case_images: Shoulder MRI. (a) T1 FS axial, (b) subtraction T1 FS axial, (c) gadolinium T1 FS axial and sagittal, (d) T1 TSE axial, (e) T2 SPIR axial, and (f) sagittal. Oval axillary mass measuring 4.5 x 2.5 x 1 cm, hypersignal in T2 sequence, and enhanced in T1-gadolinium sequence (white arrow).

case_images: We report the case of a 44 years old woman, who was being followed for a chronic tendinopathy of the right shoulder, in need of a shoulder MRI (Figure 1).
case_images: Axillar Doppler (pictures of (a) row) and sonography (pictures of (b) row). Heterogeneous with hypoechogenic focus, small calcifications, and hypervascularization.

case_images: Ultrasonography (Figure 2) confirmed an oval lesion with regular delimitation, with a heterogeneous aspect comprising a hypoechogenic focus in the caudal portion and small calcifications combined with hypervascularization in Doppler imaging.
case_images: Histological analysis of the excised lymph node. Histological assessment of the lymph node in hematoxylin and eosin (H&E) staining, overview in panel (a). Little residual lymphoid tissue is present, the majority of the lymph node tissue is replaced by a vascular proliferation. Panel (b) shows in more detail in H&E the proliferation of here mainly capillary-like blood vessels lined by inconspicuous vascular endothelium (panel (c), CD31 immunohistochemistry, brown stain denoting positivity).

case_images: The final histological diagnosis of an intranodal hemangioma of CCH type was made following special stains and immunohistochemical confirmation (Figure 3).
