[Acute cholecystitis using computed tomography: usefulness of the trabeculation of the peri-cholecystic adipose tissue].

PURPOSE: To evaluate the significance of pericholecystic fat stranding on CT, and to compare it to other CT findings in patients with acute cholecystitis. MATERIALS AND METHODS: The CT examinations of 14 patients with proven acute cholecystitis were retrospectively reviewed and evaluated for the presence of findings consistent with this diagnosis. RESULTS: The most common CT finding was stranding of the pericholecystic fat (13 patients), followed by gallbladder distension (11 patients). Pericholecystic or perihepatic fluid was present in 6 patients in association with severe acute cholecystitis (6 patients) and biliary peritonitis (2 patients). CONCLUSION: Stranding of the pericholecystic fat was the most common CT findings in patients with acute cholecystitis, followed by gallbladder distension.

[Arteriovenous fistula following femoral angioplasty].

We describe a case of arteriovenous fistula developing at the site of balloon dilatation immediately after percutaneous transluminal angioplasty of the superficial femoral artery. This occurred during an otherwise uncomplicated angioplasty. The fistula was treated by inflating a slightly larger balloon with a good clinical result as confirmed by color Doppler ultrasound. This uncommon complication of angioplasty is not widely recognized.

Therapeutic approach to arteriovenous malformations of the tongue.

Arteriovenous malformations (AVM) are developmental errors with a high complication rate because they are hemodynamically active. The aim of our study is to evaluate management of the rare subgroup of tongue AVM. From 1982 to 1994, 25 patients with AVM of the tongue presented to our department. All patients were discussed in our multidisciplinary staff consultation and were treated by embolization, surgery, or were followed-up clinically with no intervention. Thirteen patients were asymptomatic in a hemodynamically quiescent phase and did not require any kind of intervention. The 12 others underwent embolization procedures following which 6 became stable, 2 had complementary surgery, 1 was lost to follow-up, 1 had two minor bleeding episodes without the need for hospitalization, and 2 were improved. Arteriovenous malformations of the tongue must be followed clinically and treated only if they become active. Permanent embolization with a polymerizing liquid administered through supra-selective catheterization or by direct puncture of the malformation is recommended.

[Value of sonography in prolonged neonatal jaundice. Findings in 13 cases].

BACKGROUND: Different conditions are associated with a prolonged cholestatic jaundice in the neonatal period: viral hepatitis, biliary atresia and choledocal cyst are the most frequent causes. Laboratory findings are necessary, although they do not permit an etiologic diagnosis in all cases. Serial ultrasonographic study could be proposed for the evaluation of biliary excretion before and after feeding, in order to differentiate between these three conditions. PATIENTS AND METHODS: Between February 1993 and January 1997, 13 newborns (seven girls and six boys) aged from 30 to 186 days, presented with jaundice and conjugated hyperbilirubinemia. They were evaluated by laboratory tests; serial ultrasonographic examinations were performed after 4 hours fasting then 1 and 2 hours after meal. RESULTS: The gallbladder (GB) was visualized in nine patients. In five of these patients, it contracted after feeding suggesting the diagnosis of neonatal hepatitis, that was confirmed by the clinical evolution. In three patients, the GB did not change in size and the diagnosis of biliary atresia was surgically proven. In one patient, a choledocal cyst was visualized and confirmed by surgery. The GB was not identified after 4 hours of fasting in four patients; biliary atresia was suspected and confirmed by surgery. CONCLUSION: Serial ultrasound of the GB is an easy and non-invasive method. It was useful in identifying those conditions requiring surgery in eight patients. We recommend its use as the initial method in the evaluation of neonatal jaundice before the other invasive methods.

[Cavernous dural fistulas: Importance of trans-ocular Doppler ultrasound in evaluating venous patency and therapeutic choices].

Transcranial Duplex scan is a relatively recent diagnostic tool with many unexplored clinical potentials. The authors insist on the role of transocular exploration, as a non-invasive substitute to angiography and discuss two patients with cavernous meningeal arteriovenous fistula, a benign but relatively uncommon disease. In the first patient, in whom symptoms recurred, Duplex scan was able to rule out thrombophlebitis and to show increased flow in the fistula, thus leading to proper treatment. In the second patient, the identification of a periorbital thrombophlebitis innocented the fistula and prompted anti-coagulation. We conclude that besides its diagnostic capabilities, Duplex scan may be helpful in selecting proper treatment and follow-up in specific neurovascular conditions.

Isolated brain metastases of osteosarcoma in a patient presenting with a patent foramen ovale.

We report the case of a patient in whom brain MR imaging was requested for initial symptoms of intracranial hypertension. The presence of multiple intracranial hemorrhagic lesions suggested brain metastases. Body screening showed periosteal osteosarcoma of the left fibula with no lung metastases, but with a patent foramen ovale which probably allowed neoplastic cells to reach the brain without being filtered through the lungs. The conclusion of this study was that a left-right cardiac communication is to be considered in cases of isolated brain metastases from osteosarcoma.

[Imaging aspect of a case of fibrodysplasia ossificans progressiva].

Fibrodysplasia ossificans progressiva is a rare congenital disease that affects children under the age of five years. Soft tissue swelling of the cervical and dorsal regions with local pain, warmth and low grade fever are the early clinical manifestations, usually associated with hallux valgus and microdactily of the fingers and toes. Calcifications of the fascias and muscles cause muscular contractures leading to progressive disability and restrictive lung disease. In the early stage, CT shows edema of the soft tissues and later on, calcifications of muscular fascia. The association of these radiographic and CT findings is specific and should avoid muscular biopsies which are known to be an aggravating factor in this disease.

[A rare cause of diplopia: a sinus cavernous dural fistula. A case report].

Dural fistulas of the cavernous sinus represent a relatively unknown etiology for diplopia. The authors report on a case where combination of MR and transcranial Doppler (especially transocular) helped in diagnostic and therapeutic approach. They propose a new algorithm for the management of diplopia.

["Mirror" intracavernous aneurysms. Therapeutic dilemma apropos of a case with review of the literature].

"Mirror" cavernous aneurysms are exceptional; only 66 such cases having been published until mid-1996. We report on a 68-year-old woman who presented for left exophthalmos, diplopia and neuralgia. MR and angiography demonstrated a giant symptomatic aneurysm on the left side and an incidental small one on the right side. The patient was treated in two sessions: first, she had selective embolization of her right aneurysm; two weeks later, her left carotid artery was sacrificed with detachable balloons, after a well-tolerated occlusion test. This original and successful approach permitted to achieve a reasonable goal when considering the patient's age, operative morbidity, risk of future complications and final result. A review of the pathophysiology, clinical manifestations and therapeutic indications is presented and discussed.

[Percutaneous bile drainage in neoplastic obstructive pathology of the biliary tract. Experience of the Hotel-Dieu of France in 100 drainages].

Between 1981 and 1994, a 100 biliary drainages were introduced transhepatically in 71 patients with malignant biliary disease. Eighty-six endoprosthesis were inserted, 6 internal-external drainages and 8 external drainages. Our success rate in catheterization of the stenosis was 97%. The early complication rate was 17% (12/71) most often due to hemorrhage (n = 3), infection (n = 4), duodenal perforation (n = 1), biliary leak (n = 2) and death by septic shock (n = 2). Twenty-nine patients with 39 endoprosthesis had a long-term follow-up. The most common late complication observed was occlusion (15/39, 37%) and migration (1/39, 2.5%). Specific treatment of complications was carried out in 10 of the 29 patients (35%). It is concluded that patients with inoperable malignant obstruction of the bile ducts should be offered an indwelling endoprosthesis whatever their prognosis; an occluded stent can be removed or at least bypassed in nearly all patients, thereby maintaining palliation of symptoms.

[Percutaneous renal angioplasty. Experience of the Radiodiagnostic Service of the Hotel-Dieu of France].

OBJECTIVE: We report on a series of 42 renal artery stenosis treated with percutaneous transluminal angioplasty (PTA). MATERIALS AND METHODS: From January 1988 to June 1996, these 42 renal artery stenoses were found in 33 patients (17 males and 16 females) who had a balloon dilation (with 3 stent deployment); 9 of these lesions were bilateral and 7 on a single kidney. Initially, 32 patients had a high blood pressure and 6 a progressive renal failure. Twenty-two patients presented an atheromatous pathology, 7 a fibromuscular dysplasia. One patient had a Takayasu arteritis, and 3 others a stenosis of the renal graft artery. RESULTS: We find a complete initial success in 86% of the patients, a partial success in 14% without any catheterization failure. Global success rate of PTA is 90% at 29 months mean follow-up. A benefit of PTA regarding blood pressure was found in 84.4% of the patients. The renal function became normal in half the patients with renal insufficiency. CONCLUSION: PTA is an efficient treatment for renal artery stenosis. A satisfactory improvement of blood pressure and renal function is found in a high number of patients.

[Complications of percutaneous nephrostomy. Apropos of 481 procedures: the value of puncture of the median calices].

The authors report on a series of 481 percutaneous nephrostomy procedures, and describe the complications encountered. 163 percutaneous nephrostomies for drainage and 318 percutaneous stone removals, were performed between 1985 and 1995 in the Radiology Department of Hôtel-Dieu de France Hospital under fluoroscopy. One tract was needed for PN but more than one was sometimes necessary for percutaneous stone removal. Complication rate was identical to the results reported in the literature. Complications were more frequently encountered when the upper calyx was punctured (intercostal approach), mostly pleural lesions. Puncture of the middle and inferior calyx were associated with the same rate of complications, but with different degrees of severity. Major complications (80% of cases of hemorrhage, including all arteriovenous fistulae and pseudoaneurysms) were encountered with the puncture of the lower calyx while those associated with the puncture of the middle calyx were minimal. Thus, puncture of the middle calyx is the least morbid. It is recommended by the authors, whenever possible.
