Ultrasound characteristics of five common soft-tissue tumours in the hand and forearm

Abstract

The study found 5 key ultrasound characteristics that were important for differentiating the tumours: existence or not of vessels, existence or not of a capsule, echogenicity, echo structure, and pattern of growth. Taking these traits into consideration should make it easier for the examiner to make the right diagnosis with a reasonable degree of accuracy.

Subcutaneous angioleiomyomas: Gray‐scale and color Doppler sonographic appearances

“…All these sonographic features have been reported in the radiological literature favoring the benign nature of the mass. [8][9][10][11]13,15,16 However, specific sonographic descriptions of angioleiomyoma are rare. 8 The 10 tumors in our series showed vascularity on CD and PD examination.…”

“…8,11 Clinically, the major differential diagnoses included localized villonodular synovitis, lipomas, hemangiomas, nerve sheath tumors, and ganglia. [8][9][10][11][13][14][15][16] An accurate sonography can help in differential diagnosis with lipomas and ganglia. [9][10][11][12][13][14][15] However, differentiating between angioleiomyomas and circumscribed haemangiomas, glomic tumors, and neural tumors is not possible on the basis of sonographic features alone.…”

“…9 The CD and PD studies focused on the intralesional vessel density (this parameter was estimated by counting the number of CD signals in an area of 1 cm 2 of the most highly vascularized part of the lesion 10 ) and the detection of vascular pedicles. A spectral Doppler analysis was also performed in 5 cases.…”

An unusual case of a glomus tumor developing in a subcutaneous vein of the wrist

“…[8][9][10] The decrease of acoustic impedance due to the accumulation of densely packed cells explains the homogeneous hypoechogenicity of these lesions. Although color Doppler findings in glomus tumors are still controversial, 8,10,11 the presence of numerous vessels on histopathologic examination explains the hypervascular appearance noted on color or power Doppler sonography. In cases of subungual glomus tumors, however, compression of the mass by the nail and sound attenuation may hamper the obtention of good Doppler signals, resulting in a hypovascular appearance.…”

Use of ultrasound-guided supraclavicular brachial plexus block as an anaesthetic technique in a patient with neurofibromatosis type 1: a case report

“…No neurofibroma was identified as there might not have been any within the sheath or it/they might have been unnoticed because of their hypoechoic nodular sonographic appearances, which is exactly as the brachial plexus trunks/divisions at this level. [8][9][10][11][12] Beggs [9] described neurofibromas as well-defined solid hypoechoic masses that have faint distal acoustic enhancement. Reynolds et al [13] also reported that these tumors are often hypoechoic, with posterior acoustic enhancement.…”
