[Cystic pancreas neoplasias].

For the treatment of cystic changes of the pancreas, it is essential to distinguish cysts and pseudocysts from neoplasm. Since clinical parameters are usually not characteristic, only morphologic analysis will prove a diagnosis. Nowadays, the cystic pancreatic neoplasms are described as: microcystic adenoma (rich-in-glycogene cystadenoma), and mucinous cystic neoplasms (cystadenocarcinoma or cystadenoma). Morphology, etiology, clinical findings, and treatment are discussed on 3 cases. The new classification of cystic pancreatic neoplasms is important for prognosis in two aspects: 1) On the clinical finding of a pseudocyst, every surgeon should think of a mucinous cystic neoplasm and look for solid tumours digitally. 2) For the pathologist, any mucinous neoplasm should cause him to analyse such cysts macroscopically and, if possible, also microscopically, to rule out an adenocarcinoma.

[Lymphogranulomatosis: diagnosis by conventional roentgen studies and computed tomography].

Thanks to computed tomography the diagnostics of Hodgkin's disease has improved for both the nodal and the extranodal affection. CT is of special importance to determine an extension along the thoracic wall and to assess a pericardial and vascular invasion. All lymph node groups are visualized by computed tomography, but the structure of the lymph nodes cannot be assessed. In a series of 68 patients suffering from Hodgkin's and non Hodgkin's lymphomas, a retroperitoneal lesion was found by CT in 77% and by lymphography in 90% of cases. Sonography is considered as a complementary method. CT is not very sensitive in case of a spleen and liver lesion. Percutaneous biopsy is recommended for the diagnosis of recurrences and for the assessment of residual tumor tissue.

[Massive tumor embolism as the cause of acute cor pulmonale].

A massive tumor embolism was observed in a 35-year-old patient suffering from a tumor of the urinary bladder. Pulmonary embolism was suspected after echocardiographic demonstration of an acute cor pulmonale. Postmortem examination demonstrated multiple small tumor emboli within the small pulmonary arteries.

[Survey echocardiography. A comparative evaluation of enlarged heart chambers in the echocardiogram and the plain x-ray].

Eighty patients with various types of heart disease were examined by radiography and sectional studies of the heart on the same day. These were compared with 2-dimensional examinations of the chambers during end-diastole. It was found that echocardiography may demonstrate dilated chambers due to a cardiomyopathy where the plain radiograph is entirely normal. Radiographic enlargement of the left side of the heart is not necessarily due to dilatation of the left ventricle, but can also be caused by gross hypertrophy. Echocardiography is indicated for the investigation of cardiac enlargement due to multivalvular disease, cardiomyopathy, combined left and right cardiac insufficiency and the exclusion of pericardial effusions.

[Echocardiographic studies before and after a 100-mile race on 21 female athletes].

Two-dimensional echocardiography can provide better information than conventional radiological volume measurements concerning the amount of hypertrophy and dilatation, which contribute to the cardiac enlargement found in athletes. Linear cardiac measurements in standardised planes were obtained by two-dimensional echocardiography; the findings in 21 women athletes obtained before and after a 100-mile race were compared with a number of normals. All cardiac chambers were found to be equally enlarged and the aortic root and the ascending aorta were dilated. The generalised dilatation of the heart must be due to increased ejection volume in these athletes.
