Abstract
Background: Data on pituitary adenoma (PA) prevalence in Saudi Arabia are scarce.
Objective: To estimate the epidemiology of PA in a well-defined population.
Design: Retrospective analysis.
Setting: Departments of Endocrinology and Radiology at King Fahad Armed Forces Hospital, Jeddah, Saudi Arabia.
Patients and methods: Radiological and hormonal data of patients with pituitary adenoma by MRI were reviewed for the period January 2008 to December 2015.
Main outcome measures: Prevalence of PA and hormonal abnormalities.
Results: Of 537 patients; 249 subjects (46.4%), 70 (28.1%) males and 179 (71.9%) females, were diagnosed to have PA with mean age 36.3 (14.1) years. Microadenoma and macroadenoma were seen in 171 (69%) and 78 (31%) subjects, respectively. Microadenomas were more prevalent than macroadenomas (68.7% vs. 31.3%). Microadenomas were significantly more prevalent in females, 131 (73.2 %) vs. 40 (57.1%) whereas macroadenomas were significantly more prevalent in males, 30 (42.9%) vs. 48 (26.8%) (P < .001 for both comparisons). Patients with microadenomas were significantly younger than patients with macroadenomas (P < .0001). Advanced age was significantly associated with a larger PA size (r=0.39, P < .0002). Three types of hyperfunctioning PA were seen: prolactinoma, somatotroph adenoma, and corticotroph adenoma. Five types of hypofunctioning PA were seen: panhypopituitarism, secondary hypogonadism, growth hormone deficiency, central hypothroidism and central adrenal insufficiency. Non-functioning PA were within normal laboratory hormonal values in 2% of cases.
Conclusion: Our study showed that the prevalence of PA was greater than previously reported. This increased prevalence may have important implications when prioritizing funding for research and treatment of PA.
Limitations: Clustering of cases within the study region might have affected estimates and limited study sample size.
