  • Eosinophilic lung diseases are heterogenous disorder which are characterized by the presence of pulmonary symptoms or an abnormal chest radiograph accompanied by inflammatory cellular infiltrates in the airways and lung parenchyma which contain large numbers of eosinophils. The incidence of drug-induced pulmonary disorder is increasing, with at least 40 drug entities having been reported to cause this pulmonary disease. However, nonsteroidal anti-inflammatory drugs (NSAIDs) are rarely mentioned in the lists of drugs in published articles describing drug induced eosinophilic pneumonia. The following is a case of eosinophilic pneumonia that we believe was related to ibuprofen therapy.

  • Perfusion and ventilaion imagings of the lung are well established procedure for diagnosing pulmonary embolism, differentiation it from chronic obstructive lung disease, and making an early detection of chronic obstructive lung disease. To evaluate the usefulness of radioaerosol inhalation imaging (RII) in chronic obstructive lung disease, especially pulmonary emphysema, we analyzed RIIs of five normal adult non-smokers, five asymptomatic smokers (age 25-42 years with the mean 36), and 21 patients with pulmonry emphysema (age 59-78 years with the mean 67). Scintigrams were obtained with radioaerosol produced by a BARC nebulizer with 15 mCi of Tc-99m-phytate. Scanning was performed in the anterior, posterior, and lateral projections after five to 10-minute inhalation of the radioaerosol on sitting position. The scans were analyzed and correlated with the results of pulmonary function studies and chest radiographs. Also lung perfusion scan with $^{99m}Tc-MAA$ was performed in 12 patients. In five patients, we performed follow-up scans for the evaluation of the effects of a bronchodilator. Based on the X-ray findings and clinical symptoms, pulmonary emphysema was classified into four types: centrilobular (3 patients), panlobular (4 patients), intermediate (10 patients), and combined (4 patients). RII findings were patternized according to the type, extent, and intensity of the aerosol deposition in the central bronchial and bronchopulmonary system and lung parenchyma. 10 controls, normal five non-smokers and three asymptomatic smokers revealed homogeneous parenchymal deposition in the entire lung fields without central bronchial deposition. The remaining two of asymptomatic smokers revealed mild central airway deposition. The great majority of the patients showed either central (9/21) or combined type (10/21) of bronchopulmonary deposition and the remaining two patients peripheral bronchopulmonary deposition. Parenchymal aerosol deposition in pulmonary emphysema was diffuse (6/21), discrete(6/21), intermediate (3/21), or combined (6/21). In 12 patients studied also with perfusion scans, perfusion defects matched closely with ventilation defects in location and configuration. But the size of the ventilation defects was generally larger than the perfusion defects. In all four patients treated with bronchodilators, the follow-up study demonstrated decrease in abnormal of radioaerosol deposition in the central airway with improvement of ventilation defects. RII was useful technique for the evaluation of regional ventilatory abnormality and the effects of treatment with bronchodilators in pulmonary emphysema.

  • The pneumonic lungs of 51 pigs, from which the presence of pasteurella organisms was confirmed by bipolar staining, were examined pathologically. The numbers of pigs in each age group were 22 (43.1%) in 3-4 month group, 20 (39.2%) in 1-2 month group, 7 (13.7%) in 5-6 month group, and 2 (4.0%) in group of more than one year. The lungs of 16 pigs which were regarded as pasteurella pneumonia without any other manifestations were studied pathogically. Grossly, the affected lungs showed pulmonary edema, lobular consolidation and interlobular edema. Pigs over 3 months of age frequently showed chronic condition in which the entire lobe was involved as confluent pneumonia. In such pneumonic lungs, infarction and focal necrosis of the lung parenchyma and deposition of fibrinous exudate on the pleura were encountered. Histologically, the alveolar spaces were filled with fibrinous and leukocytic exudates. The interlobular septae showed marked edema and fibrinous exudate. The process of organization was frequently observed in chronic cases.

  • Pulmonary arteriovenous fistula is unusually congenital malformation consisting of an abnormal connection between a pulmonary artery and vein. It may appear as an isolated anomaly or with hereditary hemorrhagic telangiectasis. In the classic form, symptoms and signs are caused by the abnormal right to left shunt. since severe clinical symptoms such as paradoxical embolism, infection, and spontaneous rupture with massive bleeding may occur, surgical treatment is often indicated. Recently we have experienced a surgical treatment of pulmonary arteriovenous fistula in 54 years old housewife. She was admitted in May 1986 with recurrent hemoptysis for 1 month. On admission, the PaO2 was 65.2 mmHg without specific findings. Pulmonary arteriovenous fistula was confirmed by preoperative pulmonary arteriography. A well circumscribed cystic mass was noted in visceral subpleural and inferior lingular segment of left upper lobe. Left upper lobectomy was performed with good results. Histologically angiomatous dilatation of abnormal vessels embedded in lung parenchyma was noted. Postoperative PaO2 was 90 mmHg. Postoperative results were good.

  • Traumatic intrapulmonary glass foreign bodies that are missed on an initial examination can migrate and lead to severe complications. Here, we present a rare case of a traumatic intrapulmonary glass foreign body surgically removed by a direct pulmonary incision, which preserved the pulmonary parenchyma and avoided severe complications caused by migration.

  • Asthma is the most common disease of the lungs, and one that poses specific challenges for the physicians including radiologist. This article reviews for the clinical diagnosis, Radiologic features, and differential diagnosis of asthma, and outlines the radiologic features of the complications of asthma. Bronchial wall thickening and hyperinflation characterize the chest radiograph of the patients with asthma. On CT scan one may see airway wall thickening, thickened centrilobular structures, and focal or diffuse hyperlucency. Apparent bronchial dilatation may be seen, but the diagnosis of bronchiectasis should be made with caution. Quantification of changes in the airway wall and lung parenchyma may be valuable in understanding the mechanisms of asthma and in evaluating the effects of treatment. The challenge for the physician evaluating the images of a patient with asthma is to find complications.

  • A 2-year-old female donkey (Equus asinus) was euthanized in the Pathology Department of Firat University, Elazig, Turkey. Necropsy disclosed the presence of 7 hydatid cysts distributed throughout the lung parenchyma. One of those cysts represented the parasite material of the present study and was molecularly identified through sequencing of a fragment of cytochrome c oxidase subunit 1 (CO1) and nicotinamide adenine dinucleotide dehydrogenase subunit 1 (NADH1) gene, as Echinococcus equinus. The generated CO1 sequence supports the presence of the dominant haplotype as has been described in Europe and Africa. The NADH1 sequence was found similar to sequences reported in equids in Egypt and the United Kingdom. The molecular identification of E. equinus in a donkey is being reported for the first time in Turkey.

  • Tumor masses from a Bengal tiger (Panthera tigris) of 13 years in age raised at the natural farm in Yong-In were examined grossly and microscopically. The tumors were observed in the subcutis, lung, heart, liver, pancreas, kidney, cecum and spleen. Histologically the tumors were composed of solid anaplastic cells that formed mature or immature small blood vessels and invaded the adjacent parenchyma. The nuclei of the tumor cells were large, vacuolated, and round or ovoid, sometimes dense and ovoid or spindle. The mitotic figures were common and the boundaries between the cells were indistinct. The stroma was very sparse. A diagnosis of this case was made as hemangiosarcoma on the basis of gross and microscopic features.

  • Bronchogenic cysts are uncommon congenital anomalies and commonly located in the mediastinum or lung parenchyma. Bronchogenic cyst in cervical area is rare and in posterior pharyngeal area is exteremely rare. Clinically, it is usually asymptomatic and incidentally diagnosed. It is pathologically confirmed only when there are bronchial tissues such as pseudostratified ciliated columnar epithelium, smooth muscle cells, mucous gland and/or cartilage. Since it has potential for malignant transformation and complication, complete excision is essential. We report a case of bronchogenic cyst located in the retropharyngeal space with a review of literature.

  • Pulmonary arteriovenous fistula is a congenital vascular malformation originated from abnormalities of capillary development. Fistulas may develop only in the lung or may be associated with similar abnormalities of the skin, mucous membrane, and the other organs. It may occur with hereditary hemorrhagic telangietasia[Rendu-Osier-Weber syndrome]. Recently we have experienced a case of the pulmonary arteriovenous fistula associated with Schwannoma in 20 year old male man. Tennis ball sized bright reddish mass which was composed of variable sized vascular channels filled with blood clots was located in the just subpleural portion of left lower lobe. Left lower lobectomy was done. Microscopic findings showed variable sized numerous blood vessels embedding in the parenchyma. There was a thumb-tip sized brown nodular mass which was turned out to be Schwannoma at the left 7th thoracic paravertebral area.
