CONTEXT: Stafne's bone defect is a benign lesion appearing on the image as a round radiolucent lesion within a cortical defect on the mandible. 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.
Context: Bronchial fibroepithelial polyp is a very rare benign endobronchial tumor. 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.
Shrinking lung refers to a rare complication of systemic lupus erythematosus and is characterized by unexplained dyspnea, a restrictive pattern in lung function tests, and elevation of the diaphragmatic hemicuples. 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.
Context: Bronchopulmonary sequestration is defined as a congenital malformation in which a portion of lung tissue does not communicate with the normal bronchial tree and the pulmonary arteries. Case Report: We present a case of a 35-year-old male complaining of left lower back pain and with a mass in the left thoracoabdominal transition. Imaging studies have suggested a pulmonary sequestration and its diagnosis was confirmed by histopathological study. Conclusion: Diaphragmatic extralobar pulmonary sequestration is a rare anomaly whose radiological diagnosis is difficult. This case is illustrative and demonstrates the importance of imaging methods to the correct diagnosis and effective treatment.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
