The authors report a case of a white four-year-old boy with progressive neurological symptoms due to a brain stem mass lesion identified by computed tomography and magnetic resonance imaging scans. The diagnosis of gliosarcoma was confirmed by histological examination. This rare type of central nervous system tumor affects mainly patients over 40 years of age and is most commonly supratentorial. Only a few cases of gliosarcoma in children have been reported, particularly in the infratentorial region. The epidemiological data as well as the most frequent computed tomography and magnetic resonance imaging findings are discussed.

Hysterosalpingography is a technique used for the evaluation of the uterine anatomy and tubal patency and consequently it is primarily indicated for the diagnosis of infertility. The aim of this study was to establish the prevalence of the abnormalities observed on the hysterosalpingograms of infertile patients. All patients that underwent hysterosalpingographic evaluation in a period of four months were allocated. Of the 48 patients studied, 36 presented primary infertility and 12 presented secondary infertility. The patients with primary infertility presented a higher rate of uterine malformations whereas the patients with secondary infertility presented more often tubal obstruction. There were no significant complications during the hysterosalpingograms. This study demonstrates that hysterosalpingography is very useful for the evaluation of infertility, as it frequently diagnoses relevant abnormalities, it is an inexpensive technique and the complications are very rare.

Multiple symmetrical lipomatosis (Madelung's disease) is a rare disorder characterized by deep accumulation of fat tissue, involving mainly the neck, shoulders and chest. This disease is associated with heavy alcohol intake and it is more common in men of Mediterranean origin. This disease can cause severe aesthetic deformities and progressive respiratory dysfunction. We report a case of a patient with multiple symmetrical lipomatosis and describe the clinical and radiological features of this disorder.
