Lacunar cerebral infarct and nuclear magnetic resonance. A review of sixty cases.

A prospective series of 60 consecutive patients with lacunar cerebral infarcts (LI), studied using nuclear magnetic resonance (MR) and brain computerized tomography (CT), is presented. A significantly greater number of positive results (p less than 0.001) was observed in the MR (78%) in comparison with the CT scan (30%). In pure motor hemiparesis, the number of positive results obtained with MR was maximal (85%) and greater than with CT scan (35%; p less than 0.001). In pure sensory stroke, the positivity was 40% in MR and 20% in CT. In pontine and capsular topography, MR showed a greater sensitivity than CT scan (p less than 0.001). A significantly (p less than 0.001 greater number of silent infarcts were detected by MR (42%) than by CT scan (18.5%). Nowadays, MR is the complementary examination of choice in the topographic diagnosis of LI and should be carried out whenever possible in all patients presenting with this pathology.

Wallerian degeneration of the pyramidal tract in capsular infarction studied by magnetic resonance imaging.

Using magnetic resonance imaging, we studied 24 patients with ischemic infarction of the internal capsule. Magnetic resonance imaging detected wallerian degeneration of the pyramidal tract below the capsular lesion in 11 patients (45.8%); all 11 had clinical evidence of pyramidal tract damage. In six additional patients magnetic resonance imaging findings, present only on axial slices, were considered to indicate possible wallerian degeneration. When motor deficit was associated with posterior limb lesions, magnetic resonance imaging detected wallerian degeneration of the pyramidal tract in 78.6% (11) of 14 patients.

[Role of imaging in the exploration of the adrenal glands].

Currently, the major method of adrenal gland imaging is computed tomography. This method allows demonstration of normal adrenals and the diagnosis of adrenal masses (if these are greater than 1 cm in diameter). The examination should be directed by clinical signs and known laboratory investigations. Computed tomography is therefore the first line investigation to perform. Certain lesions may be better demonstrated by other methods: MRI and MIBG scintigraphy offer a greater specificity in the investigation of pheochromocytomas. In addition, scintigraphy can identify possible ectopic tumours or recurrences. Selective catheterisation of the adrenal veins allows aldosterone and cortisone secretions to be assayed. There remains the problem of the incidental finding of adrenal masses in either an asymptomatic patient or in the context of investigation of spread of a know cancer. These lesions may benefit from diagnostic percutaneous guided biopsy.
