摘要:

Hydatid disease is common in Turkey. Tension pneumothorax is rare, but it is an important complication of the hydatid cyst with significant morbidity and mortality. Tension hydropneumothorax secondary to the rupture of a hydatid cyst was detected in 5 of 185 spontaneous pneumothorax cases that were treated in the authors' clinic between 1992 and 1998. All patients were subjected to surgical treatment after urgent tube thoracostomy. No mortality or recurrence was observed at follow-ups of 9 to 24 months.

摘要:

The authors report an unusual case of hypersensitivity pneumonitis presenting on high-resolution CT as large and sharply defined nodular opacities caused by extensive bronchiolitis obliterans with organizing pneumonia. Many of the nodules were surrounded by a halo of ground-glass attenuation. To the authors' knowledge, this is the first time these features have been described in association with hypersensitivity pneumonitis.

摘要:

This case report details the initial radiographic findings of a patient with mixed connective-tissue disease who presented with significant hemoptysis. Several radiographic findings suggested mycetoma formation, prompting appropriate antibiotic therapy; however, the rapid resolution and subsequent reappearance of the lesion on serial images pointed toward a diagnosis of hemorrhage into a preexisting cavity. Chest radiographic and computed tomographic findings commonly described as pathognomonic for the diagnosis of mycetoma are, in fact, nonspecific and can be simulated by several other entities that result in intracavitary masses. Familiarity with these radiographic “mimickers” of mycetoma will aid in avoiding misdiagnosis and unnecessary or improper invasive interventions when the appropriate clinical history and course of disease are appreciated.

摘要:

A 59-year-old man who underwent chest radiography to exclude pneumonia showed an irregular nodular shadow in the left lower lung. A subsequent CT scan revealed an irregularly shaped soft-tissue mass consisting of two components: a peripheral round mass with spiculated margins and a well-circumscribed branching tubular opacity extending medially. Pathologically, the nodular lesion was found to be a poorly differentiated adenocarcinoma, and was contiguous with the central tubular opacity that represented the endobronchial polypoid growth of tumor from the periphery towards the hilum. The bronchial wall was found to be uninvolved by tumor. The centripetal pattern of endobronchial growth of a peripheral adenocarcinoma has not, to the authors' knowledge been described previously.

摘要:

The authors present the imaging findings in a 44-year-old woman with a rare intercostal hemangioma that originated from the connective tissue between the intercostal muscle and parietal pleura and protruded into the thoracic cavity. The contrast-enhanced computed tomography (CT) showed a markedly enhancing mass, whereas dynamic magnetic resonance (MR) images showed heterogeneous and strong enhancement with incomplete early eccentric enhancement peripherally followed by complete filling-in on delayed scans. The imaging features of CT and MR imaging of a hemangioma may be useful for proper preoperative diagnosis.

摘要:

The authors report the imaging characteristics of the anomalous origin of the left coronary artery from the pulmonary artery in a 612½-month-old male infant using electrocardiography, echocardiography, angiography, and electron-beam computed tomography. The patient presented with tachycardia, prolonged and interrupted feeding, failure to thrive, and myocardial infarction, and after diagnosis of the anomalous origin of the left coronary artery, survived the reimplantation of the left coronary artery directly to the ascending aorta. When reviewed 7 months after surgery, echocardiography showed improved left ventricular function and surface electrocardiography showed regression of pathologic Q waves in leads I, V4, V5, and V6.
