ABSTRACT: We report the 32nd case of congenital absence of portal vein in an 18-year-old female adult associated with multiple focal nodular hyperplasia of the liver. The association of various hepatic tumors has been observed in half of the publications about congenital absence of portal vein. Hepatic tumors seem to result from systemic diversion of portal vein flow with a resultant increase of arterial flow causing important vascular and nutritif changes the liver and consequent parenchymal transformation.

ABSTRACT: The purpose was to evaluate the influence of radiologist's experience on the diagnostic yield and complications of a percutaneous liver biopsy (PLB) method. Six hundred patients underwent an ultrasound-guided PLB by an inexperienced operator in 25.2% of cases (experience of less than 15 percutaneous liver biopsies performed alone--group I) or by an experienced operator (experience of more than 150 percutaneous liver biopsies--group II). The two groups were well-matched with respect to sex, age, percentage with viral hepatitis without histological cirrhosis, number of needle passes, history of liver biopsy and pain before the biopsy. A histological diagnosis was available in 97.3% of cases without any significant difference between the two groups ( P=0.25). However, group II samples were significantly longer and contained more portal tracts ( P=0.01). Pain was mild immediately and 6 h after the biopsy, without significant difference between both groups. Eight vasovagal reactions (five in group II) and one arteriobiliary fistula (in group II) occurred. With the method of PLB used for this study, operator's experience did not influence either the final histological diagnosis or the degree of pain suffered.

ABSTRACT: Acute colonic pseudo-obstruction, the so-called Ogilvie's syndrome, results in massive colonic dilation without mechanical obstruction. In most cases, a conservative treatment with or without endoscopic decompression is sufficient. In rare cases of relapses or failures, a cecostomy has to be performed. A surgical cecostomy is associated with high morbidity and mortality. However, a percutaneous cecostomy could be an interesting alternative treatment. We report the case of a 67-yr-old male with colonic pseudoobstruction for which both the conservative and the endoscopic treatments were unsuccessful. A percutaneous cecostomy was performed, and for the first time in this indication, a transperitoneal access was used with the help of nylon T-fasteners.

ABSTRACT: Purpose: To evaluate renal function before and after suprarenal inferior vena cava (IVC) filter placement.
Methods: We describe, in a personal series of 13 consecutive cases (all of them stage IV cancer patients, one LGM filter, one Antheor
filter, 11 Greenfield filters) in our institution, two cases of fatal renal vein thrombosis after placement of a suprarenal
filter. Evaluation of renal function was based on serum urea (in mmol/L; normal 3.30–6.60), serum creatinine (in μmol/L; normal
<115.1), and calculation of serum creatinine clearance. Results and conclusion: This study suggests that in advanced-stage cancer patients who have a single functional kidney, renal functional insufficiency,
or previous renal vein thrombosis, IVC filter placement above the renal veins may not be appropriate. Suprarenal filter placement
should be performed only after analysis of predicted survival, after detailed discussions with the patient, and most importantly
after renal function evaluation.

ABSTRACT: We report on the case of a patient admitted for epigastric pain. An abdominal ultrasound revealed a voluminous cystic lesion of the left hepatic lobe. In magnetic resonance imaging, the mass had a liquid-liquid level that was spontaneously hyperintense on T(1)-weighted images and hypointense on T(2)-weighted images. Magnetic resonance cholangiography identified bilateral intrahepatic bile duct dilatation. A left hepatectomy finally revealed a mucinous cystadenoma with pseudo-ovarian stroma that had a pedunculated intraductal extension to the biliary convergence.

ABSTRACT: We report a series of six benign peripheral neurogenic tumors (five schwannomas and one neurofibroma) studied by 3D ultrasonography (US) and magnetic resonance imaging (MRI). The findings demonstrated by US and MRI are variable, but usually permit the diagnosis of benign nervous tumor without prejudging the final histological diagnosis. MRI does not bring forward further complementary images to those observed at US, which is limited by its dependence on its operator. The use of 3D US will be sufficient for the diagnosis and preoperative evaluation of a lesion when it is possible to furnish the volumetric data and the tools necessary for data analysis in a single document (in a CD).

ABSTRACT: The aim of this retrospective and monocentric study was to describe the magnetic resonance cholangiography (MRC) features of biliary abnormalities related to extrahepatic obstruction of the portal vein (EHOPV).
From September 2001 to May 2003, MRC was performed in 10 consecutive patients who had a portal thrombosis.
Biliary ductal pathology was demonstrated via MRC in nine patients. It consisted of stenoses, ductal narrowing or irregularities involving the common bile duct for three patients with extrahepatic portal vein thrombosis discovered a mean of 1.5 years ago, or involving both right and left intrahepatic bile ducts and common bile duct for six patients with extrahepatic portal vein thrombosis discovered a mean of 16.2 years ago. Dilation of intrahepatic bile ducts was seen for seven patients, four of them having cholestasis. For three patients with symptomatic cholestasis, direct cholangiography (DC) was performed and showed the same findings as MRC which nevertheless overestimated the degree of bile duct stenosis.
MRC seems to constitute an accurate tool to investigate noninvasively patients with portal biliopathy.

ABSTRACT: We report six cases of lipomas of the right colon, of which one was affected by two lesions. Two cases presented with episodes of partial occlusion; the others did not present with particular symptoms. The diagnoses were based on imaging by computed tomography, which demonstrated an intraluminal formation of fatty density, not associated with tissual components or hypervascularization.

ABSTRACT: Colocolic intussusception in the adult, caused by a tumoral process, is a rare clinical event. We have studied two adults clinically presenting with a mass in the right iliac fossa, which was produced in one case by a carcinoma involving the right colon and in the other case involving the sigmoid. Multi-slice spiral CT imaging showed the presence of a colocolic intussusception-the tumoral characteristics of the lesion eliminated the possibility of a lipoma-and it allowed a satisfactory presurgical evaluation of the pathological process.

ABSTRACT: The lipomatous tumors of the adrenals are hormonally inactive lesions, often of a benign nature, such as myelolipomas, lipomas, angiomyolipomas, or mature teratomas, and are rarely malignant, such as liposarcomas. The importance of recognizing their characteristic radiological images, which would lead to their correct treatment, is fundamental since there has been an increase in the demonstration of this lesion, often detected incidentally. The various imaging procedures, although not allowing to formulate a histological diagnosis, nonetheless permit to determine the volume of the tumoral mass and their evolution. These two factors are of significant importance in the planning of the correct surgical procedure, while a third important factor is the proper evaluation of the symptoms presented by the patient. Regarding the treatment, on the basis of our own experience, which agrees with that of other authors, the surgical removal of any lesion greater than 5 cm is mandatory.

ABSTRACT: We report three cases of women who came to our observation suffering from a feeling of heaviness in the pelvic floor. Ultrasonography showed, in all cases, a cystic formation, medially located under the umbilicus, suggesting the presence of a cyst of the urachus. Computed tomography and magnetic resonance imaging, however, thanks to a more definite topographic evaluation, allowed elimination of this diagnosis in two patients with history of previous abdominal surgery.

ABSTRACT: We report a case of a patient admitted to our hospital for acute pelvic pain. Ultrasounds and abdominal CT scan found a voluminous mass situated in the upper urinary bladder and contiguous to the uterus and to the ovaries. Magnetic resonance imaging identified a pedicle connecting the uterus to the mass which had an aspect of a necrobiotic leiomyoma. Laparoscopic surgery confirmed the diagnosis of acute torsion of a subserous uterine leiomyoma.

ABSTRACT: We evaluated and compared the radiological images of the spine of 111 patients affected by myeloma, bone metastases, and fractures secondary to osteoporosis demonstrated in low-dose computed tomographic (CT) scans and those demonstrated in conventional radiographic studies. From the analysis of the data obtained, it appears that the duration of the CT procedure is definitely shorter and that its diagnostic sensitivity is superior to that of conventional radiography. We should mention that the dose of radiation delivered by CT scanning does not constitute an unfavorable element in patients, usually elderly, for whom CT scanning was indicated.

ABSTRACT: A series of 50 patients presenting with lumbar discogenic disease, and treated by percutaneous discectomy using the Dekompressor system (Stryker, Kalamazoo, MI, USA), were followed for more than 6 months, by analyzing the evolution of the painful symptomatology with the visual analog scale (VAS) system. All patients had been under treatment with analgesic or anti-inflammatory agents. The intensity of the pain was measured 2, 7, 30, and 180 days after the percutaneous discectomy. An improvement in the painful symptomatology of less than 30%, observed in 11 cases and in 1 case of epidural pathology, was considered an unsuccessful result. A decrease of the pain of more than 70% was observed in 72% of cases, either with the end of the symptoms of pain as noted in 79.5% of patients or with a marked reduction of the medical treatments obtained in 21.5%. The results obtained were already almost definitive at the seventh day of follow-up, and further controls rarely demonstrated an improvement in the pain. The location of the herniated disc is a parameter which appears to be very important in the efficacy of percutaneous discectomy. We noted an improvement of more than 70% in 79% of the posterolateral foraminal or extraforaminal hernias, although these favorable results were observed only in 50% of the posteromedian hernias.
