Intralesional injection of OK-432 is an effective treatment modality for macrocystic-type lymphangiomas in the head and neck region. It has no complications, and surgical excision in case of failure is not compromised by fibrosis. Sclerosing of macrocystic-type lymphangiomas with OK-432 should therefore be considered before surgical excision.
In cases of equivocal diagnostic CT, SPECT/CT bridges the gap between MIBG scintigraphy and diagnostic CT, with guidance of the diagnostic CT and characterization of its findings. In this small series, MIBG SPECT/CT increased the diagnostic certainty in 89% of discordant studies.
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.
