Magnetic Resonance Imaging of Intracranial Hemorrhage

Intramural duodenal hematoma: clinical course and imaging findings

Background

Intramural duodenal hematoma is a rare condition. Different imaging modalities are at hand for diagnosis.

Purpose

To identify patients with intramural duodenal hematoma and report imaging findings and clinical courses.

Material and Methods

Typical imaging patterns using ultrasound, computed tomography, and magnetic resonance imaging were carried out on 10 patients.

Results

The mean patient age was 7.5 years. The average disease duration was 13 months. Clinical signs of improvement were observed within 16 days. Residues were still detectable at long-term follow-up.

Conclusion

For patients with intramural duodenal wall hematoma, diagnosis should be considered early. Typical imaging findings should be known to ensure optimal treatment.

The role of cranial MRI in identifying patients suffering from child abuse and presenting with unexplained neurological findings

OBJECTIVE

The aim of this study was to demonstrate the usefulness of cerebral MRI to detect possible child abuse in children with unexplained neurologic findings.

METHOD

Between 1990 and 1997, 208 children were referred for suspected physical child abuse to the Child Protection Clinic of Ste-Justine Hospital, a tertiary care pediatric hospital. Among them, 39 children presented initially with neurological findings. For 27 of them, the CT Scan results prompted the diagnosis of child abuse. However, in 12 children, even if a CT-Scan was performed, the diagnosis and/or the mechanisms of the neurologic distress remained obscure. Investigation was completed with MRI study in those 12 cases.

RESULTS

MRI findings were diagnostic for physical abuse in eight cases. A diagnosis of child abuse was made in two more cases by a combination of MRI and skeletal survey findings. In one case, MRI was suggestive but the diagnosis of child abuse could not be confirmed. One case was misinterpreted as normal.

CONCLUSIONS

MRI is the test of choice to rule out child abuse when faced with a child presenting unexplained neurologic signs lasting for few days. The fact that MRI can better differentiate collections of different ages makes this imaging test particularly useful in identifying cases of child abuse. These results, however, always have to be integrated in a well conducted multidisciplinary clinical approach.

Subdural haematoma presenting with transient neurological deficits

OBJECTIVE

To stress that transient neurological deficits do not always imply transient cerebral ischaemia, and may be produced by subdural haematoma.

CLINICAL FEATURES

An 80-year-old man was seen for intermittent gait disturbance, with normal findings on initial examination. He was then admitted after the onset of a fixed neurological deficit which worsened. Subdural haematoma was diagnosed by computed tomography (CT). An 80-year-old woman was seen after she had experienced left hemisphere transient neurological deficits. A CT scan showed a left-sided subdural haematoma.

INTERVENTION AND OUTCOME

Both patients underwent successful surgery with complete resolution of their symptoms and signs.

CONCLUSION

Subdural haematoma is relatively common and must be considered in those with unexplained transient neurological deficits. Magnetic resonance imaging or CT are the diagnostic procedures of choice. Antiplatelet or anticoagulant therapy must not be instituted until subdural haematoma is excluded.
