[Susceptibility weighted imaging. Theory and applications].

Susceptibility Weighted Imaging (SWI) is a new MR imaging technique using the BOLD effect (Blood Oxygen Level Dependent) and the differences of susceptibility between tissues. It is a 3D gradient echo, fully velocity compensated sequence. The echo time is chosen to maximize the signal cancellation in veins and a specific post-processing is applied using the phase images as a complementary source of contrast. It is very useful for the visualization of veins either normal or abnormal. It shows hemorrhage, even of small quantity, better than conventional gradient echo sequences. Its use is still limited by a long acquisition time and some remaining artifacts.

[Current problems in geriatrics and radiology. Teleradiology: organization and evaluation].

The realization of radiological examinations in the elderly population must be adjusted to the needs of patients that usually have health problems and very little patience. Its organization must be thought as a whole: appointment, reception of an awaited patient, human accompaniment allowing good cooperation, nursing support, and prompt availability of reports. Adapted equipment facilitates the examination: stretchers to raise and carry invalid patients, digital radiography. Structural linking of radiology and geriatric units with a departmental support avoids the isolation of medical and ancillary staff, reinforce the bonds with geriatricians and facilitates the access to CT before any contrast-enhanced (barium, iodinated) examination. Teleradiology is a complementary tool of making the medical support available and reinforce the interactivity with geriatricians. The simplicity of the questions in current geriatrics makes it possible to use teleradiology in daily practice.

[Pseudotumoral enterocolic phlebitis of the cecum and rutoside. A case report].

INTRODUCTION: Enterocolic phlebitis is an entity characterized by ischemic injury of the gastrointestinal tract caused by thrombophlebitis of the mesenteric veins without arterial involvement or systemic disease. EXEGESIS: We report a case of enterocolic phlebitis in a 57-year-old female treated by rutoside, revealed by intestinal obstruction related to a pseudotumoral lesion of the caecum. CONCLUSION: This case adds to the four cases of enterocolic phlebitis under rutoside already reported in the literature, suggesting a possible involvement of this drug in this rare disease.

[Ovarian vein thrombophlebitis and post-partum fever].

INTRODUCTION: Ovarian vein thrombophlebitis (OVT) is a rare but potentially threatening complication of the postpartum period. Diagnosing it may be of some difficulty especially in case of symptoms mimicking appendicitis or pyelonephritis. EXEGESIS: We report 2 patients with postpartum right OVT. The clinical presentation included high grade fever, and pain, lumbar in one case, of the right flank in the other. Pulmonary embolism complicated both cases. CONCLUSION: Diagnostic and therapeutic management of OVT was transformed by progresses in medical imaging during the 1980's. However, optimal duration of anticoagulant treatment and secondary prevention indications have to be determined.

Latent autoimmune thyroiditis in untreated patients with HCV chronic hepatitis: a case-control study.

In order to establish a relationship between Hepatitis C virus (HCV) chronic infection and autoimmune thyroiditis, 97 untreated patients with biopsy-proven HCV chronic hepatitis and 97 controls were studied. An ultrasound examination of the thyroid and an assay of serum thyroid-stimulating hormone (TSH), thyroid hormones and anti-thyroid antibodies were performed in all cases. The overall prevalence of thyroid abnormalities was higher in patients than in controls (17 vs. 4%, P<0.01) and the prevalence of anti-thyroid antibodies was significantly different between the two groups (P<0. 02). HCV patients with (n=13) compared to HCV patients without anti-thyroid antibodies (n=84) were older, predominantly female, and more frequently had increased serum TSH levels or a hypoechogenic pattern of the thyroid gland, while Knodell's score and prevalence of cirrhosis were similar. Latent autoimmune thyroiditis is more frequent in untreated HCV patients than in controls. This finding raises questions about the mechanism of autoimmunity induced by HCV and provides an explanation for the high rate of overt autoimmune thyroiditis during interferon treatment in these patients.

A case of malrotation and situs ambiguus.

Isolated levocardia is a rare condition in which intestinal malrotation may be encountered. The case herein reported is particularly uncommon and raises a number of questions about the development of abdominal symmetry.

[Cranial pachymeningitis].

INTRODUCTION: Pachymeningitis is a fibrous inflammatory process with non-specific symptoms, involving the dura mater. Due to MRI development, diagnosis is both easier and earlier. CURRENT KNOWLEDGE AND KEY POINTS: We report seven cases and review current literature. Clinical features are headaches and cranial nerve palsies. CSF shows inflammatory changes, while MRI evidences thickening of the dura mater. Disease etiologies in the present study were tuberculosis in two cases, sarcoidosis, Lyme disease, lymphoma and dural puncture; in one case only the disease was of unknown origin. The condition of six patients improved with specific treatment. FUTURE PROSPECTS AND PROJECTS: Further MRI development should allow detection of new forms of pachymeningitis and standardization of patients' management through the study of more important series.

Aortitis with antiphospholipid antibodies: CT and MR findings.

Two cases of aortitis associated with the presence of antiphospholipid antibodies (APAs) are reported. Only CT and MR imaging were able to show these unusual form of aortitis preferentially affecting the outer aortic tunics. We conclude that aortitis could be a new manifestation of primary antiphospholipid syndrome (APS) and the initial pathological process before the development of aortic thrombosis, reported as a classical complication of APS.
