title: Soft Tissue Masses of Hand: A Radio-Pathological Correlation.
abstract: 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.
