RESUMEN
Breast density is a radiological concept based on the proportion of radiopaque glandular tissue relative to radiolucent fatty tissue. Mammographic evaluation of dense breasts is more difficult, related to technical difficulties, with decreased rates for detection and characterization of breast lesions, resulting in reduced sensitivity with increased number of interval cancers at routine follow-up when compared to radiolucent breasts. We will review the definition of dense breasts and their frequency, especially their relationship with the age of patients. We will discuss the current technical problems and the impact of breast density on the efficacy of conventional mammography. We will discuss the value of digital mammography, the role of computer assisted diagnosis (CAD) systems and tomosynthesis in the evaluation of dense breasts.

Peripheral vascular leiomyosarcomas are rare. A case of leiomyosarcoma of the great saphenous vein diagnosed pre-surgically by MRI and fine-needle aspiration is presented. Characteristics of the tumour and imaging features are discussed.

Lingual thyroid is a rare embryologic migration failure. It may undergo goitrous changes and the ensueing complications as well as carcinomatous transformation [1,2]. We describe a case of an infected ossified lingual thyroid goitre with suspicion of carcinomatous transformation.
