[Contribution of magnetic resonance imaging in the early diagnosis of epidural metastasis].

BACKGROUND: Vertebral bone metastases represent the most frequently affected region within the skeleton. They are of important relevance because of the risk of medullar compression. The diagnosis of medullar canal invasion is of particular interest in order to prevent neurological dysfunction. A prospective study was carried out to detect the frequency and degree of invasion of the spine. METHODS: Twenty-eight patients were studied (13 males and 15 females), with a median age of 61 years (range 35-85), with cancer diagnosis and vertebral bone metastases, and local or radicular pain, without signs or symptoms suggesting myelopathy. Neurological, physical examination, radiological study (anteroposterior and lateral) and magnetic resonance imaging (MRI) study was performed in all patients to detect medullar canal invasion. RESULTS: Local pain was present in 43% of patients (n = 12), and radicular in 57.1% (n = 16). The most frequent radiologic vertebral involvement was thoracic (46.4%), with 71% of vertebral body collapse. MRI showed epidural space invasion in 75% of patients (n = 21), with a degree superior to 50% in 43%. CONCLUSIONS: The beginning of vertebral pain in a patient with cancer diagnosis, with evidence of bone invasion after radiological study, represents a major indicator to perform a MRI study to detect epidural involvement.

[The gastrointestinal concealment of illegal drugs].

The clinical, radiological and analytical aspects, and the complications observed in 16 cases of swallowing or insertion into the rectum of illicit drugs ("body-packing") are described. The drugs detected were heroin (6 cases), cocaine (5 cases) and cannabis (5 cases). In 15 cases abdominal plain X-rays were useful in the detection of the drug packages, their position and progression in the gastrointestinal tract and the presence of complications. The most valuable finding for radiologic diagnosis was the presence of a radiolucent halo surrounding the drug packages, or "double condom" sign, which was observed in 13/15 cases (87%). Urine analysis was positive for opiates or metabolites of cocaine in 7/9 cases (78%). One case presented acute heroin intoxication and three subjects gastric or intestinal obstruction requiring surgical treatment. In another case a packet, which had been retained in the stomach for five days, was extracted by upper gastrointestinal endoscopy using a Dormia basket with no complications.

Sacral pneumatocysts: CT appearance.

OBJECTIVE: CT findings of pneumatocyst of the sacrum have been evaluated. MATERIALS AND METHODS: Eight patients, six men and two women, with pneumatocysts of the sacrum were studied. Selective CT with 4 and 2 mm thickness was performed, and the intralesional attenuation coefficients were measured. RESULTS: All patients showed subchondral pneumatocysts of the sacrum with sclerotic margins related to the synovial portion of the sacroiliac joint. Intraarticular gas was found in six cases, and evidence of communication between the lesion and the joint was observed in two patients. Signs of bone degeneration were present in all cases. CONCLUSION: Pneumatocyst of the sacrum is a benign bone lesion associated with arthritic changes.
