[New aspects in ultrasound mammography (author's transl)].

We report about 239 ultrasound examinations of the breast using a new water-tank scanner (U.I.Octoson, Ausonics, Sydney, Australia). A very good tissue differentiation of the brease is caused by a special technique and a high resolution. Beside benign results, typical findings in 49 malignancies are demonstrated ("shadowing", "christmastree-sign") and its value discussed. All ultrasound examinations are correlated to X-ray mammography, thermography, needle-biopsy and patho-histology.

Imprint cytology of core needle biopsy specimens of breast lesions. A rapid approach to detecting malignancies, with comparison of cytologic and histopathologic analyses of 173 cases.

OBJECTIVE: To investigate whether imprint cytology of core needle biopsy (CNB) specimens from breast lesions is a useful method of rapidly obtaining additional diagnostic information and potentially can be used to reduce the number of biopsies needed. STUDY DESIGN: Cytologic analysis was performed on 173 breast lesions and compared with their histopathologic diagnoses (143 malignant and 30 benign). For imprint cytology, one CNB specimen was rolled between two slides and stained with Diff-Quik and Papanicolaou stain. RESULTS: The diagnostic overall accuracy of Diff-Quik stain (Papanicolaou stain) was 95.4% (95.9%), with a sensitivity of 96.5% (97.2%), specificity of 90% (90%), positive predictive value of 97.8% (97.8%) and negative predictive value of 84.3% (87.0%). There was no statistically significant difference between the stains. Histopathologic analysis had an overall accuracy of 97.7%, with a sensitivity of 97.2%, specificity and positive predictive value of 100% and a negative predictive value of 88.2%. CONCLUSION: Imprint cytology of CNBs is a sensitive method of detecting malignancies in breast tumors. Diff-Quik is a rapid and reliable approach that can reduce the number of biopsies. Inadequate and suspicious cases should be evaluated based on complementary diagnostic procedures for breast lesions.

[Persistent cysts of the choroid plexus as sonographic indications of a genetic defect].

In the case of a 29-year-old woman an early SGA (small for gestational age) fetus was detected in her third pregnancy. This fact being already a possible indicator for a genetical defect, the fetus also showed permanent cysts of the Plexus choroideus as a sonographical symptom of a deletion of the chromosome 10 (10 qter). The value of Plexus choroideus cysts sonographically diagnosed during pregnancy is discussed by showing the differential diagnoses, the clinical proceedings in general and specially the indications for a chromosomal analysis.
