Hypertriglyceridemia is.an es.ablis.ed caus. of pancreatitis. In a cas.-bas.d approach, we pres.nt a review of hypertriglyceridemja and how it can caus. pancreatitis. We outline how to inves.igate and manage s.ch patients. A 35 year old man pres.nted to the emergency department with abdominal pain and biochemical evidence of acute pancreatitis. There was.no his.ory of alcohol cons.mption and biliary imaging was.normal. The only relevant pas. medical his.ory was.that of mild hyperlipidemia, treated with diet alone. Phys.cal exam revealed epigas.ric tendernes., right lateral rectus.pals., lipemia retinalis. bitemporal hemianops.a and a delay in the relaxation phas. of his.ankle reflexes. s.bs.quent laboratory inves.igation revealed marked hypertriglyceridemia and panhypopituaris.. An enhanced CT s.an of the head revealed a large s.pras.llar mas. impinging on the optic chias. and hypothalamus. The patient was.treated s.pportively; thyroid replacement and lipid lowering agents.were s.arted. He underwent a s.cces.ful res.ction of a craniopharyngioma. Pos.operatively, the patient did well on hormone replacement therapy. He has.had no further attacks.of pancreatitis. This.cas. highlights.many of the factors.involved in the regulation of triglyceride metabolis.. We review the common caus.s.of hypertriglyceridemia and the propos.d mechanis.s.res.lting in pancreatitis. The incidence and management of hypertriglyceridemiainduced pancreatitis.are als. dis.us.ed.
