IntroductionThis meta-analysis was performed to analyze the clinical presentation, magnetic resonance imaging (MRI) characteristics, and the management of lymphocytic hypophysitis (LYH).Material And MethodsFour different databases were searched from January 2010 to December 2020, two researchers independently conducted literature screening, data extraction, and quality evaluation. We used a random effects meta-analysis to calculate summary relative risks with 95% CI.ResultsThis meta-analysis showed that the percentage of women among LYH patients was 78%. LYH was associated with pregnancy in 15% of female patients, with headache (49%) and symptoms of central diabetes insipidus (CDI) (45%) being the most frequent presentation. In 24% of LYH patients, there was an association with another autoimmune disease. The incidence of secondary hypogonadism, secondary hypoadrenalism, secondary hypothyroidism, and growth hormone deficit was 54%, 49%, 43%, and 22%, respectively. Pituitary contrast enhancement (63%), symmetrical pituitary enlargement (60%), thickening of the pituitary stalk (58%), sella mass or suprasellar extension (58%), and loss of posterior pituitary hyperintensity (50%) were typical MRI findings. Regarding LYH treatment, the percentage of patients who had observation or hormone replacement, steroid therapy, and surgery was 43%, 36%, and 34%, respectively.ConclusionsIt is of great significance to fully understand the clinical characteristics of lymphocytic hypophysitis, reduce missed diagnosis and misdiagnosis, avoid unnecessary surgery and maintain normal pituitary function.Copyright: © 2021 Termedia & Banach.
