The impact of restricted diet on brain function using BOLD-fMRI.

We investigated the effect of a restricted diet model on activity in the human motor cortex using functional magnetic resonance imaging (fMRI). Two series of blood oxygenation level-dependent (BOLD)-fMRI measurements were made in healthy subjects performing simple motor tasks using their right hands. The first series was done 5-10 days prior to the restricted diet schedule (controls), and the second series was performed after 25-28 days of restricted diet, in the form of a religious fast (Ramadan). The size and intensity of the activated area in the motor cortex increased during the time of restricted diet versus the controls. We conclude that restricted diet has a significant effect on cerebral activity, as shown by BOLD-fMRI, although the exact relationship between the images and neuronal activity due to the restricted diet is still to be determined.

[Neuroimaging findings in eclamptic patients still symptomatic after 24 hours: a descriptive study about 19 cases].

OBJECTIVE: To describe the neuroimaging findings in eclamptic patients still symptomatic after 24 hours. PATIENTS AND METHODS: All parturients consecutively admitted over a 12-month period for eclampsia and presenting with neurological disorders (coma, focal neurological abnormalities, and eye sight disturbance) underwent cerebral CT-scan and/or MRI. RESULTS: Nineteen women were studied, and all had abnormal neuroradiological findings. The CT-scan was normal in three cases. Cerebral oedema was the predominant lesion (14 cases). It was localized in the parietal or occipital area (12 cases), paraventricular area (1 case), or was diffuse (1 case). Diffusion weighted MRI was performed in four cases and showed cytotoxic cerebral oedema in one case. There were three cases of cerebral venous thrombosis and two cases of intracerebral haemorrhage. CONCLUSION: Various neuroradiological lesions can be observed in eclamptic patients. A localized cerebral oedema is the most frequent. Diffusion weighted MRI should be systematically done when neurological disorders persist.

[Milk of calcium in a renal cyst: a case report].

Milk of calcium in a renal cyst is a rare condition. The authors report a case evaluated by ultrasonography, computed tomography (CT) and magnetic resonance imaging (MRI). A 58 year - old women presented with diffuse abdominal pain. Ultrasonography showed a left upper pole cystic lesion with echogenic component in the dependent portion causing shadowing. CT showed a cyst with layering milk of calcium. On MRI, the milk of calcium sediment had low signal intensity on T1 and T2 weighted images.

[Patent omphalomesenteric duct (a case report)].

PURPOSE: To report a rare case of patent omphalo-mesenteric duct and discuss the pathogenesis, clinical and radiological findings of this pathology. CASE REPORT: A two-month-old infant presented with umbilical liquid production since birth. Local examination showed an inflammatory umbilical tumefaction. Catheterization and injection of contrast material through the canal evidenced a communication with the gut, consistent with a patent omphalo-mesenteric duct. DISCUSSION: Persistent omphalo-mesenteric duct is a rare affection. Diagnostis is based on clinical and radiological findings. Clinical findings may be atypical in some cases. Complications are severe and include prolapsus, occlusion, ulcus, haemorrhage and perforation. CONCLUSION: Diagnostis of patent omphalo-mesenteric duct must be precocious to avoid complications.

[Sural false aneurysm disclosing the presence of Behçet's disease].

The authors report the case of a 35 year old patient that presented acutely with a false aneurysm of the tibioperoneal trunk diagnosed at Doppler US and CT angiography. Behçet's disease was considered because of a prior history of recurrent phlebitis, the presence of bipolar aphthae and a biological inflammatory syndrome. This case is of interest for two reasons: first, the atypical location of the false aneurysm, and second, the value of less invasive imaging techniques, namely Doppler US and CT angiography.

[CT and MRI features of spinal hydatidosis. A report of 8 cases].

PURPOSE: Hydatidosis affects the bone in 0.5 to 2% of cases, with 44% of these cases involving the spine. We report 8 cases of vertebral involvement evaluated by CT and/or MRI. Materials and Methods. This retrospective study from January 1996 to August 2000 included seven patients (5 men and 3 women) aged between 28 and 65 years old. The mean age was 45 years old. Five patients underwent CT scan (one by CT-myelography). MRI was available in 4 cases. RESULTS: Imaging showed multicystic bony lesions. Thoracic involvement was present in 4 cases, lumbar involvement in 2 cases, and sacral involvement in 2 cases. The process involved 2 adjacent vertebrae in 4 cases at the thoracic and lumbar levels and the entire sacrum in the other cases. Only one case of vertebral collapse was noted, but extension into the spinal canal was noted in all cases. Other sites of involvement were also noted, especially in adjacent soft tissues, liver and spleen. CONCLUSION: The presence of multicystic vertebral lesions with involvement of adjacent soft tissues and/or distant organs should raise the possibility of spinal hydatidosis in endemic countries.

[An unusual cerebral hydatid cyst].

Hydatid cysts of the brain are very rare. Typically, the cyst is large, spherical, with sharply defined borders. Its may calcify, and there is no surrounding edema and no rim enhancement. Sometimes, one side of the cyst wall is very close to the calvarium, with thinning of the internal table. We report a case of hydatid cyst of the brain with particular scanographic signs, bilobular with thin membranes in the posterior component. There was a destruction of the opposite calvarium with exteriorisation into hypodermic soft tissue.

[A rare primitive neuroectodermal tumor: the medulloepithelioma].

Primitive neuroectodermal tumors (PNET) is a name used to describe rare and highly malignant tumors composed of undifferentiated cells resembling germinal or matrix cells of the embryonic neural tube. These tumors occur most commonly in the first decade of life, and have a particular radiological, histological and evolution features. We report a case of a PNET in an 8-year-old boy who presented intracranial hypertension studied with computed tomography scan, which demonstrated a sharply circumscribed expansive mass in the frontoparietal deep white matter, with a large cystic component, which was considered at first as a glial tumor. It was treated by total excision, and the histologic study demonstrated a medulloepithelioma. We studied the concept of PNET and their pathological, radiological and prognostic features.
