Kagawa Medical University; Drs: Isao Sato, Kazue takahashi, Yoshihoro Nishiyama, Masatada Tanabe
Case history: 32 year old male had noted a sensation of shortness of breath and perioral numbness for the past two months. He has a history of exposure to an antifungal agent for the preceding several days immediately before the symptoms appeared. Brinkman index 250. Pulmonary function tests: VC 82.9%, RV/TLC 4% and FEV1 86.1%
Radiological Examinations
|
Comments: The plain CXR shows nothing abnormal. HRCT reveals lung regions of low absorption in the apices, but no abnormalities other wise. |
Technegas planar scintigraphy
Technegas SPECT
|
Clinical Point: Both Technegas planar and SPECT show abnormal deposition patterns more prominently than HRCT, probably suggesting the functional disturbance of the peripheral airways due to inhalation of chlorine gas. General Comments: Technegas planar images show an inhomogenous deposition of inhaled Technegas throughout both lungs but no hot spots were seen. A more marked inhomgeneity in deposition patterns as well as hot spots are revealed by SPECT. |
