A Case of Empty Sella Syndrome with the First Clinical Manifestation of Sick Sinus Syndrome.

Abstract

Empty sella syndrome (ESS) is characterized by the herniation of cerebrospinal fluid into the sella, which results in the enlargement of the sella and compression of the pituitary gland. ESS commonly accompanies pituitary dysfunction and abnormal secretion of one or more hormones, which manifests as symptoms like cold intolerance, fatigue, and memory impairment. However, the occurrence of sick sinus syndrome (SSS) in ESS has not been reported. A 66-year-old female patient was admitted to the hospital with complaints of dizziness and fatigue. Electrocardiogram (ECG) revealed sinus arrest, junctional escape rhythm, and a heart rate of 40 bpm. Then, the patient was diagnosed with SSS. Thyroid function test indicated decreased thyroxine levels and slightly elevated thyroid-stimulating hormone levels. Additionally, hyposecretion of cortisol and insulin-like growth factors was observed. Magnetic resonance imaging of the pituitary gland confirmed the diagnosis of ESS. The patient was treated with hydrocortisone and euthyrox, relieving the symptoms of dizziness and fatigue. Thyroid function tests during the follow-up period showed normal hormone levels, and ECG examination revealed no abnormalities.
