Thyrolipomas - Prevalence in Computed Tomography and Suggestions for Pragmatic Management.

Gossner J - Pol J Radiol (2015)

Bottom Line: Thyrolipomas were found in 2.8% of patients.Like in this study they seem to be incidental findings lacking clinical relevance.Because of the rare possibility of an thyroid cancer with inclusion of mature fat, sonographic follow-up of incidentally discovered thyrolipomas larger than 15 mm should be suggested.

ABSTRACT

Background: Thyrolipomas seem to be a rare occurrence and until now their prevalence has only been reported in two studies. Because of the known significant geographic variations of thyroid disease, generalizability of these findings is uncertain as well as the management of found thyrolipomas.

Material/methods: Retrospective study of 107 computed tomography scans of the chest of a European inpatient population. A literature review was performed and considerations for pragmatic management were proposed.

Results: Thyrolipomas were found in 2.8% of patients. All thyrolipomas were smaller than 15 mm. In all patients these were incidental findings unrelated to patients symptoms. No secondary signs of malignancy could be detected.

Conclusions: Thyrolipomas are a common finding on cross sectional imaging. Like in this study they seem to be incidental findings lacking clinical relevance. Because of the rare possibility of an thyroid cancer with inclusion of mature fat, sonographic follow-up of incidentally discovered thyrolipomas larger than 15 mm should be suggested.

f2-poljradiol-80-305: Thyrolipoma on computed tomography of the chest in a 70-year-old woman undergoing imaging because of a suspected pulmonary embolism. There is a well-circumscribed fatty mass in the right lobe of the thyroid (arrows).

Mentions: In this series, 3 patients showed a thyrolipoma (2.8%). The lipomas measured 7, 8, and 13 mm. All patients with a lipoma were older than 61 years. Thyrolipomas were only found in women. All thyroid lipomas were incidental findings unrelated to patients’ symptoms. Only one of the three lipomas was reported in the initial report of the scan. One of the thyrolipomas showed a small fatty band connecting it to the adjacent fat tissue (Figure 1), the other two of the lipomas were completely surrounded by thyroid tissue (Figure 2). One patient received three CT scans, the thyrolipoma did not show any growth or change in appearance from 2013 to 2015. No secondary findings suggestive of cancer, like lymphadenopathy or signs of infiltrative growth, were found.
