OBJECTIVE: To evaluate the positive predictive value for BI-RADS (Breast Imaging Reporting and Data System) categories 3, 4 and 5, correlating mammographic and histological diagnosis in non-palpable breast lesions. MATERIALS AND METHODS: Analytical-descriptive study of 169 women submitted to stereotactic localization for surgical biopsy of non-palpable breast lesions. Mammographic and histological findings were correlated, analyzing the predictive positive value for each category. RESULTS: Forty-two (24.8%) cases were diagnosed with breast cancer - only one in category 3, 19 in category 4, and 22 in category 5. The positive predictive value for categories 3, 4A, 4B, 4C and 5 were, respectively, 3.4%, 10.3%, 11.3%, 36% and 91.7%. Microcalcifications were the most frequent finding related to malignancy, present in 61.5% of these cases. CONCLUSION: The present study has demonstrated that BI-RADS allows a safe prediction of high suspicion of malignancy in lesions category 5 and low suspicion for category 3. As regards the category 4, the positive predictive value has shown a progressive increase in subcategories A, B and C, demonstrating that this subclassification represents an invaluable contribution for a more detailed and accurate assessment of lesions suspicious for malignancy.

The computerized tomography (C.T.) of 18 pacients with sellar tumours were analysed. The C.T. made before surgery in 6 cases was positive in 3 and the type of tumour suggested by C.T. was confirmed in 3. Twelve pacients had a C.T. investigation after surgery and the examination suggest recurrent tumour in 5. Two of these were re-operated. One pacient with colesteatoma had the recurrent tumour verified by surgery and the other, with a pituitary adenoma during re-operation was noted only cicatricial tissue at sellar region.

The authors present the analysis of 27 computed tomography scans (CT) of 18 children which were divided in three groups according to clinical and tomographic criteria. Group 1 was characterized mainly by epilepsy and calcifications. Group 2 was characterized by intracranial hypertension and several tomographic aspects: edema, cysts and nodules were seen in three patients; hydrocephaly and calcifications were seen in two patients and CT was normal in one patient. Group 3 had patients with epilepsy or headache and variable tomographic patterns. The results are discussed based on the available literature.
