chest computed tomography scan showed no active lesions. He was admitted to the intensive care unit for conservative treatment. Fourteen days after treatment, uncontrolled fever and foul oder sputum occurred, which was not alleviated despite empirical antibiotics therapy. Findings on a chest computed tomography showed tracheo-esophageal fistula at the lower trachea and left main bronchus. He underwent surgical replacement surgery and was discharged without complication after 52 days of admission.

Diffuse interstitial lung disease(DILD) is a large group of heterogeneous diseases that diffusely involve the pulmonary connective tissues, principally subpleural, interlobular and alveolar wall portions. Terminology and classification of these diseases are not uniform, and the cause and the pathogenesis are unknown in many entities. It is generally accepted that the response to therapy is related to the relative degree of cellularity and fibrosis present, therefore a histologic evaluation of the relative extent and severity of these changes is required. We reviewed 52 cases of DILD from January 1990 to May 1995 diagnosed by open lung biopsy to reappraise classification and quantitative assessment of the histopathologic features. Differential histopathologic features between usual interstitial pneumonia(UIP) and nonspecific interstitial pneumonia(NIP) were examined with a correlation of HRCT findings and clinical findings. Among 52 cases of DILD, 18 cases(34.6%) were UIP, 6 cases(11.5%) were hypersensitivity pneumonia was NIP was 5 cases(9.6%), interstitial lung diseases associated with the connective tissue diseases were 5 cases(9.6%), inorganic dusts were 4 cases(7.7%), infections were 4 cases(7.7%), durgs were 2 cases(3.8%), acute interstitial pneumonia was 1 case(1.9%), sarcoidosis was 1 case(1.9%) in order of frequency plus 6 other cases(11.5%). UIP was the most frequent DILD in this study which seemed to be a criteria bias of patient selection on open lung biopsy. Quantitative assessment of histopathologic features was useful in the differential diagnosis of DILD and differentiation of UIP from NIP was possible based on histopathologic features and supported by HRCT. UIP disclosed a significantly high score of fibrotic changes, especially in the interstitial fibrosis, smooth muscle proliferation and honeycombing, otherwise NIP appeared relatively high score in inflammatory changes. Correlation between histopathologic scores and the clinical outcome after steroid therapy or no therapy in UIP was not evident.

Spinal cord tumors usually present themselves with severe pain without neurologic deficits during early stages. Cervical or thoracic spinal tumors can evoke anterior neck pain or chest pain without neurologic symptoms. As a result, when chest pain or anterior neck pain occurs initially, many physicians think its origin is a cardiac disorder such as angina. Eventually, during cardiac evaluation and treatment, myelopathy or radiculopathy develops to reveal spinal cord tumor. Even though it is rare, when anterior neck or chest pain is the presenting complaint, the possibility of spinal cord tumors should be considered. We report a case of spinal cord tumor with initial presentations of anginal chest pain and electrocardiographic myocardial ischemic changes (ST segment depression and T-wave inversion) in a 45 year old male patient who had no history of hypertension. It was later discovered that the cause was due to an A-V malformation.

Cerebral paragonimiasis ad cerebral cysticercosis are two notorious parasitic infestations of the brain in Korea, of which diagnoses were not clarified yet clinically. The authors experienced 25 such parasitic brain diseases with their characteristic CT findings, and it was assumed that computed cosmography(CT scan) is the procedure of choice for the diagnosis of these parasitic brain diseases.

For assessment of the feasibility of histopathological diagnosis on the basis of CT findings in suratentorial gliomas, 60 consecutive histologically proven cases were analysed. Benign astrocytomas(Kernohan's grade I, I-II, II) were 25, Oligodendrogliomas 6, malignant gliomas(Kernohan's grade III, III-IV, GM) 29 in number. Plain CT findings and degree of peritumoral edema were less significant than the patterns of contrast enhancement in predicting the histological malignancy. Calcification, if present, excluded the diagnosis of malignant gliomas. Combining the CT criteria of pattern of contrast enhancement, degree of peritumoral edema with angiographic signs of malignancy in addition to the clinical feature, a more confident histological diagnosis seemed allowable.
