Learning objectives
To discuss some of the most common as well as less frequent hand injuries addressing not only the diagnosis but also the management of specific lesions.
To review the anatomy related to the region of interest for each lesion.
To illustrate these lesions using different imaging modalities,
particularly ultrasound and magnetic resonance (MR) with associated surgical findings in some cases.
Background
Hand injuries are common.
The complexity of the hand and the similarities in clinical presentation of different injuries make understanding of hand anatomy and function as well as knowledge of the spectrum of imaging features indispensable for proper diagnosis and treatment.
This pictorial review will address the imaging findings as common as well as less frequent bone and soft tissue lesions of the hands.
Imaging findings OR Procedure Details
GLOMUS TUMOR
Glomus tumors represent 1- 5% of the soft-tissue tumors in the hand [1,2].
Glomus bodies are present in the stratum reticularis of the dermis throughout the body,
but they are highly concentrated in the digits,
palms,
and soles of the feet.
Up to 75% of the glomus tumors occur in the hand,
and approximately 65% of these are in the fingertips,
particularly in the subungual space [1].
At pathologic examination,
glomus tumors are hamartomas developed from the neuromyoarterial glomus bodies which are highly...
Conclusion
Imaging,
particularly magnetic resonance,
plays an important role in the diagnosis of hand lesions and radiologists should be familiar with the imaging features that may provide prompt recognition and proper characterization of specific injuries.
