Use of DWI in identification of small solid pancreatic focalities (≤ 2 cm).

Incidental finding of pancreatic focalities has increased thanks to a larger use of radiological examinations (Ultrasound, CT). The differential diagnosis between focal inflammatory and heteroplastic disease is frequently complicated by the wide spectrum of lesions and by the aspecificity of clinical and medical history, as well as of imaging findings. MRI is the second level choice of examination thanks to its higher intrinsic contrast resolution and parametric capability (1); furthermore, the use of Diffusion Weighted Imaging (DWI) sequences provides additional diagnostic informations.

Gynecomastia: a common indication for mammography in men of all age.

BACKGROUND AND AIM: Gynecomastia (GM) is the most frequent cause of male breast-related signs and symptoms and represents also the most common indication for mammography (MX) in men. In this article, our 7-year long experience with MX in men suffering from GM is reviewed, and the mammographic features of GM are presented. METHODS: MXs performed in male patients at our institution from January 2009 to January 2016 were retrospectively reviewed and patients with mammographic features of GM were selected. Informed consent was waived by the local institutional review board given the retrospective nature of the study. Mammograms were performed in both cranio-caudal (CC) and medio-lateral-oblique (MLO) views according to diagnostic needs. Clinical and pathologic data were obtained by review of patient charts. RESULTS: 37 males (aged between 13-79 years, mean 59 years) referred for MX at our institution because of palpable lump (31/37; 83.8%), breast enlargement (33/37; 89.2%), tenderness or pain (25/37; 67.6%). Of the 37 patients evaluated, 32 (86.5%) had true GM while 5 (13.5%) had pseudoGM. CONCLUSIONS: The evaluation of GM can be complex but a stepwise approach that starts with careful history taking and physical examination may obviate the need for extensive work-up. In this context, MX has been shown to be an accurate diagnostic tool for detecting GM and should be the first imaging examination to be performed in all clinically suspicious lesions referred for imaging.

Texture analysis in a rare case of tibial intraosseous lipoma.

Intraosseous lipoma is a very rare lesion, accounting for only 0.1% of all primary osseous tumors (1), first described in 1980 (2). This lesion is considered the rarest of benign bone tumors (3); probably it is not the actual incidence because these lesions are frequently asymptomatic and the introduction of cross-sectional imaging, especially MRI, seems to have increased the detection (4). The majority of intraosseus lipomas are in the lower limbs (70%) and the os calcis being the most frequently involved (32%). Most cases reported in literature have an age of 40 years (5). Tumor texture could be measured from medical images that provide a non-invasive method of capturing intratumoral heterogeneity and could potentially enable a prior assessment of a patient. Some Authors recently proposed Texture analysis to characterize musculoskeletal lesions (6). For the first time we measured the tumoral texture from Magnetic Resonance images in tibial intraosseous lipoma in a 29-years-old female.

Endobronchial lipomatous hamartoma diagnosed on computed tomography scan in young new mother-A case report.

INTRODUCTION: Hamartoma is the most common benign lesion of the lung, but endobronchial localisation is rare. Typically occurs between the fifth and seventh decade of life and in literature has never been described in association with pregnancy. PRESENTATION OF CASE: We report the case of a young woman in whom the tumor seems to have an increase of size after two pregnancies in the course of his life. DISCUSSION: The pulmonary hamartoma is the most common benign lesion of the lung, but endobronchial localisation is rare. Early diagnosis and resection of benign endobronchial tumors may avert significant morbidity and prevent distal lung damage. CONCLUSION: Following histological examination reassessment of the clinical history of our patient led us to hypothesize, on the basis of pathophysiological, a rise in the size of the endobronchial lesion given by hormonal stimulation pregnancy-related.
