ABSTRACT

Occult insulinomas are tumors which are not identified by conventional tests. Selective arterial calcium stimulation and hepatic venous sampling (ASVS) can be used to identify the pancreatic segment where the tumor is located. We report the case of a patient with clinically proven insulinoma detected only by ASVS. The details of the procedure are also discussed.

Keywords: Insulinoma, Pancreas, Arterial stimulation and venous sampling (ASVS)

RESUMO

Insulinomas ocultos são tumores não detectáveis aos exames convencionais. O estímulo superseletivo arterial com cálcio e coleta venosa hepática (EACV) é um exame que pode ser utilizado para localizar o segmento pancreático acometido pelo tumor. Relatamos o caso de uma paciente com insulinoma oculto detectado por meio do EACV. Além disso, são discutidos aspectos técnicos da realização do exame.

Palavras-chave: Insulinoma, Pâncreas, Estímulo arterial com coleta venosa (EACV)
