Pituitary apoplexy in the aftermath of a SARS-CoV-2 infection: a case series from Amiens University Hospital

Objective Since the outbreak of the COVID-19 pandemic, several cases of pituitary apoplexy (PA) following a SARS-CoV-2 infection have been described in several countries. Here, we describe a case series of PA occurring in the aftermath of a SARS-CoV-2 infection to alert physicians about possible neuro-endocrinological damage caused by the virus that can lead to visual sequelae and hypopituitarism. Design and methods We retrospectively identified all the adult patients treated at Amiens University Hospital between March 2020 and May 2021 for PA confirmed by cerebral imaging and following an RT-PCR-confirmed SARS-CoV-2 infection. Results Eight cases (six women, two men) occurred between March 2020 and May 2021 and were reviewed in this study. The mean age at diagnosis was 67.5 ± 9.8 years. Only one patient had a ‘known’ non-functional pituitary macroadenoma. The most common symptom of PA was a sudden headache. Brain imaging was typical in all cases. Only two patients required decompression surgery, whereas the others were managed conservatively. The clinical outcome was favorable for all patients but without recovery of their pituitary deficiencies. There was no diabetes insipidus. Conclusion This case series, the largest in the literature, reinforces the strength, consistency, and coherence of the association between SARS-CoV-2 infection and PA. Our study provides support for the hypothesis that SARS-CoV-2 may be a new precipitating factor for PA. It is essential that practitioners be alerted about possible pituitary disease due to the virus so that such patients are recognized and appropriately managed, hence improving their prognosis.
