[Pleural colonization of thymoma]. / Le colonizzazioni pleuriche del timoma.

Six observations of peculiar pleural implants completely separated from invasive thymomas (examined by conventional chest x-ray and CT) were reviewed. CT was more effective than chest x-ray; number, size and extent of pleural lesions were underestimated by plain film studies. Moreover CT provides a densitometric evaluation of the pleural pathology being useful in differential diagnosis. CT can also be helpful as a guide to needle biopsy.

Cavernous transformation of the portal vein: sonographic and computed-tomography findings.

A case of cavernous transformation of the portal vein detected by sonography and computed tomography is presented.

[Mauclaire's disease: isolated juvenile osteochondrosis of ossification nuclei from the metacarpal head. Contribution of a case and review of the literature]. / Malattia di Mauclaire: osteocondrosi giovanile isolata dei nuclei di ossificazione delle teste metacarpali. Contributo casistico e revisione della letteratura.

A very rare case of isolated juvenile osteochondroses of epiphyseal metacarpal head nuclei is reported (Mauclaire's disease).

Thoracic extramedullary hematopoiesis: evaluation by conventional radiology and computed tomography.

4 cases of extramedullary hematopoiesis (EH) in the posterior mediastinum in patients affected with serious chronic anemia are presented. The contribution of conventional radiology and computed tomography (CT) to the assessment of an exact diagnosis, is discussed. The CT images are above all characterized by the presence of typical bilateral, asymmetrical paravertebral hyperdense masses (about 45 HU). Besides, a striated aspect of the vertebral bodies is common. For a rather sure diagnosis of EH in patients with chronic anemia, a conventional chest X-ray and CT of the thorax is sufficient. Biopsy and thoracotomy should be avoided.

[Computerized tomography of lymphomas: a simple method in the control of abdominal localization after treatment]. / La tomografia computerizzata nei linfomi: un metodo semplice nel controllo delle localizzazioni addominali dopa trattamento.

The authors, according to their experience of repeated controls of abdominal computed tomography (CT) in 10 patients with Hodgkin's and non Hodgkin's lymphomas, obtained a clear demonstration of therapy response and disease evolution. The reduction or enlargement after therapy of periaortic, pericaval, hepatic, splenic and pancreatic lymph nodes not always opacified from lymphographic contrast medium is evaluated. It was possible, during the same examination, to evaluate liver, spleen, kidneys parenchyma and regional bone. CT results were always well correlated with clinical findings.

[Value of CT and lymphography in the staging of lymphomas (author's transl)]. / Ruolo della tomografia computerizzata e della linfografia nello staging dei linfomi.

The contribution of CT is evaluated in association with conventional diagnostic investigations in the staging of lymphomas. The data obtained by means of CT are an integration of those obtained by means of lymphography. On the other hand CT offers elements which cannot be obtained by others methods, especially concerning the retroperitoneal region. This diminishes the average of patients who must undergo laparoscopy and laparotomy. Moreover CT allows to follow the evolution of the disease and to control the results of the treatment.
