Glomus tumor echocardiography and ultrasound

Ultrasound may be helpful in the preoperative diagnosis of glomus tumor; it provides the localization, size, and shape of tumors as small as 3 mm. Findings on ultrasound suggestive of glomus tumor include a well-circumscribed hypoechoic mass.

• Glomus tumor is diagnosed based on symptoms and physical examination. However, preoperative localization of the tumor is needed in order to determine the size of the lesion ensuring complete resection and avoiding recurrence.^[1]
• Ultrasound may be helpful in the preoperative diagnosis of glomus tumor; it provides the localization, size, and shape of tumors as small as 3 mm.^[1]
• Findings on an ultrasound suggestive of glomus tumor include a well-circumscribed hypoechoic mass.

• The limitations of ultrasound is its inability to distinguish glomus tumors from other hypoechoic masses when the lesion is small, flattened, or includes artifacts generated by the nail.
• High-variable frequency ultrasonography may be helpful for confirming the clinical suspicion and assessing the size and location of the tumor preoperatively.^[2]
  • Ultrasound with high frequency transducers is more useful when it comes to tumors less than 2 mm in size and is in the lateral subungal region.^[3]
