Soft Tissue Masses of Hand: A Radio-Pathological Correlation

الملخص EN

Aim.

To evaluate soft tissue masses of the hand with magnetic resonance imaging (MRI) and ultrasonography (USG) and to correlate imaging findings with pathological findings.

Material and Methods.

Thirty-five patients with soft tissue masses of the hand were evaluated with high resolution USG and contrast enhanced MRI of the hand, prospectively over a period of 2.5 years.

The radiological diagnosis was then compared with cytology/histopathology.

Results.

There were a total of 19 (55%) females.

The mean age was 27.45 ± 14.7 years.

Majority (45%) of cases were heteroechoic.

Four cases were predominantly hyperechoic.

These were later diagnosed as lipomas.

Four cases were anechoic (diagnosed as ganglions).

Only four lesions showed hyperintense signal on T1-weighted images.

Out of these, 3 were lipomas and one was cavernous haemangioma.

Three lesions were hypointense on T2-weighted images.

All these lesions were diagnosed as giant cell tumor of the tendon sheath.

A correct diagnosis was possible on MRI in 80% of cases n=28.

Conclusion.

MRI provides specific findings for diagnosis of certain soft tissue lesions of the hand.

Ultrasonography allows accurate diagnosis of hemangioma/vascular malformations.

However, in most conditions, imaging findings are nonspecific and diagnosis rests on pathologic evaluation.
