Computed tomography and magnetic resonance imaging of desmoplastic fibroma with simultaneous manifestation in two unusual locations: a case report.

Introduction: Desmoplastic fibroma is an extremely rare primary benign bone tumor. It occurs most often in the mandible, followed by the femur and pelvis. To the best of our knowledge, fewer than 200 cases have been described in the published literature.

Bilateral inferior petrosal sinuses sampling in the routine investigation of Cushing's syndrome: a comparison with MRI.

Objective: Identifying the cause of Cushing's syndrome (CS) is a perplexing issue. Bilateral inferior petrosal sinuses sampling (BIPSS) is an invasive and elaborate but established procedure in distinguishing Cushing's disease (CD) from ectopic adrenocorticotropic hormone (ACTH) syndrome. We compare the diagnostic performance of BIPSS and MRI in detecting an ACTH-secreting source, and we suggest the diagnostic protocol that we found beneficial for the management of patients with CS.

Acute mediastinitis: spectrum of computed tomography findings.

The objective of this study was to describe CT findings and to determine the diagnostic value of CT in diagnosis of acute mediastinitis. CT findings were retrospectively studied in 40 patients with suspected acute mediastinitis, including 28 postoperative patients, five with acute descending necrotizing mediastinitis (ADNM), and seven with suspected post-traumatic perforation of the esophagus. Findings included increased attenuation of mediastinal fat (100%), localized mediastinal fluid collections (55%), free gas bubbles in the mediastinum (57.
