[Multivisceral tuberculosis with aortic complication in an immunocompetent patient]. / Tuberculose multiviscérale avec complication aortique chez un sujet immunocompétent.

The medical and imaging data of a 59 year old male is reported. The patient presented with cough, fever, night sweats and weight loss, for which a final diagnosis of multivisceral tuberculosis (with peritoneal involvement and mycotic aneurysm) was made, by means of CT, MRI and laparoscopic findings. This disease is uncommon in developed countries with subjects lacking the usual risk factors. Because delayed treatment may be lethal, especially with such serious vascular complication, the authors review the value and limitations of CT and MRI along with the suggestive features.

[Osteoarticular involvement in parasitic diseases: bone echinococcosis]. / Atteintes ostéo-articulaires d'origine parasitaire: l'échinococcose osseuse.

Hydatid disease is the most common human disease caused by helminths, but primary skeletal involvement is uncommon. Diagnosis is usually obtained late after considerable extension, half of which concerns the spine. The dissemination mode leads to local malignancy with severe prognosis. Medical imaging is essential. Plain x-ray findings are polymorphous and nonspecific, but computed tomography and magnetic resonance imaging are particularly useful for exhaustive pretherapeutic assessment of extension and for patient follow-up.

[Osteoarticular involvement in parasitic diseases: bone mycetoma]. / Atteintes ostéo-articulaires d'origine parasitaire: les mycétomes osseux.

Mycetoma remains a common pathology in tropical areas. Diagnosis, based on mycology and pathology is still frequently late and treatment often leaves severe functional disorders. Medical imaging is indispensable to evaluate disease spread to bone tissue. Plain radiograms usually show cortical erosion, defects with sclerosing margins, and bone thickening. CT is the most sensitive technique to detect bony involvement. CT and MR imaging, when available, are the most accurate techniques for determining disease extension in both bones and soft tissues.

[Osteoarticular involvement in parasitic diseases: bone treponematosis]. / Atteintes ostéo-articulaires d'origine parasitaire: les tréponématoses osseuses.

Bone and joint localizations of treponematosis vary greatly although there are many common features. Osteal and periosteal lesions are common. We report radiographic descriptions of bone and joint treponematosis, which must not go unrecognized due to the increasing incidence of these diseases.

[Ureteral hematoma complicating anticoagulant treatment]. / Hématomes urétéraux compliquant un traitement anticoagulant.

Submucosal hemorrhage of the ureters, are a very uncommon quoted cause of hematuria when overdosing anticoagulants. We report two cases, CT shows some very typical aspects but can also highlight, as reported formerly, another associated complication: parietal hematoma of the small bowel.

[Bladder herniation in a inguinal-scrotal hernia complicated by acute renal insufficiency]. / Extériorisation vésicale dans une hernie inguino-scrotale compliquée d'une insuffisance rénale aiguë.

We report one case of massive inguino-scrotal bladder herniation which was responsible for an acute obstructive renal insufficiency. The different types of bladder hernias and their anatomic factors are described. The clinical-radiological findings and surgical management are discussed.

[Unusual radiologic aspect of a hydatid cyst]. / Aspect radiologique inhabituel d'un kyste hydatique.

The authors report us about an unusual hydatid cyst of the liver. Ultrasound, CT and MRI exams were used, and showed an unusual fatty component inside the lesion. The development of the disease in steatosic liver is not enough to explain the unusual density.
