PURPOSE: We set out to describe the modern day management of Lymphocytic hypophysitis (LH) with respect to its diagnosis, treatment and long-term endocrine and visual outcomes. We deliberately included patients with a clinical diagnosis of LH and compared them with those with a histological diagnosis following surgery.
METHODS: A multi-centre observational study was performed. Twenty-two patients were included and studied over a mean follow-up period of 8.6 years (range 4-26 years).
RESULTS: Patients presented with headache (N = 15; 68 %), visual field disturbances (N = 7; 32 %) or a combination of these symptoms (N = 5; 23 %). The time lag between onset of symptoms and diagnosis was <1 month, 1-6 months or >6 months in approximately a third of the patients each, respectively. In two-thirds of the patients (N = 14) LH was diagnosed based on their clinical, biochemical and radiological findings. The surgical cohort (N = 8) was statistically more likely to have presented with larger lesions, with suprasellar extension and greater visual field defects. During follow-up there was improvement in headaches and visual symptoms, but the rate of hypopituitarism as reflected by the need for on-going pituitary hormone replacement persisted. At the 1, 5 and 10 year follow-up there was no significant difference between the medically and surgically managed cohorts in terms of ongoing symptomatology or need for pituitary hormone replacement.
CONCLUSIONS: In the modern era, most patients with LH are diagnosed by non-surgical means and managed medically. There remains a significant time lag between the onset of symptoms and the eventual diagnosis of LH. Despite the considerable morbidity attached to LH, overall prognosis is good.
