    Microcystic adenoma of the pancreas: Report on four cases and review of the literature (1991)

    Notes: Abstract Four cases of microcystic adenoma of the pancreas, including ultrasonographic (US) and computed tomographic (CT) data, are described. These tumors generally present as large, well-delimited pancreatic masses whose multicystic nature is readily evidenced on postcontrast CT scans. While the presence of cysts less than 2 cm in diameter and a central, star-like calcification are very specific, the frequency of atypical forms generally justifies exploratory surgery.

    Notes: Abstract. Two cases of agenesis of the horizontal segment of the left portal vein are reported. This very rare vascular anomaly probably corresponds to an embryological variation rather than to an obstruction of the left portal vein. In almost all cases liver ultrasonography is sufficient for identifying such vascular abnormalities. It shows a large aberrant vessel emerging from a right anterior segmental portal branch and running transversely in the quadrate lobe towards the teres ligamentum from which the portal supply to the left lobe arises. It is important to be able to recognize the magnetic resonance imaging features of this vascular variation, as magnetic resonance imaging may be the initial imaging study, and ultrasound may be technically challenging. To our knowledge, we present the first description of these features, including an enhanced gradient-echo T1-weighted sequence, a turbo spin-echo T2-weighted sequence with fat saturation, and a three-dimensional phase-contrast magnetic resonance portography.

    Primary tumour staging of gastric and colorectal cancer (1996)

    Notes: Abstract Almost 15 years after its introduction, endosonography or endoscopic ultrasonography is an important technique in a wide range of gastrointestinal diseases. Other imaging techniques are CT, MRI and barium examination. There is a general consensus that the most important prognostic factor in gastric and colorectal carcinoma is the presence or absence of lymph node invasion, but malignant fixation of tumour through direct invasion of adjacent tissues also appears to be very important. Non-invasive preoperative assessment of tumour stage based on one or a combination of the above imaging modalities should allow appropriate treatment to be planned in each case.

    Benign liver lesions: implications of detection in cancer patients (1995)

    Notes: Abstract A review of liver sonograms obtained for cancer patients (excluding primary liver cancers) over a 12 year period found 829 benign lesions: non-parasitic cysts (427 cases), hemangiomas (216 cases), solitary calcifications (79 cases), focal fatty infiltration (62 cases), and miscellaneous lesions (45 cases). These benign pathologies represented 41.8% of the focal hepatic lesions observed during this period in this population; hepatic metastases accounted for the remaining 58.2%. Marked female predilection was noted for the nonparasitic cysts, hemangiomas, and focal fatty infiltration; 63–78.7% of these lesions were solitary, and first-line imaging by US was sufficient for diagnosis of 66.1–98.2% of cases. Analysis of lesion evolution over more than 5 years revealed modifications in 17% of hemangiomas, 23.9% of nonparasitic cysts, and 75% of cases of focal fatty infiltration. Systematic pretherapy liver sonography can be proposed owing to the high frequency of benign liver lesions that can create diagnostic problems during follow-up of cancer patients.

    Benign fibrous mesothelioma of the pleura: MR study and pathologic correlation (1996)

    Notes: Abstract Benign fibrous mesothelioma of the pleura is a rare tumor of mesodermal origin. We describe the MR findings in three pathologically proven cases. All three tumors were imaged by MR as well-circumscribed lesions with smooth margins in contact with the pleura, but without chest wall invasion. Their low signal intensity on T1-and T2-weighted sequences reflect their fibrous nature. In one case a pedicle connecting the tumor to the chest wall was visualized on a sagittal MR scan. In two cases gadolinium-enhanced T1-weighted gradient echo sequences revealed intense contrast uptake by the tumor correlated with the intratumoral hypervascularization noted by histologic examination. Although the number of cases presented is small, MR seems to be the most accurate imaging modality in the assessment of the diagnosis.

    Sonographic diagnosis of solitary solid liver nodules in cancer patients (1996)

    Notes: Abstract The purpose of this study was to analyse the sonographic patterns of solitary solid liver lesions in cancer patients and to evaluate the diagnostic accuracy of ultrasound alone and in combination with other techniques (liver function tests, histology). A total of 422 solitary solid liver lesions (SSLL) were diagnosed by ultrasound in cancer patients; 197 lesions were benign and 225 malignant. The predominant aetiology for hypoechoic SSLL (128 cases) was metastasis (112 cases), whereas most hyperechoic SSLL (265 cases) were haemangiomas (155 cases) rather than a metastasis (86 cases). The 29 isoechoic SSLL included 27 metastases and 2 benign lesions. A halo was found to be highly predictive of malignancy (97%–100%). The positive predictive value for malignancy of an SSLL was very high when the results of liver function tests were abnormal (97%–100%). In our experience, histological proof is unnecessary in the majority of liver lesions in cancer patients.

    Notes: Abstract. Pseudomembranous aspergillus bronchitis is considered as an early form of invasive pulmonary aspergillosis, a well-known airway infection in immunocompromised patients. Radiologic features concerning invasive aspergillosis of the airways have been reported. However, we describe here an unusual feature of invasive aspergillus bronchitis, never reported to date, observed in a double-lung transplanted patient. Chest radiograph and CT revealed significant peribronchial thickening without any parenchymal involvement.

    Notes: Abstract. The authors describe the discovery of ascending colonic variceal veins via celiomesenteric diagnostic angiography following a bout of melena in a 44-year-old woman. Magnetic resonance imaging, including phase-contrast MR venography, allowed visualization of the portal and systemic veins immediately after the initial angiograms. The hemorrhagic episode did not resolve until after transjugular intrahepatic shunt insertion and selective variceal embolization through the shunt. At 1 week-, 3 months-, and 6 months post treatment, follow-up MR venography no longer revealed the presence of colonic varices. Colonoscopy at 6 months was normal and the patient did not have any further episodes of bleeding until a liver transplantation was performed after 9 months.
