Pulmonary Langerhans cell histiocytosis is an interstitial lung disease that results from the accumulation of specific histiocytic cells in the lung. Spontaneous pneumothorax is a recognized feature of pulmonary Langerhans cell histiocytosis and results from destruction of lung parenchyma with associated cystic changes. We report on a 2-year-old boy with recurrent bilateral spontaneous pneumoth...

Fig. 2. The changes of myocardial ischaemia resulting from steal phenomenon were demonstrated by Thallium-201 myocardial perfusion scan (A-1: pre-embolisation, A-2: post-embolisation). Computed tomographic scan showed that the convoluted fistulous tract, originating from left circumflex coronary artery, passed through the subcarinal and left hilar region. These tortuous fistulae divided into mu...

The advantages of lung scanning in suspected pulmonary embolism are its diagnostic sensitivity, simplicity and safety. The ability to delineate regional pulmonary ischaemia, to quantitate its extent and to follow its response to therapy provides valuable clinical data available by no other simple means. The negative scan effectively excludes pulmonary embolism but, although certain of its featu...

A 50-year-old man presented with hematuria in July 2006. Abdominal computed tomography (CT) scan revealed a 12-cm right renal mass, and a right radical nephrectomy was carried out. Pathologic study revealed the clear cell type of renal cell carcinoma (RCC; Fuhrman grade II). Four months after nephrectomy, a chest CT revealed multiple pulmonary nodules (Figure 1A). With a clinical diagnosis of u...

A V/Q lung scan was obtained in a patient with LLL collapse who was receiving IPPV and PEEP. This revealed absent ventilation and hyperperfusion to the collapsed lobe. After a reduction in PEEP from 12 to 5 cm H O, a repeat V/Q scan showed a more even distribution of pulmonary perfusion. Arterial hypoxemia improved. (Chest 1991; 99:1034-36) D espite continuing controversy regarding the most app...

A 43-year-old woman had a pulmonary tumor detected by a computed tomographic (CT) scan during follow-up for breast cancer 15 years previously. The tumor showed a solid mass measuring 42 × 32 × 12 mm in extensive contact with the pleura of the apex of the left upper lobe. The edge of the tumor was relatively well-defined with an irregular shape, and a bubblelike area was seen within it. The long...

Giant cell tumor (GCT) is usually considered to be a benign entity. In rare cases, pulmonary metastases can be observed. This report documents the 99mTc-tetrofosmin scan findings of a conventional GCT of the femur and developed pulmonary nodules. The lung lesions were felt to be an example of benign metastases. According to our review, this is the first case in the literature demonstrating tetr...

Diffuse pulmonary deposition of [99mTc]methylene diphosphonate (MDP) as well as abnormalities characteristic of hypertrophic pulmonary osteoarthropathy have been observed in a patient with Pneumocystis carinii pneumonia (PCP). The findings of the bone scan together with those in the corresponding scintigraphy, and roentgenograms of the chest and skeletal structures are presented. Parallel rever...

Two patients with von Recklinghausen disease (neurofibromatosis type 1) were admitted to the hospital because of progressive heart failure. Both patients had prominent pulmonary hypertension revealed on cardiac catheterization. A lung perfusion scan did not show any gross defect. There were no underlying causes of pulmonary hypertension in either patient, such as chronic lung disease, congenita...
