Abstract: The object of this paper was to investigate lipoplastic lymphadenopathy in superficial locations with ultrasound. We selected 110 patients with a total number of 247 nodes with a central hyperechoic area extended for more than one third of the transverse diameter. We considered gender, age, body mass index (BMI), and associated disease such as thyroid disorders and diabetes. For each lymph node, we measured the long:short axis ratio and the parenchyma:fat (P:F) ratio. Differences between mean P:F ratio in diabetic and nondiabetic patients were significant (p = 0.045). Mean P:F ratio was negatively related to BMI (r = 0.62, p = 0.015) and age (r = 0.54, p = 0.024). All of the nodes examined with a mean P:F ratio ≤ 1.2 (58) were found in patients older than 72 y and with a BMI higher than 27.8. Fatty involution may mimic a macrometastasis at palpation and may cause difficulties in US detection. (E-mail: francesco.giovagnorio@uniroma1.it) [Copyright &y& Elsevier]

Arteriovenous intracavernous post-traumatic fistula (FAV) is a rare post-traumatic lesion for which the first choice of treatment is superselective embolization. We present a case of post-traumatic fistula in a 45-year-old patient. The patient underwent penile blood gas analysis and color Doppler ultrasonography and was treated with superselective embolization with an acrylic co-polymer. Postoperative arteriography showed obliteration of the fistula. Color Doppler ultrasonography 60 days after the procedure showed reacquired physiologic patency of the cavernous artery with normal flow parameters. The results of this case confirm superselective embolization as the reference standard treatment of FAV. We propose the use of an acrylic co-polymer as a new, effective embolizing medium.
