[Goldman Antopol syndrome associated with bilateral congenital severe factor V deficiency]. / Syndrome d'Antopol Goldman bilatéral associé à un déficit congénital sévère en facteur V.

Antopol-Goldman lesions are extremely rare. This kind of lesion is a subepithelial pelvic hematoma. This syndrome is certainly of rare occurrence and that is why a differential diagnosis of urothelial cancer in young patients who had problems with clotting must be raised. We reported a case of a 43-year-old haemophiliac with a severe congenital factor V deficit and presenting a bilateral and asynchronous Antopol Goldman syndrome. The diagnosis has been based on CT scans. The subepithelial aetiology bleeding has been shown on selective renal arteriography that allowed to cover a micro-aneurysm through the setting up of a vascular stent and a selective embolization.

[Anicteric cholestasis: imaging and diagnostic strategy]. / Une cholestase anicterique: l'apport de l'imagerie au diagnostic étiologique.

Cholestasis is due to abnormal biliary secretion, from hepatic or extra hepatic causes. The diagnostic strategy of anicteric cholestasis will be discussed, defining hepatic biologic abnormalities, and the role and sequence of imaging techniques based on clinical and biological findings. Main causes will be emphasized and illustrated with different radiological techniques (US, CT and MRI).

[Anatomic study and clinical application of the skin paddle of the serratus anterior free flap]. / Etude anatomique et applications cliniques des caractéristiques de la palette cutanée du lambeau libre de grand dentelé.

SUBJECT: Several authors used musculocutaneous free flaps of serratus anterior. However, the localization and dimensions of its skin paddle are not clearly defined in the literature. Thus, we realized an anatomical study trying to prove the reality of this skin paddle and its localisation, before considering clinical applications. PATIENT AND METHODS: Twenty-six dissections on 13 fresh anatomical subjects were realized. The protocol consisted in catheterization the thoracic branch of the thoracodorsal artery to inject a mixture of iodized product and methylene blue. The results were obtained by direct measurement of the blue cutaneous area and by radiographic evaluation of the radiopaque area, compared to reproducible anatomical reference marks. RESULTS: Twenty-five dissections were interpretable with superposable results. The skin paddle was always located compared to the 5th, 6th and 7th ribs between the anterior axillary line and the mamelonnary line. The area of the skin paddle was 11,75 cm of length (10-14), 10,75 cm of width (9-12) and 125 cm(2) from surface (110-140). Then, we realized between January and December 2003 several clinical applications of this anatomical study. We report 12 cases of free flaps of serratus anterior with skin paddle for the monitoring of the flap (4 musculocutaneous, 5 osteo-musculo-cutaneous, 3 of fascia with skin paddle). CONCLUSION: This study comes to the support from the anatomical observations from Salmon, the per-operational observations of several authors and our own clinical experiment. It certifies the autonomy of cutaneous vascularization by branches resulting from the surface fascia of the muscle. It specifies the localization and dimensions of the skin paddle of the serratus anterior flap in its muscular, osteo-muscular or fascial form, which still increases its versatility of use.

[Complications of fluoroscopy-, ultrasound-, and CT-guided percutaneous interventional procedures]. / Complications des gestes interventionnels percutanés sous contrôle radioscopique, echographique ou scanographique.

The purpose of this article is to describe potential complications following the most common image-guided (fluoroscopy, ultrasound or CT) percutaneous interventional procedures, both diagnostic and therapeutic, thoraco-abdominal and musculoskeletal, as well as to review risk factors and the best practice recommendations. Prior to any interventional procedure, it is necessary to ascertain the absence of any abnormality in coagulation, to secure enough time to explain the procedure to the patient, and to adhere to strict sterile technique. Indeed, infections and hemorrhagic complications are the principal causes of mortality and morbidity for all procedures. Following lung biopsy, CT scan detects an immediate pneumothorax in 30% of patients. Major complications following percutaneous liver biopsy occur within 3 to 6 hours. Following a percutaneous drainage, complications occur in less than 10% of cases. Following a radiofrequency thermal ablation of malignant tumors, the mortality rate is low (0,5 to 1,4%), infection and hemorrhage are the most frequent complications. While rare, septic arthritis is the main complication that can follow musculoskeletal procedures and is a cause of medical malpractice lawsuits brought by patients.

[Subfascial lipomatous tumors: management in a series of 37 consecutive cases]. / Tumeurs graisseuses sous-aponévrotiques: stratégie de prise en charge à propos d'une série continue de 37 cas.

PURPOSE OF THE STUDY: The prognosis of subfascial lipomatous soft tissue tumors depends greatly on their histological type ranging from benign lipomas that cause little local or general problems to the severe prognosis of liposarcomas that exhibit both local and distant extension. However, the clinical presentation of the two types of tumors may be similar and thus quite misleading, sometimes leading to inappropriate management and severe consequences. The main objective of this study was to determine whether the preoperative work-up in patients treated for musculoskeletal tumors within our recruitment zone is adequate, allowing appropriate therapeutic decisions. In addition, we wanted to know what explorations are most pertinent for the differential diagnosis between benign and malignant subfascial lipomatous soft tissue tumors. MATERIAL AND METHODS: Thirty-seven patients with subfascial tumors were included in this study. There were 16 with benign lipomas and 21 with liposarcomas. All the patients with benign lipomas but only 9 (43%) of those with liposarcoma had received initial care within our recruitment zone before final diagnosis. Two cases had been referred after biopsy and 1 after resection by morcellation; the 9 others were secondary referrals after tumor recurrence. Only 5 of these 12 referred patients had had an MRI exploration prior to surgery, 2 with an erroneous interpretation. An MRI series was obtained for all the patients with benign lipoma and for the 9 with liposarcomas who attended our units directly. A biopsy was also obtained in case of suspected liposarcoma. Two radiologists blinded to the final diagnosis reviewed the available MRI to assess their diagnostic value for subfascial lipomatous soft tissue tumors. RESULTS: No case of recurrence, after marginal resection (10 cases) was noted for lipomas. Six are under observation with regular MRI (with no change in size or signal). Four patients with liposarcoma died from their disease (19%) and 2 who had undergone "curative" resection had a recurrence (12%). Incorrect or imprecise (incomplete, incorrectly interpreted or no MRI) preoperative diagnosis led to additional morbidity with 3.4 surgical procedures (mean per patient) compared with 1 in patients who had had undergone a complete work-up and whose diagnosis was established after multidisciplinary discussions. Among the diagnostic elements available before pathology, only MRI findings had diagnostic value for subfascial lipomatous soft tissue tumors: for benign lipoma positive predictive value=92% and negative predictive value=93%. DISCUSSION: The clinical course of the benign lipomas and the sarcomas in this series confirm the radically different prognosis of these two tumors, both in terms of local extension and survival. Inadequate management in the initial diagnostic stages-i.e. lack of MRI with contrast injection, biopsy and multidisciplinary interpretation prior to treatment-raises the risk of higher morbidity, particularly a significantly greater number of reoperations, and progression to a higher grade of malignancy for two tumors. Our retrospective analysis enabled us to develop a decision making tree for patients with subfascial lipomatous tumors. Prospective validation will be necessary.

[MR cholangiopancreatography in choledochal cysts]. / Cholangio-pancréatographie par IRM des kystes du cholédoque.

PURPOSE: To assess the value of MR cholangiopancreatography (MRCP) in the diagnosis and preoperative evaluation of choledochal cysts. MATERIAL AND METHODS: Five patients (aged between 6 days and 28 years) were investigated by MRCP, referred for ultrasonographic detection of a bile duct dilatation or a cystic structure, of antenatal diagnosis (1 case), for jaundice or abdominal pain (3 cases) or in late follow-up of a choledochal cyst surgery. Two endoscopic-ultrasonographic studies were performed. The five patients underwent surgery without preoperative biliary cholangiography. MRCP was performed using a HASTE sequence in frontal, oblique, axial planes (1,5 Tesla MR unit). RESULTS: MRCP allowed to confirm choledochal cyst, helps to specify the anatomical type (2 type I, 3 type II), detects choledocholithiasis (3 cases). Anatomic correlation was perfect. MRCP allowed to exclude gastrointestinal duplication. Anomalous junction of the pancreaticobiliary duct was found in one case. CONCLUSION: MRCP diagnoses choledochal cysts, specifies type, helps surgery and can avoid endoscopic retrograde cholangiography or endoscopic sonographic examinations especially for children. It may find an anomalous junction of the pancreaticobiliary duct.

[Vertebral vacuum phenomena]. / Vides rachidiens.

The spinal vacuum phenomenon is a collection of gas within the disk space, the vertebral body, the apophyseal joint or the spinal canal. The intradiscal vacuum phenomenon is frequently observed in degenerative disk disease and crystal-induced diskopathy. This has obvious significance to the radiologist, who, on observing a narrowed disk space or collapsed vertebral body, might otherwise consider infectious or neoplastic spondylitis, a likely possibility. The presence of vacuum phenomenon militates against the diagnosis of infection or tumor.
