초록

악성 림프종은 흉부 CT에서 결절, 종양, 폐 경화, 간유리음영 등 다양한 폐질환으로 나타날 수 있으며 이러한 폐 병변은 다른 질환의 양상과 유사하여 진단에 어려움을 줄 수 있다. 본 증례는 호흡곤란과 발열을 주 증상으로 하는 67세 남성 환자로 해당 환자의 흉부 CT상 크기가 작은 다발성 결절이 양측에 미만성으로 나타나 혈행성 전이, 좁쌀 결핵 또는 진균 감염을 의심해 볼 수 있었다. 그러나 추가적으로 시행한 혈액 검사, 영상 검사 및 조직 생검 결과 폐를 침범한 미만성 큰 B세포 림프종이 진단되었다. 저자들은 폐의 좁쌀 결절로 발현한 매우 드문 림프종을 보고한다. 환자의 적절한 진단을 위해서는 환자의 병력, 신체 진찰, 혈액 검사 및 영상 소견의 포괄적인 평가가 필요하다.

Malignant lymphoma has various pulmonary manifestations on chest CT, including nodules, masses, areas of consolidation, and ground-glass opacity. These presentations can pose a diagnostic challenge, as they mimic other disease patterns. Herein, we report a case of diffuse large B-cell lymphoma (DLBCL) manifesting as miliary nodules in a 67-year-old male initially presenting with dyspnea and fever. Radiologic findings included diffuse, bilateral, multiple tiny nodules consistent with metastasis, miliary tuberculosis, and fungal infection. However, further investigations, including laboratory tests, imaging, and biopsies, led to the diagnosis of DLBCL involving the lungs. Herein we reported a rare case of lymphoma involvement of the lung presenting as miliary nodules. Accurate diagnosis relies on a comprehensive evaluation of the clinical history, physical features, laboratory test results, and imaging findings.
