RESUMO

We present the first imaging report of perforated appendicitis in an umbilical hernia. Computed tomography demonstrated a gas-forming abscess within an umbilical hernia and the cecum was found inside the hernial sac, with an inner relation to the abscess. Computed tomographic findings suggested appendicitis as possible diagnosis, which was confirmed at surgery. Physicians must consider appendicitis within the differential diagnosis of an abdominal abscess located near to the cecum, even at an unexpected location.

RESUMO

PURPOSE: To analyze the utility of helical computed tomography (CT) in the diagnosis of suspected upper esophageal foreign bodies. MATERIAL AND METHODS: A prospective study was performed on 36 patients (26 F, 10 M, mean age 70 years) with a history of foreign body impaction. All had negative findings at indirect laryngoscopy. Radiologic assessment included unenhanced helical CT and a barium contrast study. Patients with positive findings were taken to esophagoscopy. All patients had a posterior clinical surveillance. RESULTS: Twenty patients had both normal CT and barium study and satisfactory clinical outcome. In 12 patients a foreign body was noted in the cervical esophagus by CT, barium study, and endoscopy. In one patient a fish bone was detected by CT (and not by barium) confirmed with esophagoscopy. Another patient had a fish bone esophageal perforation which was observed only by CT and confirmed at surgery. Two patients with normal barium and endoscopy presented a false-positive CT result. CONCLUSION: Barium swallow is currently the first radiologic study, but may involve a risk of aspiration and can impede a subsequent esophagoscopy. Esophagoscopy is an invasive technique with a certain risk of serious complications that can be avoided with a satisfactory radiologic assessment. CT is easy, fast, has 100% sensitivity and is therefore the first choice technique for diagnosing suspected upper esophageal foreign bodies not expected to be visible on plain radiographs.

RESUMO

La rotura bronquial es una complicación infrecuente pero potencialmente grave en el traumatismo torácico cerrado, con una mortalidad asociada del 30 por ciento. En las últimas décadas se está presenciando un incremento en su incidencia paralelamente al desarrollo de los medios de transporte. El 80 por ciento de las lesiones se localizan a 2,5 cm de la carina. El diagnóstico está basado en las manifestaciones clínicas, hallazgos radiológicos y en la broncoscopia. El enfisema subcutáneo y la insuficiencia respiratoria son los síntomas más frecuentes. A escala radiológica destaca la presencia de neumotórax, neumomediastino o ambos. La broncoscopia es el método diagnóstico de elección y se debe realizar de forma temprana. El tratamiento es el restablecimiento de la continuidad anatómica del árbol traqueobronquial mediante la reparación quirúrgica de la lesión, tan pronto como sea posible, si ésta es mayor de un tercio de la circunferencia y/o el neumotórax no se resuelve con dos drenajes torácicos. Es muy importante que este tipo de lesión sea reconocida y tratada de forma temprana, tanto para restaurar con éxito la función pulmonar, como para evitar las complicaciones asociadas con el retraso diagnóstico y terapéutico. No obstante, los hallazgos iniciales son a menudo inespecíficos, y requieren un alto índice de sospecha, por lo que en un porcentaje elevado de pacientes el diagnóstico es tardío. (AU)

RESUMO

In closed chest trauma, bronchial rupture is an unusual but potentially serious complication, with an associated mortality rate of 30%. Recent decades have seen an increase in incidence parallel to greater use of transport. Eighty percent of injuries are located 2.5 cm from the carina. Diagnosis is based on clinical signs, imaging and bronchoscopy. Subcutaneous emphysema and respiratory insufficiency are the most common findings. Images show the presence of pneumothorax, pneumomediastinum or both. Bronchoscopy is the diagnostic method of choice and must be performed early. Treatment consists of reestablishing anatomical continuity of the tracheobronchial tree by surgical repair if the lesion affects more than a third of the circumference and/or pneumothorax is not resolved after two chest drainages. This type of injury should be recognized and treated early, both to restore lung function and to prevent associated complications caused by delay. However, initial findings are seldom specific, requiring the physician to display a high degree of suspicion and explaining why diagnosis often comes late.

RESUMO

PURPOSE: To report on an exceptional case of spontaneous, idiopathic, unilateral adrenal gland rupture that caused massive retroperitoneal hemorrhage. METHODS AND RESULTS: US and CT were performed in a patient who presented with acute abdominal pain. Urgent adrenalectomy was required to prevent the blood loss from continuing. The CT findings were correlated with the histological findings. CONCLUSION: CT proved to be an accurate imaging modality by which to diagnose adrenal hemorrhage. The absence of irregular tissue enhancement showed that neoplasia was not the underlying cause of the hematoma.

RESUMO

A case of aortoesophageal fistula (AEF) is reported in a patient with esophageal bleeding resulting from ingestion of a foreign body. CT showed a saccular aneurysm in close proximity to the esophageal lumen at the level of the bleeding site. AEF has not previously been described on CT.

RESUMO

This paper presents the first description of a ruptured aneurysm of an aberrant right subclavian artery. CT clearly demonstrated the vascular malformation as well as the existence of a bilateral hemothorax.
