ABSTRACT
Purpose Pituitary stalk thickening (PST) is a rare disease affecting mainly adults. Pediatric cases are infrequent. The aim of this study is to evaluate the frequency of pediatric patients with PST during the pandemic outbreak of COVID-19 in Chile and compare it with previous data. Methods A retrospective chart review was conducted in patients with PST diagnosed during COVID-19 outbreak. Patients <18 years with pituitary stalk width of 3mm or more at pituitary insertion and/or 4mm or more at optic chiasm were included. In order to characterize and compare these cases with those already published, a review of the literature was performed. Results Nine patients were diagnosed with PST. Seven were girls. Mean age at the onset of symptoms was 10.36 years (2.4-17). Germinal cell tumors (GCT) were diagnosed in 8 patients and Langerhans cell histiocytosis in one. All patients had negative tumor markers, arginine-vasopressin deficiency (AVD) and at least one anterior pituitary hormonal deficit at diagnosis. Diagnoses were confirmed histologically in all patients, and four required a second biopsy. We found a frequency of 4 patients per year with PST due to GCT which is twice the one expected in the same population in Chile. Conclusion A surprisingly high frequency of PST presented during the COVID-19 pandemic among Chilean pediatric patients, being GCT the most frequent etiology. The reasons behind this increase in reported cases are still to be elucidated.
