Traumatic injuries of the diaphragm are a known consequence of severe trauma, usually of the blunt type. Its incidence is increasing due to the rise in number and severity of accidents, especially car accidents. Diagnosing a traumatic diaphragmatic rupture is still a challenge for both radiologists and surgeons, with a delayed diagnosis in more than half of cases, with the consequent development of latent hernia. This hernia may manifest with symptoms varying from unspecific to bowel strangulation. We present the case of a patient with colonic obstruction secondary to a traumatic diaphragmatic hernia, with previous history of a penetrating thoracoabdominal trauma seven years before. Radiologic methods and signs for the diagnosis of this pathology are reviewed.

The changes of retroperitoneal lymph nodes in CT in a patient with AIDS are described. Differences with the compromise with M aviumintracellulare are discussed an also the differential diagnosis with other lymph node pathologies.
