Fibroadenomas and breast carcinoma: a possible answer to a frequently asked question. A pictorial essay.

Fibroadenomas (FAs) are the most frequently encountered benign breast lesions in young women and due to the age of the patients, they are usually diagnosed by ultrasound. Although they rarely undergo malignant transformation, the patients remain concerned about the possibility of malignant transformation. The aim of this pictorial essay is to illustrate the appearance of classic and complex fibroadenomas, to discuss the risk factors and to highlight the imaging characteristics that raise the suspicion of malignant transformation. In other words, we try to answer, according to our experience and literature data, to a frequently asked question in daily practice: "Is there any risk thatmy fibroadenoma will become malignant?"

Breast cystic lesions: Not so simple after all? An ultrasonographic tactical approach.

A wide spectrum of breast diseases breast diseases have or exhibit at some point in their natural history a complex cystic aspect. Through the lens of B-mode and Doppler ultrasound with sonoelastographic augmentation, conditions ranging from the utterly benign fibrocystic change to the most intricate encysted or cystically degenerated cancerous lesions, are covered in detail in this review. The aim of this paper is to familiarize the practitioner with the ultrasonographic aspects of complex breast cystic masses and to implement a gradual, strategic approach in the diagnostic algorithm.

MRI as indicator of pulmonary tuberculosis activity: from morphological to molecular level assessment - a case report.

We present the case of an adult patient with active post-primary pulmonary tuberculosis (TB) and discuss specific morphological and textural aspects found at high-field magnetic resonance imaging (MRI) of the lung. The 42-year-old man, heavy smoker, undertook a routine employment medical examination and was admitted to a referral pulmonology and TB center due to the abnormal findings seen on his chest radiography. The patient presented nonspecific symptoms, bilateral bronchial breath at pulmonary auscultation, inflammatory syndrome on the laboratory blood tests and positive sputum smears for acid-fast bacilli, which together with the typical aspect on the chest radiography lead to a diagnosis of post-primary pulmonary TB and administration of specific medication. To exclude a possible lung cancer and to reevaluate the extent of the disease, computed tomography and magnetic resonance imaging of the lung were performed. The magnetic resonance examination showed, with an accuracy similar to that of computed tomography, the morphology of active post-primary parenchymal TB lesions, as depicted on the T2-weighted acquisition. Moreover, the T1-weighted sequence using iterative decomposition allowed the assessment of both lipid and caseous pneumonia. To the best of our knowledge, this is the first reported case to assess post-primary pulmonary TB using high field MRI equipment, with an analysis from a morphological to a molecular level. By using a fast two-sequence protocol, both morphological, through T2-weighted acquisition, and textural information such as fat content, using dedicated T1-weighted sequence, can be obtained.
