CASE REPORT: We attend one 46-year-old male patient came for diagnostic evaluation of a rounded and radiolucent lesion in the transition of the subcondylar region and neck of the left mandible ramus incidentally found by a dentist. Computed tomography and magnetic resonance imaging were performed in medical radiology and a Stafne’s cyst was diagnosed in an atypical location. CONCLUSION: We emphasize that Stafne’s bone defect is a benign lesion, whose imaging diagnosis can be conclusive, avoiding unnecessary surgical procedures.展开更多

Typically, it is a slow growing lesion, and the differential diagnosis includes other benign and malignant endobronchial tumors. Case Report: We report a case of a 75-year-old female who complained of intermittent productive cough. Computed tomography of the thorax showed a solid nodule with lobulated contours in the right main bronchus and subtotal atelectasis of the right lower lobe. Bronchoscopy with biopsy confirmed the diagnosis of a bronchial fibroepithelial polyp. Conclusion: This case is illustrative and demonstrates the importance of imaging methods and of histopathological correlation for the accurate diagnosis of this benign treatable lesion.展开更多

It is postulated to have a predilection for female involvement and occurs mainly during late stages of the disease. Chest X-rays usually show small, diaphragmatic lungs. Occasional basal atelectasis may be present. Chest tomography usually shows reduced lung volumes with diaphragmatic elevation, occasional basal atelectasis, without severe pulmonary or pleuropulmonary disease. Shrinking lung can cause significant morbidity and occasional mortality. There is no definitive therapy, while corticosteroids may decrease symptoms and improve lung function in some patients. The objective of this study was to describe the main imaging findings in Shrinking Lung, an important pulmonary alteration in lupus patients. We highlight the characteristics observed on radiography and computed tomography, with an emphasis on computed tomography. It is important that every radiologist is prepared to recognize these findings and understand the possible clinical repercussions.展开更多
