Hemifacial Spasm as the Presenting Manifestation of Type 3c Diabetes Mellitus

Abstract

Background: Type 3c diabetes mellitus (T3cDM) usually occurs because of a variety of exocrine pancreatic diseases with varying mechanisms, which eventually lead to secondary pancreatic endocrine insufficiency i.e. hyperglycemia.

Phenomenology: A man suffering from previously undiagnosed T3cDM presenting with subacute onset hemifacial spasm.

Educational value: This case emphasizes the importance of rapid bedside measurement of capillary blood glucose in patients presenting with acute to subacute onset movements disorders irrespective of their past glycemic status.

Keywords: chronic pancreatitis; hemifacial spasm; pancreatogenic diabetes; type 3c diabetes.
