[The treatment of acute cholecystitis by percutaneous cholecystostomy].

The authors report on their personal experience with percutaneous cholecystostomy (PC) in 36 cases of acute cholecystitis (AC). PC was successful in 34 cases, improving the clinical condition of the patients within the first hour following treatment and normalizing the laboratory data within 24-48 hours. Twenty-seven patients with calculous AC underwent cholecystectomy within 4-15 days. In 6 cases (3 calculous and 3 acalculous ACs) PC was the only treatment performed; in one case (calculous AC) PC was combined with lithotomy, the stone fragments being extracted via the cholecystostomy. According to literature reports, to date PC has been performed mainly--as an alternative to surgical cholecystostomy--on the patients unsuitable for cholecystectomy due to their age or to severe impairment of their conditions. In our experience, the procedure can be performed on a wider range of patients as a final (notably in acalculous AC) or temporary step (notably in calculous AC where it may allow cholecystectomy to be delayed and thus performed under better clinical conditions, with decreased morbidity and mortality risks).

Cystic tumors of the pancreas: evaluation by ultrasonography and computed tomography.

The personal series of 30 cystic tumors of the pancreas [12 serous cystic tumors (SCT) and 18 mucinous cystic tumors (MCT)] is presented. All neoplasms were evaluated with ultrasonography (US) 28 of 30 with computed tomography (CT); the tumoral histotype could be correctly defined in 73% of cases (seven of 12 SCT and 15 of 18 MCT). Percutaneous fine-needle aspiration (FNA) with diagnostic aims (preparation of cytological smears and/or biochemical assays) was performed in only 10 of 30 cases, yielding a 100% sensitivity; on the whole, the combined use of imaging modalities and FNA allowed correct characterization of the cystic tumors in 27 of 30 cases (90%). The usefulness of a precise diagnostic workup of these neoplasms is emphasized, due to their prognostic and therapeutic outcome.

[Magnetic resonance in the study of the temporo-mandibular joint. I. Anatomo-functional findings].

Thirty-four temporomandibular joints (TMJ) were examined in 17 normal subjects with two superconductive MR units at 1T and 1.5T. TMJ evaluation was performed with both SE sequences in occlusal position and with "fast" sequences (flash) during the gradual opening of the mouth. Therefore, both the anatomic features of the TMJs and their dynamic behavior during mouth opening were analyzed. The information acquired allowed the complete and non-invasive evaluation of TMJ function. The knowledge of the normal anatomic and functional patterns is of paramount importance for the diagnostic approach to TMJ pathologic conditions.

[Magnetic resonance imaging in study of the temporo-mandibular joint. II. Pathologic findings].

A total of 107 temporomandibular joints (TMJ) were examined with two superconductive MR units at 1T and 1.5T. In 73 TMJs, MR revealed 55 disk displacements, 7 disk perforations, 10 joint space adhesions, 33 osteoarthrities, 3 avascular necroses of the mandibular condyle, and 25 joint effusions. These abnormalities are described and discussed. In spite of some limitations--e.g., motion artifacts and patients' claustrophobia--MR imaging is the procedure of choice in abnormal TMJs, because it yields useful information as to therapeutic choice (conservative versus surgical). Arthrography can be used as a complementary study technique in the patients with marked disagreement between clinical and MR findings. Arthroscopy should be used as a surgical procedure in abnormal TMJs selected by previous MR studies.

The contribution of ultrasonography and computed tomography in the diagnosis of nonfunctioning islet cell tumors of the pancreas.

The personal series of 12 nonfunctioning islet cell tumors (NFIT) of the pancreas is reported. The ultrasound and computed tomography features of NFIT are analyzed, and a few signs are identified that may be useful in the differential diagnosis vs ductal carcinoma. The necessity to complete the diagnostic work up by means of fine needle aspiration biopsy and cytologic smears is also emphasized.

[Diagnostic imaging of pancreatic metastasis].

The authors present their personal series of pancreatic metastases (8 cases) which were evaluated with different imaging modalities--i.e., sonography, computed tomography, and angiography. Possibilities and limitations of non-invasive modalities are pointed out, and the usefulness of angiography is emphasized for the identification of small hypervascular lesions. The fairly rare diagnosis of these tumoral lesions is due to 3 causes: low incidence of pancreatic metastases; their frequently small size which justifies eventual false negatives; the frequent lack of symptoms calling for imaging modalities. Moreover, pancreatic metastases are usually diagnosed in an advanced stage. Thus, the therapeutic approach must be planned in every single case, in relation to the perspectives of survival and to the residual quality of life.

[Odontogenic sinusitis. An evaluation and the radiologic checkup protocol after a Caldwell-Luc intervention].

A homogeneous group of 30 patients who were operated over a 5-year period for odontogenic sinusitis using a buccosinusal communication following Caldwell-Luc's technique were studied. A marked discrepancy between the conventional X-ray picture and the clinical picture emerged from these 30 case studies. So as to find an explanation for this discrepancy, all patients underwent CAT tests. On the basis of a critical evaluation of the results obtained it is suggested that patients be followed using a postoperative instrumental control protocol.

[Portal circulation following the Warren operation--computerized tomography study of portal hemodynamics 5 to 11 years following distal splenorenal anastomosis].

18 patients underwent CT-investigation with bolus injection of contrast medium 5 to 11 years after splenorenal Warren shunt. According to this investigation all patients were found to have developed hepatofugal collaterals in consequence of distal splenorenal anastomotic suction. In most cases the portal liver perfusion was maintained. These effects are not homogeneous and show variations from patient to patient.

[Portal circulation following Warren's operation. Long-term control using computerized tomography].

Computed tomography with contrast injection was carried out in 18 patients who had undergone a Warren procedure for portal hypertension due to cirrhosis of the liver more than five years previously. The results show that it is not possible to drain only a part of the venous portal territory. The portal circulation does not consist of two portions, with different pressure relationships. Pressure difference across the splenorenal anastomosis is greater than that into the mediastinal veins. Postoperative development of a hepatofugal circulation continues for a long period and is not confined to the early phase only. This phenomenon is, however, not uniform. In particular, there are variations in the extent of the collateral circulation and in the maintenance of liver blood flow.

[Radiologic approach to endocrine pathology in childhood].

The new imaging techniques (ultrasound, CT, digital subtraction angiography) have greatly modified the diagnostic approach to the endocrinopathies in pediatric age, notably if of surgical interest. The main clinical indications to the ultrasound and/or CT study of hypophysis, thyroid, adrenals and female internal genital tract are synthesized in this paper. A diagnostic flow-chart is also suggested for each clinical entity.

Choice between US and CT in the radiological approach to the renal masses.

The diagnostic reliability of ultrasound (US) and computed tomography (CT) has been analyzed in 114 patients with renal masses (RM) detected by urography and consequently submitted to both exams. A flowchart is suggested in order to avoid useless examinations; accordingly, the US examination is always justified in the study of RM as opposed to the CT examination (requested only in 50% of RM) and angiography (requested only in 35% of RM).

[Transhepatic embolization of oesophageal varices (author's transl)].

Personal experience (12 cases) and a literature review (165 cases) of trans-hepatic embolization of oesophageal varices are evaluated; indications, contra-indications, complications and results are discussed. Results are analyzed in term of: history of past bleeding, bleeding at the moment of the procedure, successive surgical or medical treatment. Moreover portal haemodynamics variations induced by the procedure are evaluated.
