CT findings of sternal fracture.

UNLABELLED: A retrospective study of blunt chest injuries due to motor vehicle accidents between the years 1990 and 1995 found 9 cases of sternal fracture that had both lateral plain film and thoracic axial CT scans performed. Plain film identified 8 of the 9 fractured sternums. CT scanning was only able to identify 6 sternal fractures. Secondary signs of sternal fracture were only seen in 5 of 9 patients, 3 had retrosternal haematomas and 2 had haematoma of the mediastinum. CONCLUSIONS: (1) plain film is still superior to Axial CT scanning for identification of sternal fracture; (2) retrosternal haematoma, although a specific sign for sternal fracture has low sensitivity (3/9); (3) mediastinal haematoma, a poorly specific sign for sternal fracture also demonstrated low sensitivity.

Blunt head trauma: comparison of various weapons with intracranial injury and neurologic outcome.

The weapons used in blunt head trauma cases were identified to determine if a particular weapon was associated with a specific type of intracranial injury or a poorer neurologic outcome. A consecutive sample of 178 patients was examined. Forty-seven percent of patients beaten with baseball bats and 63% of patients beaten with fists had positive computed tomographic (CT) findings. Twenty five percent of patients beaten with bats and 48% of those beaten with fists had poor neurologic outcomes (p < 0.056). Of those with positive CT findings, 30% of patients beaten with bats and 59% of patients beaten with fists had a poor outcome (p = 0.511). No weapon was associated with a particular intracranial injury. Of assault victims who survive an attack and require admission to the hospital, those beaten with bats are less likely to have significant neurologic dysfunction upon hospital discharge than those beaten with fists.

Plain film radiologic examination of the abdomen.

The plain film of the abdomen usually is the first radiographic examination ordered to evaluate the abdomen in the ICU patient. It is inexpensive, universally available and may be done at the bedside in the ICU. This article details and describes what to look for when interpreting a plain radiograph of the abdomen.

Resident interpretation of emergency computed tomographic scans.

Our busy, urban emergency room is staffed by radiology residents after working hours. To determine the accuracy of our residents' interpretations of emergency cranial computed tomographic (CT) scans, the authors reviewed the preliminary reports of our residents for a two-month period. A total of 289 cranial CT scans were retrospectively reviewed and the resident interpretation judged acceptable, minor error, moderate error, or major error. Six of 289 neurologic examinations (2%) had moderate (4) or major (2) errors. The mistakes all involved misinterpretation of cerebral hemorrhage. The 98% accuracy in interpretation of cranial CT is higher than the accuracy reported with emergency plain film (PF) interpretation.

Lung disorders due to drug abuse.

Drug-related diseases of the lungs have been noted with increasing frequency in urban patients. These entities are also being seen in smaller urban and suburban settings, however. The spectrum of pathology is also changing coincident with the marked increase in crack cocaine use. The incidence of abnormal chest radiographs in cocaine users admitted with pulmonary complaints has ranged from 12% to 55%. Findings have included focal air space disease, atelectasis, pneumothorax, pneumomediastinum, and pulmonary edema. Pulmonary complications related to injections of illicit drugs have included pulmonary infection, pulmonary edema, particulate embolism, and talcosis. The "pocket shot" places the patient at risk for a unique set of complications. Radiologists should be aware of this wide spectrum of pulmonary disease that may be related to this increasingly frequent social problem.

The groin hit: complications of intravenous drug abuse.

We are seeing an increased number of complications in intravenous drug abusers who resort to injecting the groin for vascular access (the "groin hit"). Vascular complications include venous thrombosis, arteriovenous fistula, mycotic aneurysm, ruptured pseudoaneurysm, and dissecting hematoma. Soft tissue complications include cellulitis and abscess. The latter may dissect into the extraperitoneal space. Skeletal complications include osteomyelitis and septic arthritis. This paper illustrates the radiographic spectrum of these complications. An algorithm will illustrate the radiographic evaluation of a groin mass in a drug addict.

Cocaine abuse: neurovascular complications.

In a review of the records of 3,712 drug abusers, 13 patients were identified with neurologic deficits attributable to the use of cocaine. Ischemic manifestations were the most frequent, occurring in seven (54%) patients, with a mean age of 34.2 years. Three (23%) patients had subarachnoid hemorrhage, and three (23%) had intracerebral hemorrhage. Three patients from other institutions were included in the analysis, for a total of 16 patients, (eight with cerebral ischemia, four with subarachnoid hemorrhage, and four with intracerebral hemorrhage). Of the six patients with head computed tomographic findings of cerebral infarction, five had subcortical infarcts. Two of the four patients who presented with a subarachnoid hemorrhage had a congenital intracranial aneurysm. One of the four patients with an intracerebral hemorrhage had an underlying arteriovenous malformation. The mechanism through which these complications occur is not completely understood. Factors that may play a role include the acute hypertensive response that occurs with cocaine use as well as disordered neurovascular control.

Post-ERCP pancreatitis: association with urographic visualization during ERCP.

To investigate the possible association of urographic visualization and acinarization of contrast material with postprocedure pancreatitis, 140 consecutive endoscopic retrograde cholangiopancreatograms (ERCP) with pancreatic duct filling were reviewed. Urographic visualization was identified in 29 patients (21%); pancreatitis developed in 13 of these patients (45%). Pancreatitis occurred in five of 111 patients (4%) without urographic visualization. Of 19 patients who demonstrated both acinarization and urographic visualization, ten (53%) had postprocedure pancreatitis. Twenty-six patients exhibited acinarization without urographic visualization; one (4%) had pancreatitis. Urographic visualization during ERCP is probably more common than generally recognized and indicates patients who are at high risk for postprocedure pancreatitis. Although acinarization accompanied by urographic visualization is associated with a high risk of pancreatitis, acinarization alone was not associated with this complication in this study. Detection of renal opacification during ERCP requires close scrutiny of films is best accomplished on overhead radiographs.
