Description of a concurrent thyroid haemangioma and a follicular adenoma

Liezel Coetzee et al. SA J Radiol. .

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.

Keywords: ISSVA classification; pathology; radiology; thyroid; vascular proliferations.

(a) Transverse view ultrasound image of the thyroid gland shows a well-defined, isoechoic, oval nodule with a thin peripheral halo (orange arrows) in the left lobe. (b and c) Longitudinal view ultrasound. The lesion in the left lobe of the thyroid gland (b) demonstrates predominantly peripheral flow on colour flow Doppler (c).
