Computed Tomography Imaging Findings of Pulmonary Chondroma

Abstract

Purpose To characterize the computed tomography (CT) imaging findings in patients with pulmonary chondroma. Methods We examined CT imaging findings of eight patients with histopathologically verified pulmonary chondroma. We assessed the location, size, shape, margins, amount of calcification, calcification pattern, and attenuation on precontrast and enhancement CT. Results All patients exhibited solitary, mildly lobulated pulmonary masses, which were located in the right lung in four cases and the left lung in four cases. The mean lesion size was 3.7 cm (range 0.9–10.7 cm). All eight tumours had a well-defined margin. On plain CT images, seven of the cases (87.5%) showed a mass with varying degrees of calcification, which included strip-like punctate (n=5) and ring (n=2) patterns. One patient with a large lesion (10.7 cm) showed chest wall adhesion. On contrast-enhanced CT images, all lesions demonstrated slight inhomogeneous enhancement ≤14 HU. Conclusion CT is the reference standard diagnostic technique for locating pulmonary chondroma. In most cases, CT findings show some characteristics that are important in the diagnosis, surgical planning, and follow-up of the tumour.

Rapidly growing proliferative pulmonary chondroma: A case report

“…The tumour was discovered by an emergency CT scan taken when the patient presented chiefly complaining of cough. Although previous reports have reported cough as a clinical manifestation of pulmonary chondroma [2] , her cough was only coincidental and was not associated with tumour growth or multiplication. Although one report suggests that the growth of pulmonary chondroma is slow [3] , our report showed an increase in both the size and number of the tumours within 2 years.…”

“…Макроскопически имеют включения кальция и ограничены фиброзной капсулой [11]. При рентгенологическом исследовании хондромы легкого визуализируются как округлые образования с четкими фестончатыми контурами смешанной структуры за счет мягкотканого компонента и зон обызвествления [14,15], при этом встречаются различные типы кальцификации: точечные, линейный, в виде колец Рис. 4.…”

“…Contrast-enhanced MDCT of the thorax shows normal postoperative findings 3 months after pneumonectomies [13], в единичном наблюдении хондрома была представлена мягкотканым образованием без кальцинатов [15]. При введение контрастного препарата отмечается умеренное его накопление с максимальным градиентом в венозную фазу до 10-14 HU [15]. При наличии в анамнезе ГИСО хондромы легкого нередко принимают за метастазы.…”
