[MRI in the differential diagnosis of liver focal lesions].

51 patients with focal liver abnormalities at ultrasound were examined by MRI. The cases with liver metastasis of known origin submitted for staging and cholangiocarcinomas of the external bile ducts or gall bladder with liver invasion were not included in the study. Most of the examinations were performed for suspected hepatocarcinoma.

[MRI in acute pancreatitis].

26 patients with clinical and biological suspicion of acute pancreatitis were examined by MRI. The general indications for pancreatic MRI were: suboptimal or equivocal CT or ultrasonography findings (e.g.

[Plunging ranula].

The plunging ranula is a relatively uncommon phenomenon which represents a mucus escape reaction occurring from disruption of the sublingual salivary gland. We present a retrospective study over a 10 years period on patients suffering of plunging ranula treated in Oral and Maxillo-Facial Clinic, resumed by a clinical example. These 7 patients with plunging ranula are related to all the patients operated for ranula in the same period of time in our clinic and were analyzed on age, sex, imaging exploration technique, treatment, and outcome.

[Transitional cell carcinoma of the upper urinary tract- staging by computed tomography].

Purpose: To determine the accuracy of computed tomography (CT) in staging transitional cell carcinoma of the renal pelvis and calyces and to identify whether hydronephrosis proximal to the tumor used as a criterion for minimal invasion may improve the overall accuracy of the method.

Materials And Methods: 24 patients with transitional cell carcinoma of the upper urinary tract underwent preoperative CT. In all cases nephroureterectomy was performed and CT and pathologic staging were compared.

[Role of computerized tomography in the diagnosis of transitional cell carcinoma of the upper urinary tract].

Purpose: To evaluate the computed tomography (CT) semiological criteria used in the diagnosis of transitional cell carcinoma of the upper urinary tract.

Materials And Methods: 26 patients with transitional cell carcinoma of the upper urinary tract underwent preoperative CT. In all cases nephroureterectomy was performed and CT and histopathologic findings were compared.

[Small size cephalo-pancreatic cancer. Demonstration of MRI/MRCP usefulness].

48 years old woman with obstructive jaundice has been examined by abdominal ultrasound followed by MRI. The suspicion of cephalic pancreatic cancer raised by ultrasound was confirmed by MRI and MRCP. Association of MRCP with axial and coronal T1 and T2 sequences successfully demonstrated a resectable tumor, confirmed at surgery.

[Renal cell carcinoma- diagnosis by computed tomography].

In approximately 10% of cases, renal cell carcinoma (RCC) could present as a fluid- filled cystic mass. There are three mechanisms by which RCC may become cystic: extensive cystic necrosis, intrinsic cystic growth and origin from the epithelium lining a simple renal cyst. Simple renal cysts are very common.

[Case of cystic metastasis of the liver].

The report is about a patient clinic of Iassy from oncologic clinic. He had pain in the right, back and inferior hypocondrium, with irradiation, vomitings, pain less (7 kg in 2 months), weekness. The echography shows three years ago, hepatic cysts (the patient refused the admitted in hospital).

Abdominal pregnancy. Case report, review of the literature.

Abdominal pregnancy (AP) is a rare form of ectopic pregnancy (EP). It is a medical emergency because of high maternal and fetal morbidity and mortality. Early diagnosis is essential.

[Klatskin's tumor].

During the period 1989-1998, 27 patients with primary proximal bile duct cancer were treated (17 females and 10 males with a mean age of 61 years). The main presenting symptoms were: jaundice (96.2%), itching (92.

[The Wermer syndrome].

The difficult diagnostic and therapeutic management of patients having gastrinoma with multiple endocrine neoplasia type I (MEN I) has been discussed by reference to the literature and a personal experience of 2 patients with Wermer syndrome. The syndrome is often familial and might be inherited as an autosomal dominant trait with a high but variable degree of penetrance. Pancreatic islets, parathyroid glands and adenohypophyseal [correction of antehypophyseal] cells are the three localization main for endocrine involvement in MEN I syndrome.

[Choledochal cyst in adults and cancer of the biliary tract].

We presented 3 cases of cystic dilatation of common bile duct classified as type IC, IVB an IVA. All 3 were women, admitted for right upper quadrant pain and jaundice. Two cases proved malignant degeneration in cystic dilatation in first cas and in gallbladder in third.

[Hepatic abscesses].

The authors analyse 16 cases of hepatic abscesses recorded in a 10-year interval. The difficulties in assessing the etiology and diagnosis, as well as in indicating an effective treatment are discussed. The clinical aspects and investigation methods, among which scintigraphy, arteriography and especially echotomography are extremely useful in making the diagnosis and in localizing the collection, are reviewed.

Continuous electrocardiographic monitoring during balloon dilatation in achalasia.

Electrocardiographic (ECG) changes in nine patients under continuous ECG monitoring before, during and after balloon dilatation for achalasia were followed; of these, three had ischaemic heart disease (IHD). One or several abnormalities including sinus tachycardia, supraventricular or ventricular ectopic beats, S-T segment depression and T-wave flattening appeared during the procedure; these were more commonly found in patients with IHD. Despite the high incidence of recorded ECG abnormalities, these were transient, and no treatment was needed.

[Splenic artery embolization in hematologic diseases in children].

In the past four years or so splenectomy used in children with hematological defects, who showed hypersplenism has been replaced with partial arterial splenic embolization (Pase), in general, 2/3 of the lower spleen were embolized. Pase was performed after the selective catheterization of the splenic artery up to the hilum with local anesthesia. As an embolizing agent, with the first 2 patients a suspension of Gelaspon microparticles and absolute alcohol (90 degrees) was used, and with the others (7 patients with 9 embolizations) only absolute alcohol.
