Abstract

Pneumonia is an infection of the lungs and respiratory system and can be classified by a variety of factors such as infectious agents, etiology, infection area, and other criteria. From a 46-year-old male, who was suspected of being infected with atypical pathogen pneumonia and underwent such tests as serological testing, examination of sputum, urine examination, parasite examination, bronchoscopy, needle biopsy and so on, no significant abnormality was found. This patient also showed no specific symptoms like auscultatory abnormalities, high fever, nonproductive cough, muscle stiffness, sputum production, dyspnea. Prescription of broad-spectrum oral antibiotics and ant-parasitic didn't seem to be effective against bacterial and atypical pathogen. The patient's condition alternately repeated between natural cure and recurrence. The average healing process during which scarring, nodule recurrence and disappearance on the lungs happened was about 20 days. Chest radiography and chest high resolution computerized tomographic scans(HRCT scan) was performed to depict parenchymal aberrations and demarcate the extent and distribution of atypical pathogen pneumonia. As a result, chest radiography did not show the specific symptoms, whereas areas of opacity (seen as white) which represent consolidation were revealed in chest HRCT scan. This indicates that only chest radiography is not that useful for early diagnosis of atypical pathogen pneumonia in patients, since it can't show exactly what the symptom is because of the barriers such as diaphragm, liver, and spine. Therefore, it is desirable that chest HRCT should be used in the diagnosis to compare with the results of chest radiography. Here, report with literature investigations the case of recurrent atypical pathogen pneumonia.

폐렴은 호흡기계의 감염이고 원인균, 병인, 침범부위, 그 밖의 여러 가지 상황에 따라서 다양하게 분류된다. 비정형 병원균주 페렴으로 의심되어 내원한 46세의 남자 환자에서 이학학적 소견이나 혈액검사, 객담도말검사, 소변검사, 기생충검사, 기관지내시경검사, 침생검 등에서 특이할만한 원인균을 찾지 못했으며, 청진이상, 고열, 고혈압, 객담, 호흡곤란 등의 증상 또한 보이지 않았다. 세균성 또는 비정형 병원균의 광범위치료 항생제 복용이나 기생충제제를 복용하였으나 재발되었으며, 자연치유 및 재발이 반복되며 호전되었다. 반흔을 남기며 호전되고 새로운 부위에 결절이 재발하기를 반복하면서 서서히 없어지는 기간은 평균 20일 정도였다. 재발 이후 흉부엑스선 촬영과 흉부 고해상 전산화단층촬영을 추적 검사한 결과 흉부엑스선 촬영에서는 특이한 징후를 관찰하지 못했으나 고해상 전산화단층촬영에서는 병변이 호전되어가고 새로운 부위에 재발되는 모습을 관찰할 수가 있었다. 양측 하부 폐에 재발성 경과를 취한 비정형병원균주 폐렴이 의심되는 환자의 경우, 흉부엑스선 촬영 소견은 횡격막이나 간(Liver), 척추 등에 의해 숨기 때문에 추적검사로서 도움을 주는 데는 한계가 있으며, 흉부 고해상 전산화단층촬영 검사를 하여 비교하는 것이 바람직하다. 저자는 재발성 경과를 취한 비정형 병원균주 폐렴1예에 대한 문헌고찰과 함께 보고한다.
