Cervical tuberculosis is a rare pathology, which can clinically look like a cervix cancer. The biopsy re-establishes the right diagnosis. The treatment is medical. The prognosis is primarily the infertility due to frequent associated general genital tuberculosis.
The purpose of this pictorial essay is to describe the different mammographic aspects of residual Lipiodol ultra fluid (LUF) after galactography, and to define some specific patterns, because it may in some cases mimic microcalcifications and give diagnostic problems. The mammograms of 14 patients, aged 32-63 years, presenting LUF residues related to previous galactography, were analyzed retrospectively. In 12 cases the diagnosis was easy because the patients presented a typical pattern on mammography and came with their initial galactography. In 2 cases the diagnosis was more difficult because the patients did not remember the previous injection and the progressive resorption mimicked perfectly intraductal calcification. Benign duct ectasia with inflammatory reaction to foreign bodies were found in 3 cases in which surgery was performed. Lipiodol ultra fluid is no longer used for galactography, but it may persist in breast ducts or cysts for years and seems to still be used in some countries. There are in most cases specific signs enabling the diagnosis.
OBJECTIVE: The purpose of this study was to determine the incidence and the mammographic appearance of polyhedral microcalcifications. MATERIALS AND METHODS: Prospectively, we evaluated screening mammograms in 2000 women for polyhedral microcalcifications. The number of polyhedral microcalcifications on routine and magnification views was established, and a quantitative analysis was done to determine if the shape of the polyhedral microcalcifications varied in the different projections. The ratio between the longer axis (R) and the shorter axis (r) was calculated. RESULTS: Two radiologists detected at least two polyhedral microcalcifications on one projection in 58 (3%) women. The number of polyhedral microcalcifications detected ranged from 2 to 47 (mean, 8.2) for screening mammograms and from 2 to 62 (mean, 13.4) on magnification views. Polyhedral microcalcifications were bilateral in 22 cases, scattered in one breast in 19 cases, segmental in 10 cases, and grouped in a cluster in seven cases. Lateral projections showed more rhombohedral microcalcifications, and craniocaudal projections showed more square microcalcifications. CONCLUSION: The frequency of polyhedral microcalcifications is 3%. The shape of polyhedral microcalcifications varies: craniocaudal views show them to be square and lateral views show them to be rhombohedral.
