ANTECEDENTES:
Niña de cuatro meses de edad referida para evaluación de una pequeña masa superficial discretamente azulada, probablemente relacionada con telangiectasias. La lesión se localiza en el tejido celular subcutáneo sobre el plano muscular del trapecio izquierdo.
HALLAZGOS SONOGRÁFICOS:

ELASTOGRAFÍA SHEAR WAVE (SWE):
Tras diez mediciones en las áreas hiperecogénicas, se obtiene una mediana de 16.0 kPa con velocidad de 2.31 m/s.

ANÁLISIS E INTERPRETACIÓN:
Sonographic Report — Superficial Lesion in an Infant
BACKGROUND:
A four-month-old female infant is referred for evaluation of a small superficial bluish mass, likely related to telangiectasias. The lesion is located in the
subcutaneous tissue over the left trapezius muscle plane.
SONOGRAPHIC FINDINGS:
Examination with an
18–4 MHz linear transducer demonstrates a superficial oval lesion of mixed and heterogeneous echogenicity, with well-defined margins. It shows a central hyperechoic solid area surrounded by multiple rounded hypoechoic elements. No calcifications are identified. Estimated size: 2.76 × 1.47 cm.

COLOR DOPPLER:
Color Doppler shows a small amount of internal flow.

SHEAR WAVE ELASTOGRAPHY (SWE):
Ten measurements obtained from the hyperechoic areas yield a median stiffness of 16.0 kPa and a propagation velocity of 2.31 m/s.

ANALYSIS AND INTERPRETATION:
Correlation of
grayscale imaging, Doppler features, and SWE values supports the diagnosis of a
superficial infantile hemangioma in the early proliferative phase, consistent with the heterogeneous structure, minimal Doppler flow, and moderate stiffness typical of
proliferative vascular tissue.
