“…Ultrasound provides additional details such as a characteristic trilaminar hyperechoic structure (Figure 3a), presumably reflecting the longitudinal arrangement of keratin chains. Interestingly, this arrangement resembles the bilaminar structure of the also keratinised ungual plaque of the nail (Figure 3b) [6]. Eyelashes are uniformly monolaminar (Figure 4), perhaps reflecting limitations in the resolution of ultrasound machines (currently 0.1 mm), or microstructural specificities of the keratinous component.…”

ABSTRACT. Disorders of the scalp often result in severe cosmetic interference with quality of life, creating the need for optimal medical surveillance. We tested the latest generation of ultrasound machines in patients with scalp pathology and prepared a cross-sectional library encompassing a wide assortment of conditions. Normative data on the sonographic anatomy of scalp and human hair, and important methodological considerations, are also included. To improve the medical approach to diseases of the scalp, we evaluated colour Doppler ultrasound, a technique already applied to the study of localised lesions of the skin [2]. We screened 12 461 ultrasound examinations performed over the past 8 years at a national skin sonography referral centre, and selected 221 patients (168 male, 53 female) with scalp lesions. Sonograms were also performed on 33 healthy volunteers (31 male, 2 female). We then prepared a pictorial presentation highlighting sonographic characteristics of scalp skin, scalp hair and eyelashes, and archetypal scalp pathology

“…Generalmente afecta a los dedos del pie, en especial al hallux. Al US se observa como una estructura hiperecogénica con sombra acústica posterior, inmediatamente bajo la placa ungueal y conectada con el margen óseo de la falange distal (8) . En nuestra serie sólo tuvimos un caso de hemangioma óseo.…”

“…A continuous hyperechoic line below the nail bed corresponds to the dorsal bony margin of the distal phalanx (fig 1b). Doppler color and power Doppler ultrasound can detect the presence of low-velocity blood flow within arterial and venous vessels in the nail bed (fig 2) [10,13,18].…”

Ultrasonography in psoriatic disease

Psoriasis represents a common, chronic inflammatory disease involving the skin, nails and joints. Nail psoriasis in usually investigated and diagnosed by clinical examination. New insights support ultrasonography as being a non-invasive reliable imaging technique for studying nail and skin involvement in patients with psoriasis. Power Doppler frequency, higher than 10MHz enables a very sensitive detection and semiquantitative assessment of the blood flow at the dermal level and in the nail bed. In this review we will present the main US findings in skin and nail psoriasis, and discuss the importance of ultrasonography in diagnosing and monitoring psoriasis vulgaris.
