Multidetector computed tomography of spontaneous versus secondary pneumomediastinum in 89 patients: can multidetector computed tomography be used to reliably distinguish between the 2 entities?

Purpose: To analyze the multidetector computed tomography (MDCT) findings of spontaneous pneumomediastinum (PM) to determine whether MDCT can reliably differentiate spontaneous from secondary PM.

Materials And Methods: A retrospective clinical and chest MDCT analysis of all patients diagnosed with spontaneous PM over an 8-year period was performed. Radiologic comparison was undertaken with patients diagnosed with secondary PM from a central airways defect, esophageal rupture, or recent intervention in the airway or esophagus.

Borne identity: CT imaging of vascular infections.

Vascular infections present in a multitude of ways with computed tomography (CT) aiding in the diagnosis of many of the uncommon vascular infections, which are equally dangerous and carry severe life-threatening consequences if untreated from a delay in diagnosis. This pictorial review aims to discuss and illustrate the CT findings of the following vascular infections including aortitis, mycotic aneurysms, infective endocarditis, septic thrombophlebitis in the chest and abdomen, and Kawasaki disease. Recognition and prompt diagnosis of these uncommon vascular infections are critical to the initiation of the appropriate management and therapy.

Long-term outcome after chemoembolization and embolization of hepatic metastatic lesions from neuroendocrine tumors.

Objective: Hepatic artery chemoembolization and hepatic artery embolization (HAE) are accepted treatments of patients with hepatic metastasis from neuroendocrine tumors. Long-term outcome data are limited. We present our experience in the use of hepatic artery chemoembolization in the treatment of patients with hepatic metastasis from neuroendocrine tumors.
