A 61 year old man with a several years’ history of chronic pancreatitis and complex partial seizures was referred to endocrinology with low serum thyroid stimulating hormone (TSH).
At the time, examination was normal, and pituitary function tests revealed secondary hypothyroidism and secondary hypogonadism with normal prolactin and normal 9am cortisol.
Magnetic resonance imaging (MRI) of the pituitary gland showed an 8 mm infundibular mass with elevation, but not compression of the optic chiasm. Thyroxine and testosterone replacement were commenced.
His condition was stable for three years, after which he presented with an acute flare of pancreatitis, associated with painful, bilateral exophthalmos (fig 1). He was clinically and biochemically euthyroid on thyroxine replacement. Repeat MRI showed an increase in the size of the infundibular mass, and bilateral extra-ocular muscle expansion with lacrimal gland swelling.
