Laryngeal hemangiomas are classified into an adult and infantile forms. The incidence of laryngeal hemangioma in adults is rare. While infantile hemangiomas are more frequently found in subglottic regions and regress with age, adult hemangiomas occur commonly in supraglottic and glottic regions and they do not regress spontaneously. In this article, we report a case of laryngeal cavernous hemangioma in a 51-year-old male who was treated successfully with endolaryngeal microsurgical technique without any recurrence through one year follow up.
Anastomosis found in the adulthood between the carotid and vertebro-basilar systems, apart from the posterior communicating artery, are extremely infrequent and are due to the persistence of vessels that joined both systems during the fetal period. This carotidvertebrobasilar anastomosis are the trigeminal, otic, and hypoglossal and proatlantal arteries. Persistent trigeminal artery is the commonest of the above mentioned four arteries. The reported incidence is about 0.2%. Patients may be asymptomatic or present symptoms due to low flow of posterior circulation or carotid microembolization from posterior circulation. PTA can cause trigeminal neuralgia. We report in this paper a case of a persistant trigeminal artery found in an adult female with a para pcom aneurysm who had persistent trigeminal artery which was seen in CT angiogram. KEYWORDS: Persistent, Trigeminal artery, Intracranial aneurysm. KEYMESSAGES: Persistent trigeminal represents one of the persistent fetal arteries in cerebral circulation which communicate between internal carotid and vertebro basilar circulation. While pcom artery is the main communicating artery that persists in an adult, persistent trigeminal artery is seen in a few cases.
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.
