Spontaneous thyroid cyst hemorrhage - a case report.

The prevalence of thyroid nodules in the population ranges from 24.83% to 44.4%, with a notable increase observed in patients over 80 years of age, reaching up to 79.8%. In 0.7% to 1.59% of cases, patients presenting with spontaneous thyroid cysts or node hemorrhage require surgical intervention. The present report details a case of a 37-year-old woman who was admitted to the hospital with complaints of cervical pain on the left side of the neck, weakness, and a palpable mass on the anterolateral surface in the lower third of the neck on the left. The mass required aspiration and hemithyroidectomy. The case demonstrates the efficacy of point-of-care ultrasonography (USG) and cyst aspiration as initial steps in the process of decompression. However, it is imperative to exercise caution and meticulous monitoring of the patient, as the necessity for urgent or elective surgical intervention remains a possibility. Furthermore, it is imperative to perform elective surgery, as histological examination of thyroid glands post-hemorrhage reveals malignancy in 5.1-66.7% of cases.
