El síndrome de Eagle consiste en una elongación de los procesos estiloides con una calcificación de los ligamentos estilohioideos, uni o bilateral. Característicamente produce una cefalea de localización temporal o retroauricular, que se exacerba con el habla y la masticación, con dolor a la palpación de los pilares amigdalinos. Conocer su forma de presentación clínica y semiológica permite solicitar las pruebas complementarias adecuadas que eviten demoras en el diagnóstico y orientar así el tratamiento correcto.

[Headache secondary to Eagle syndrome: a case report with its distinctive features].

Eagle syndrome consists of an elongation of the styloid processes with calcification of the stylohyoid ligaments, unilaterally or bilaterally. Characteristically, it produces a temporal or retroauricular headache, which is exacerbated by speaking and chewing, with pain on palpation of the tonsillar pillars. Knowing its form of clinical and semiological presentation allows requesting the appropriate complementary tests that avoid delays in diagnosis and thus guide the correct treatment.

Central Stellated Scar Sign: Classic Imaging Finding of Renal Oncocytoma with Radiopathological Correlation.

Oncocytomas are benign tumors, with the classic stellate scar found in up to a third of cases, mainly in large ones. We present the case of a 69-year-old man with a palpable, mobile, and painless mass on the right flank, where abdominal ultrasound and abdominal computed tomography detected the presence of a solid right kidney lesion with a central stellate area in the sinus. Postoperative histological analysis confirmed the presence of oncocytoma with a central stellate scar.

Measurement of the anterior chamber depth and ocular axial length: transpalpebral B-mode ultrasound using an 18-MHz linear probe compared with the IOL Master 500.

Aims: To determine the reliability of transpalpebral ultrasound in B-mode (B-TUS) with a high-resolution linear probe (18 MHz) in estimating both the ocular anterior chamber depth (ACD) and axial length (AL), as well as its agreement with the IOL Master 500 optical biometer.

Material And Methods: Cross-sectional study on 82 eyes of 41 volunteers with no history of eye disease. ACD and AL were determined using B-TUS and the IOL Master 500.

Ocular biometry through fully refocused steady-state magnetic resonance imaging sequence: reliability and agreement with the IOLMaster 500.

Purpose: To evaluate the reliability and agreement between Fully Refocused Steady-State magnetic resonance sequences (FRSS) and the IOLMaster 500 optical biometer for measuring anterior chamber depth (ACD) and axial length (AL).

Methods: In a sample of 32 healthy volunteers, separate observers measured the ACD and AL of both eyes using both techniques (inter-method) and through repeated FRSS measurements (interobserver) and by the same observer (intraobserver). We employed the Bland-Altman method to determine the agreement between FRSS and partial coherence interferometry (using the IOLMaster) and the interobserver and intraobserver variability, providing the limits of agreement (LoA, or mean difference ± 1.
