Description of a concurrent thyroid haemangioma and a follicular adenoma.

Abstract

Thyroid gland vascular proliferations pose a challenge to pathologists, radiologists and surgeons. This is illustrated in the case of a 36-year-old woman who underwent a diagnostic thyroid lobectomy for a suspected follicular neoplasm according to cytology. Histological diagnosis confirmed a follicular adenoma as well as a cavernous haemangioma or venous malformation.

Contribution: Thyroid vascular lesions are rare. Evolving nomenclature and application of the International Society for the Study of Vascular Anomalies classification are discussed. Pertinent radiological clues are highlighted to pre-empt the diagnosis and avoid potential surgical complications.
