Bronchogenic Carcinoma
Osaka Medical College, Dept. Radiology. Drs: Isamu Narabayashi, Kazunobu Nakata, Kojiro Tabuchi
49 yo male with mild temperature elevation and dull chest pain on the right side for three months. The pain gradually became worse. He began to have nausea and vomiting as well as the severe chest pain. He visited his Doctor two months ago. A tumour was found in his right upper lung field on CXR. Bronchoscopic examinations revealed bronchogenic carcinoma (squamous cell carcinoma). He was admitted to hospital for concurrent bronchial arterial infusion of CDDP with a systemic administration of VDS and radiation therapy.
Radiological Examinations
The CXR shows a tumour in the right upper lung field. The CT shows a tumour of about 10cm adjacent to the pleura posterior to the right S1 and S2 segments. The inner density of the tumour shadow is irregular with the central portion showing the least x-ray absorption.
MAA perfusion and SPECT
Perfusion lung scintigraphy indicates a large defect corresponding to the x-ray visualised site of the tumour. Otherwise no perfusion defects are seen.
|
Clinical Point: evaluation of the lung function excluding the tumour site to estimate post-operative lung function if surgery is indicated. |
Technegas planar and SPECT
|
General Comments: Technegas planar lung scintigraphy indicates a huge ventilation defect in the right upper lung. SPECT images also indicate the defect. There is a "hot spot" (excessive deposition of Technegas) at the left hilum. From the standpoint of the V/Q SPECT studies a surgical procedure was judged to be feasible, but the operation was abandoned because metastasis was found in the brain. |
