Prostatic rhabdomyosarcoma is an aggressive tumor predominantly found in children. The present paper reports a case of a 27-year-old-patient who had an extensive lesion invading periprostatic planes, with distant metastases found at the moment of the diagnosis. Imaging findings on ultrasound, computed tomography, magnetic resonance imaging, and positron emission tomography/computed tomography were evaluated and correlated with the ones already described in the literature.

Choroid plexus mass lesions encompass a broad and heterogeneous group of diseases and their simulators. Tumors, infections, congenital anomalies, hemorrhage, cysts and degenerative diseases are some examples of mass lesions affecting the choroid plexus. In this article we review the current literature, describing the imaging findings and illustrating choroid plexus mass lesions with some cases diagnosed at our facility. Despite the inexistence of pathognomonic signs, a careful and systematic evaluation of the imaging characteristics may suggest many etiologies.

Madelung's disease is characterized by the presence of symmetric masses of adipose tissue on the neck, shoulders, arms and the upper trunk. Computed tomography demonstrates characteristic imaging findings, and it is considered to be the method of choice for diagnosis, pre-operative staging, and postoperative follow-up. The authors report the case of a man with typical tomographic findings of Madelung's disease.

OBJECTIVE: To describe the main anatomical variations of the celiac trunk and the hepatic artery at their origins. MATERIALS AND METHODS: This was a prospective analysis of 100 consecutive computed tomography angiography studies of the abdomen performed during a one-year period. The findings were stratified according to classification systems devised by Sureka et al. and Michels. RESULTS: The celiac trunk was “normal” (i.e., the hepatogastrosplenic trunk and superior mesenteric artery originating separately from the abdominal aorta) in 43 patients. In our sample, we identified four types of variations of the celiac trunk. Regarding the hepatic artery, a normal anatomical pattern (i.e., the proper hepatic artery being a continuation of the common hepatic artery and bifurcating into the right and left hepatic arteries) was seen in 82 patients. We observed six types of variations of the hepatic artery. CONCLUSION: We found rates of variations of the hepatic artery that are different from those reported in the literature. Our findings underscore the need for proper knowledge and awareness of these anatomical variations, which can facilitate their recognition and inform decisions regarding the planning of surgical procedures, in order to avoid iatrogenic intraoperative injuries, which could lead to complications.
