An arteriovenous malformation is a rare vascular anomaly composed of a complex network of interconnected arteries and veins of the scalp. It is usually congenital, but infrequently occurs after trauma. Over the years, several terms have been used to describe these lesions, such as cirsoid/rasemose/arteriovenous aneurysm, plexiform angioma and aneurysma serpentinum, or arteriovenous fistula when a single connection exists. Head and neck malformations occur in 0.1% of the population. Involvement of the superficial temporal artery is rare, occurring in about 0.5% to 2.0% of cases. They are diagnosed by angiography and can be managed by endovascular or open resection. The case of a 23-year-old man who presented with a pulsatile head mass after blunt trauma 5 years prior is presented. This entity was diagnosed as an arteriovenous malformation supplied by the superficial temporal arteries. He subsequently underwent successful open exploration and resection. The information is presented with the patient's consent.
HighlightsGastrointestinal diverticula, although common, may occur in unusual locations such as the gastric region.Gastric Diverticula usually present with vague abdominal symptoms and a high index of suspicion may be needed to make the diagnosis.Gastric Diverticula may be diagnosed using different modalities with varying results, the gold standard of which is OGD.Careful positioning (supine, left lateral decubitus, Trendelenburg) may augment contrast study findings.Gastric Diverticula are usually asymptomatic and benign but rare cases of serious complications such as perforation, bleeding and malignant transformation have been described.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
