Liver haemangiomas undetermined at grey-scale ultrasound: contrast-enhancement patterns with SonoVue and pulse-inversion US.
2005
The objective of this study was to describe the spectrum of contrast-enhancement patterns of hepatic haemangiomas undetermined at grey-scale ultrasound (US) on SonoVue-enhanced pulse-inversion (PI) US. Twenty patients (11 women, nine men) with 35 haemangiomas (size range: 1-7 cm; mean: 3.1 cm) undetermined at baseline US underwent PI at low M.I. (0.05-0.08) after i.v. injection of SonoVue. All haemangiomas were confirmed by typical helical computed tomography (CT) and/or magnetic resonance imaging (MRI) findings. US examinations were videotaped and then reviewed by two experienced radiologists blinded to the final diagnosis. Readers evaluated by consensus the baseline echogenicity and the d…

Cavernous haemangioma of the external auditory canal: clinical case and review of the literature.
2010
SUMMARY Although benign vascular lesions are frequent in the head and the neck region, clinical evidence of cavernous haemangioma of the external auditory canal is extremely rare; when present, the lesion invades the middle ear space. Herein, a rare case of a soft mass filling the external auditory canal, not involving the tympanic membrane, in a symptomatic 59-year-old male is described. Clinical and audiological characteristics, imaging studies and surgical treatment with histological evaluation are reported, which led to a diagnosis of a cavernous haemangioma. This is only the seventh case described in the literature, to date, not involving the tympanic membrane and the middle ear space.…
Sudden death in adolescence caused by cardiac haemangioma
2009
Primary tumors of the heart in infants and children are rare. The types of heart tumors in pediatric age groups are generally different from those in adults. Cardiac myxoma is by far the most common tumor in adults, but in infants and adolescents the prevalent tumor of the heart is rhabdomyoma. Among benign cardiac tumors, cardiac hemangiomas are rare and often diagnosed post-mortem due to the lack of specific clinical symptoms and signs. We report a case of sudden death due to cardiac hemangioma in an apparently healthy 15-year-old adolescent. The autopsy revealed a cardiac hemangioma located at the apex of the heart; the histopathological examination showed the tumor was a mixed capillary…
