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.

Benign peripheral nerve sheath tumor of digit versus major-nerve: Comparison of MRI findings

“…Various soft tissue masses may be encountered in the digit, and the majority are benign [1,2]. The most common soft tissue masses in the digit are ganglions followed by tenosynovial giant cell tumor (GCT) [3].…”

“…Pain or tenderness are not characteristic of any differential diagnosis [4]. Although uncommon, a peripheral nerve sheath tumor (PNST) of the hand or foot can occur, but PNST in the digit is extremely rare [1,5]. Therefore, PNST is not always included in the differential diagnosis for a soft tissue mass of the digit.…”

“…Bu tetkikler arasında en çok tercih edilen iki yöntem, USG (Ultrasonografi) ve MRG (Manyetik rezonans görüntüleme)'dır. Özellikle MRG, cerrahi tedavide için yol gösterici bir özellik taşımaktadır (6). Tedavi genellikle eksizyonel cerrahiden ibarettir (7,8).…”

Adaptive Bayesian label fusion using kernel-based similarity metrics in hippocampus segmentation

“…Magnetic resonance imaging (MRI) is a dynamic and fastgrowing imaging modality that has been increasingly admitted in research and clinical applications such as detection of subtle or small brain abnormalities and identification of pathological structure conditions, 1,2 monitoring of disease progression, 3 and diagnosis of soft-tissue lesions and inflammatory foci. 4,5 Nonetheless, in cases of neuroimaging, the effectiveness of MRI tools strongly depends on the performed segmentation of associated brain tissues or anatomical structures, for which qualitative expert assessments may become impractical because of increased time and human resource consumption. To name a few applications: the detection of subtle or small brain abnormalities and identification of pathological structure conditions, 1,2 monitoring of disease progression, 3 and diagnosis of soft-tissue lesions and inflammatory foci.…”
