  • To compare the diagnostic yields and complication rates of transthoracic fine needle aspiration cytology(FNAC) and gun biopsy in the diagnosis of pulmonary mass, a retrospective review was performed in 125 cases. Under the fluoroscopic guide, FNAC was performed by 20G Chiba needle in 91 cases, core biopsy was done by 18.5 G vaccum needle attached with automated biopsy gun in 74 cases and both procedures were done together in 37 cases. Overall sensitivity was 88.4% in FNAC and 87.5% in gun biopsy. For malignant pulmonary tumors, correct type correlation with final diagnosis was obtained in 33(76.7%) out of 43 cases by FNAC and 30(75.0%) out of 40 cases by gun biopsy. For benign pulmonary lesions, there were correct type correlation in 14(35.0%) out of 40 cases by FNAC and 14(53.8%) out of 26 cases by gun biopsy. The complication was pneumothorax and hemoptysis. Pneumothorax occured in 11.1% of FNAC, 10.9% of gun biopsy and 10.9% of both technique, among which chest tube drainages were necessary in one patient by gun biopsy and in three patients by both technique. Although no significant difference of diagnositc accuracy and complication rate was found between FNAC and gun biopsy, gun biopsy was more helpful in the diagnosis of pulmonary benign lesions than FNAC.

  • Intrathoracic teratomas are unusual but intrapulmonary teratoma constitutes one of the rarities of medicine. A case is presented of pulmonary teratoma in which the initial clue was hemoptysis with intra-pulmonary mass. Left upper lobectomy was done. We would like to describe this case of extremely rare tumor.

  • Published data have shown that the levels of vascular endothelial growth factor (VEGF) and soluble VEGF receptor-1 (sVEGFR-1) in plasma and pleural effusion might be usefulness for lung cancer diagnosis. Here, we performed a prospective study to investigate the utility of VEGF and sVEGFR-1 in bronchoalveolar lavage fluid (BALF) for differential diagnosis of primary lung cancer. A total of 56 patients with solitary pulmonary massed by chest radiograph or CT screening were enrolled in this study. BALF and plasma samples were obtained from all patients and analyzed for VEGF and sVEGFR-1 using a commercially available sandwich ELISA kit. The results showed that the levels of VEGF in BALF were significantly higher in patients with a malignant pulmonary mass compared with patients with a benign mass (P < 0.001). However, no significant difference of sVEGFR-1 in BALF was found between malignant and non-malignant groups (P = 0.43). With a cut-off value of 214 pg/ml, VEGF showed a sensitivity and specificity of 81.8% and 84.2%, respectively, in predicting the malignant nature of a solitary pulmonary mass. Our study suggests that VEGF is significantly increased in BALF among patients with lung cancer than in benign diseases. Measurement of VEGF in BALF might be helpful for differential diagnosis of primary lung cancer.

  • Pulmonary sequestration and congenital cystic adenomatoid malformation are two infrequent congenital pulmonary diseases and the combination of these two entities is rare. We had experienced a 3 week old male patient with a pulmonary mass, who had been sufyerring from tachypnea and chest wall retraction after birth. The pulmonary mass was suspected as a congenital cystic adenomat id malformation by chest CT. And therefore, we performed urgent operation via standard thoracotomy incision. Upon a thoracotomy, there was an extrapleural mass with anomalous blood supply near the posterior diaphragm and multiple cystic lesions in right lower lobe. The two anomalous arteries arising from the thoracic aorta and one vein draining into the azygos vein were ligated. and then the extrapleural mass was removed and a right lower lobectomy was performed. Final histologic diagnosis was congenital cystic adenomatoid malformation associated with extralobar pulmonary sequestration. The patient was discharged without any problem.

  • A 34-year old man was admitted our hospital because he wished to evaluate the pulmonary mass that was incidentally detected on healthy examination. Bronchoscopy and chest CT showed endobronchial and peribronchial mass of the left lower lobe of the lung. Open thoracotomy and left lower lobectomy of the lung was done. Pulmonary mass was confirmed as a pulmonary inflammatory myofibroblastic tumor with bronchus invasion pathologically. Pulmonary inflammatory myofibroblastic tumor with bronchus invasion is a vary rare. Herein we report a case of pulmonary inflammatory myofibroblastic tumor with bronchus invasion.

  • A 4-year-old cat was referred for a suspected pulmonary mass. True diaphragmatic hernia presence was diagnosed via computed tomography (CT). There was a thin membrane covering the diaphragmatic defect. The membrane was thinner than the diaphragm. After contrast injection, the membrane was less enhanced than that of the normal diaphragm. The membrane was identified as a remnant of the parietal pleura. In addition, contrast-enhanced CT images provided clarity in viewing the herniated liver and falciform fat. A thinner membrane, covering the diaphragmatic defect, and attached to the thicker normal diaphragm, is considered a unique CT feature of true diaphragmatic hernia.

  • A case of inflammatory pseudotumor of the entire lung In a 61-ycar-old man is prcscntcd. The respiratory symptoms developed 2 months ago and progressed rapidly and the diagnosis of chronic pneumonia with ateletectasis of the entire lung, destroyed lung by tuberculosis and sepsis hAd to be ruled out The operative finding was different from our expectation. This case suggests that the Inflammatory pseudotumor can manifest as a whole lung-involving ass. Inflammatory pseudotumor is a nonneoplastic reactive pulmonary mass lesion that resembles tumor but shows little or no growth. Thc inflammatory pseudotufor usually present as a solitary round lung mass but in this casts progressed rapidly and destroyed the whole lung, which is rare. The patient was discharged with no problem and with outpatient followup.

  • This report describes the diagnostic radiographic and CT features of pleuropneumonia in a cat with wet type of feline infectious peritonitis (FIP). In a 1 year-old cat presented with respiratory distress, pulmonary mass, thickened pleural wall with mass-like structures, and a large amount of pleural effusion were identified on radiography, ultrasonography, and CT. About two months later, in addition to the pre-existing lesions, multiple nodules had developed on the intestine and left kidney. The cat was diagnosed with pleuropneumonia caused by FIP through histologic examination and immunohistochemistry. Pleuropneumonia is rarely reported in cats with FIP, and only one cat with non-effusive FIP had pyogranulomatous pneumonia as consolidated lung lobe. In the present case, pleuropneumonia was detected as multiple mass-like lesions on diagnostic imaging.

  • Inflammatory myofbroblastic tumor in the lung is a rare tumor. The etiology is not clear. This tumor in children is a benign tumor rarely presented with local invasiveness, recurrence, distant metastasis or malignant changes can occur. The complete surgical resection is chosen as the optimal management. A 12-years-old boy visited the outpatient clinic with a 4 cm sized pulmonary mass in left upper lung field. The patient underwent left upper lobectomy. Histopathologically, inflammatory myofibroblastic tumor was confirmed. The patient was discharged without any problems and there was no evidence of recurrence during 3 months follow-up.
