Primary Cavernous Hemangioma of the Thyroid Gland

Abstract

Hemangiomas are benign vascular tumors that result from the abnormal proliferation of vascular tissue. Thyroid hemangiomas can develop as a result of procedures such as fine needle aspiration or other secondary trauma. Primary thyroid cavernous hemangioma is an extremely rare condition, with only a few reported cases. In this report, we present the case of an 83-year-old woman who complained of progressively worsening symptoms of right neck obstruction. She was undergoing levothyroxine treatment for hypothyroidism, and there was no specific family history of thyroid issues. The patient presented with a goiter and obstructive symptoms, and denied any history of trauma or invasive procedures. Thyroid sonography revealed a 6.21 cm heterogeneous dominant solid nodule in the right lobe. Additionally, a large mixed cystic and 6 cm solid mass was identified in the right lobe on CT scan. Due to the significant size of the mass and the presence of obstructive symptoms, the patient underwent a right thyroid lobectomy without further evaluations. Histologic examination of the specimen revealed a cavernous thyroid hemangioma. This case report presents our experience in diagnosing cavernous thyroid hemangioma.
