[en] We report on a 41-year-old woman with a chest wall desmoid tumour who was successfully treated with a computed tomography (CT)-guided steroid injection. She presented with a palpable mass in the right upper chest wall and was treated by surgical excision and postoperative radiation therapy due to recurrence of the mass at the surgical site. At 20 months after the second operation, a recurrent mass was again detected in the anterosuperior portion of the previous surgical site on CT. We performed a CT-guided steroid injection weekly for 4 weeks by applying a mixture of 3 mL of triamcinolone acetonide (40 mg/mL) and 3 mL of 1% Lidocaine, administering 4-6 mL of the mixture, to the lesion. Six months later, CT showed a marked decrease in the size of the mass.

[en] A 24-year-old man that had previously undergone a complete resection of a cervical paraganglioma presented with multiple well-defined intrapulmonary nodules on contrast-enhanced computed tomography. All of the nodules showed homogeneously intense enhancement. The largest nodule was a hot spot on F-18 fluorodeoxyglucose positron emission tomography. It was diagnosed as a paraganglioma using wedge resection via video-assisted thoracoscopic resection. Paragangliomas are rare neuroendocrine tumors and are exceedingly rare in the lung parenchyma. A few reports have described one or two intrapulmonary lesions, including primary tumors and metastases. We report a unique case of a multiple metastatic paraganglioma in the parenchyma of both lungs

[en] A pleural hemangioma is an extremely rare disease. Few studies have reported on the radiologic appearance of chest wall hemangioma, especially originating from the parietal pleura. We describe a 45 year old female patient with a soft tissue mass in the parietal pleura showing centripetal enhancement on dynamic CT. The patient underwent surgery and the pathologic examination confirmed the presence of a capillary hemangioma

[en] Pulmonary pleomorphic carcinoma is an uncommon malignant lesion of the lung. A chest radiograph of 53-year-old man who was suffering from a cough revealed a well-defined mass-like opacity with a broad base on the pleura at the apico-posterior segment of the right upper lobe of the lung. The subsequent chest computed tomography (CT) scan demonstrated an inhomogeneous enhancing mass with central low-attenuation in the right upper lobe. A lobectomy was performed and the mass was determined to be a pleomorphic carcinoma with visceral pleura invasion. Forty days after the operation, the patient complained of melena and an abdominal CT revealed an intraluminal and extraluminal protruding mass around the prepyloric antrum and duodenal bulb. The mass was removed by en-block surgery and diagnosed as metastatic pleomorphic carcinoma from the lung. Previous articles reported a median survival time of 3–10 months for pleomorphic carcinoma, but in this case, the patient has continued to survive, 11 years after surgery. Chest and abdominal CTs have revealed no evidence of tumor recurrence or metastasis
