Thumb ultrasound: Technique and pathologies

View Article: PubMed Central - PubMed

ABSTRACT

Ultrasound is ideally suited for the assessment of complex anatomy and pathologies of the thumb. Focused and dynamic thumb ultrasound can provide a rapid real-time diagnosis and can be used for guided treatment in certain clinical situations. We present a simplified approach to scanning technique for thumb-related pathologies and illustrate a spectrum of common and uncommon pathologies encountered.

Giant cell tumor (A-E). Long (A) and short (B) axis ultrasound images along the the dorsal aspect of the base of the thumb show a hypoechoic mass (white arrow) encasing the ECRL tendon with extensor pollicis longus tendon displaced (open arrow in A and D) and radial artery lying deep to the lesion (red arrow). Magnetic resonance imaging show a relatively well-defined lobulated mass lesion (white arrow) appearing hyperintense on coronal PD fat-sat images (C) and hypointense on both T1 (D) and T2 (E) weighted images. (F) H and E stain histopathological photomicrograph (×40)

Figure 18: Giant cell tumor (A-E). Long (A) and short (B) axis ultrasound images along the the dorsal aspect of the base of the thumb show a hypoechoic mass (white arrow) encasing the ECRL tendon with extensor pollicis longus tendon displaced (open arrow in A and D) and radial artery lying deep to the lesion (red arrow). Magnetic resonance imaging show a relatively well-defined lobulated mass lesion (white arrow) appearing hyperintense on coronal PD fat-sat images (C) and hypointense on both T1 (D) and T2 (E) weighted images. (F) H and E stain histopathological photomicrograph (×40)

Mentions: Giant cell tumors (GCT) of the tendon sheath appear as well-defined, hypoechoic masses, predominantly homogeneous, although heterogeneous lesions are described. Color or power Doppler imaging shows internal vascularity, peripheral or central, or a combination of the two. Although the ultrasound appearance [Figure 18] is not diagnostic, the proximity to the tendon sheath is highly suggestive of GCT of tendon sheath.[20]
