Computed Tomography Imaging Findings of Pulmonary Chondroma

Table 1

Clinical and CT imaging findings in eight patients with an pulmonary chondroma.

Patient/age/gender	Location	Maximum diameter; (cm)	Shape	Margin	Attenuation; (plain CT)	Calcification Pattern and grade	Enhancement Attenuation; (arterial)	Enhancement attenuation; (venous)	Enhancement pattern
1/57/F	right middle lob	5.4	mild lobulated	well-defined	39HU	Ring/ 3
2/49/F	right lower lobe	2.9	mild lobulated	well-defined	25HU	strip-like, punctate/ 1	31HU; EV=6HU	37HU; EV =12HU	inhomogeneous enhancement
3/45/M	left lower lobe	4.2	mild lobulated	well-defined	27HU	strip-like, punctate/ 1	36HU; EV =9HU	41HU; EV =14HU	inhomogeneous enhancement
4/59/M	right upper lobe	1.3	mild lobulated	well-defined	21HU	strip-like, punctate/ 1	27HU; EV =6HU	32HU; EV =11HU	inhomogeneous enhancement
5/73/M	left lower lobe	1.1	mild lobulated	well-defined		strip-like, punctate/ 1	29HU	35HU	inhomogeneous enhancement
6/62/F	left upper lobe	0.9	mild lobulated	well-defined	19HU		29HU; EV =10HU	33HU; EV =14HU	inhomogeneous enhancement
7/47/F	right upper lobe	2.8	mild lobulated	well-defined	22 HU	strip-like, punctate/ 1	25HU; EV =3 HU	30HU; EV =8 HU	inhomogeneous enhancement
8/53/F	left lower lobe	10.7	mild lobulated	well-defined	43HU	Ring/ 3

Note: EV: enhancement value=the attenuation value in enhancement CT-the attenuation value of precontrast CT.
