ABSTRACT
A prospective study of 622 consecutively registered patients with 650 breast tumors was performed to appraise the reliability of combined physical examination, mammography, and fine-needle puncture (triple test) in the preoperative diagnosis of such tumors. All malignant as well as benign test results were confirmed by subsequent histologic examination. The diagnostic accuracy of the triple test at benign changes is comparable to that of histologic examination, but participation of experienced radiologists and cytologists as well as persons skilled in fine-needle puncture is required. Twenty-eight percent of the planned excisional biopsies were made superfluous by the fine-needle puncture, which immediately revealed the tumor as a cyst, abscess, or hematoma. For this reason, too, fine-needle puncture is recommended as a routine procedure.

A prospective study of 292 consecutive patients with 303 tumours was performed to appraise the combination of physical examination, mammography and fine-needle puncture (triple test) in the diagnosis of breast tumours. The diagnostic accuracy of the triple test was 100%. Because of its relative smallness, however, the series does not permit the conclusion that a benign result of triple test makes excisional biopsy unnecessary. It is emphasized that a follow-up regimen with participation of radiologists and cytologists is required. Fine-needle puncture with cytologic examination of the aspirate is recommended as a routine procedure in the diagnosis of breast tumours.

The clinical value of percutaneous pulmonary aspiration biopsy was assessed in 500 patients. Conclusive information was obtained in 53.6% (i.e. with decisive value in 27.4 and supportive value in 26.2%). Inconclusive results were reported in 44.8% of the cases and in 1.6% the cytologic report was misleading. Pneumothorax occurred in 25% of the series and required intubation in 4.4%. Percutaneous transthoracic fine-needle aspiration biopsy provides a simple means of obtaining positive diagnostic information of pulmonary lesions suspected to be malignant.

The material includes 15 suprarenal and five other retroperitoneal neuroblastomas. All patients were examined by intravenous pyelography which was evaluated with regard to calcification; renal configuration; compression and displacement of the renal pelvis; and renal concentration. It was possible to distinguish between suprarenal and other retroperitoneal neuroblastomas. In five patients the final diagnosis was obtained by selective angiography. Adventitious tumour circulation was not always due to invasion. A brief survey is given of the clinical findings at the time of examination, metastases being present in 75%. Three patients underwent radical surgery, while six were treated conservatively and in 11 patients surgery was either impossible or incomplete. Survival is possible without total removal o the tumour. The survival rate over a five-year period was 30%.

Retrospectively the urographic findings, history, clinical signs and surgical/pathologic features of 46 Wilms' tumours were analysed. Imparied or no function of the kidney was associated with a high incidence of defects of the renal pelvis and invasion of the renal vein. A high rate of non-radically operated or inoperable tumours and high mortality was present in these cases.

Twelve cases of Wilm's tumor were examined: By intravenous pyelography alone in eight children and by pyelography and angiography in four adults. Intravenous pyelography showed characteristic displacement of the calyceal structures and displacement of the renal pelvis. Angiography gave detailed information regarding the vascular supply to the mass, the degree of vascularity, presence and number of tumor vessels and degree of pooling of contrast material in the tumor. Vascular penetration through the capsule of the kidney was not always consistent to perirenal tumor infiltration. By angiography one case of bilateral Wilm's tumor and two cases with metastases were discovered.

Abdominal masses localized to the region of the kidney in the newborn require different diagnostic procedures. Taking advantage of cystourethrography, retrograde and intravenous pyelography and angiography, it should be possible to make the right diagnosis as in our two cases demonstrating renal vein thrombosis.

The heterotaxy syndrome is a rare condition and very often combined with congenital abnormalities or malformations. Studying the bronchial tree on the chest x-ray it is possible to indicate the visceral situs with asplenia or with polysplenia.

A critical evaluation revealed no distinct clinical complex of symptoms related to the radiological picture of chronic adhesive arachnoiditis in the lower lumbar sac in 72 patients. In all cases the arachnoiditis was diagnosed by myelography with water soluble contrast media and, in 16 cases, verified by operation and microscopy. The assumed cause of arachnoiditis was, in more than half of the cases, the combination of myelography and operation in close relation, and, in ten cases, a previous operation.
