Les mycétomes sont des affections granulomateuses fongiques chroniques, d’origine exogène, s’étendant progressivement du point d’entrée cutané aux tissus profonds, avec un tropisme particulier pour le tissu osseux. Les mycétomes se traduisent par une pseudotumeur inflammatoire constituée d’abcès profonds, qui communiquent entre eux et avec des ulcérations cutanées par des trajets fistuleux. L’élément diagnostique caractéristique est la présence, au sein des foyers de suppuration et faisant issue par les fistules cutanées, de grains filamenteux qui peuvent être, soit des champignons vrais (maduromycétome ou eumycétome), soit des actinomycètes aérobies (actinomycétomes) (1). Les mycétomes se comportent comme des tumeurs à malignité locale, infiltrantes, récidivantes. Le traitement médical des mycétomes fongiques est décevant et la cure d’un mycétome reste donc avant tout chirurgicale. Son extension, osseuse plus particulièrement, est le facteur prédominant dans le choix thérapeutique, rendant souvent l’amputation inévitable. La reconnaissance de cette extension osseuse est donc capitale pour une prise en charge thérapeutique optimale de la maladie.

Nous rapportons l'observation d'un homme de 61 ans qui a presente une exteriorisation vesicale complete dans le scrotum, compliquee d'insuffisance renale aigue. Les differents aspects de hernie vesicale, le diagnostic clinique et radiologique ainsi que le traitement chirurgical sont discutes.

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.

Les auteurs rapportent le cas d’un homme de 59 ans, présentant un tableau clinique respiratoire initial associant toux irritative, fièvre, complété secondairement d’un syndrome abdominal douloureux dans un contexte d’atteinte marquée de l’état général et pour lequel le diagnostic final de tuberculose extra-pulmonaire (avec localisations cérébrales, péritonéale et aortique) a été porté sur les résultats du scanner, de l’IRM et de la laparoscopie. Si l’incidence de la tuberculose augmente dans les pays industrialisés, la forme extra-pulmonaire reste rare chez les sujets dénués de tout facteur de risque, son diagnostic ne devant pas être retardé, au risque de compromettre le pronostic, parfois même vital devant certaines localisations. Les auteurs présentent les résultats du scanner et de l’IRM, leur intérêt dans le bilan lésionnel et leurs limites quant au diagnostic étiologique.

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.

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.

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.

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.

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.

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.
