Telangiectasia capilar y anomalía del desarrollo venoso: una rara asociación / Capillary telangiectasia and developmental venous anomaly: a rare association

A propósito de un caso de asociación de una telangiectasia capilar y una anomalía del desarrollo venoso con localización en la protuberancia, como hallazgo incidental, se realiza una revisión bibliográfica. Las asociaciones establecidas de malformaciones vasculares más frecuentes son las telangiectasias capilares con malformaciones cavernosas, y las anomalías del desarrollo venoso con malformaciones cavernosas. La asociación de una telangiectasia capilar y una anomalía del desarrollo venoso es muy poco frecuente, y con localización en la fosa posterior se ha descrito sólo en dos ocasiones. La asociación entre malformaciones vasculares abre la discusión acerca del papel de la obstrucción del flujo en su patogénesis y la consideración de estas malformaciones en el espectro de una única enfermedad (AU)

We review the relevant literature for a case of capillary telangiectasia associated with a developmental venous anomaly in the pons discovered incidentally. The most common established associations among vascular malformations are capillary telangiectasias with cavernous malformations and developmental venous anomalies with cavernous malformations. The association of a capillary telangiectasia with a developmental venous anomaly is very rare and only two cases affecting the posterior fossa have been reported. An analysis of the associations among vascular malformations leads to a discussion of the role of obstructed flow in their pathogenesis and whether these malformations can be considered a spectrum of manifestations of a single disease (AU)

Imágenes puntiformes hiperintensas en la sustancia blanca: una aproximación diagnóstica / Hyperintense punctiform images in the white matter: a diagnostic approach

La presencia de múltiples imágenes puntiformes hiperintensas en la sustancia blanca (IPHSB) en las secuencias de resonancia magnética (RM) ponderadas en T2 es un hallazgo muy frecuente y, en ocasiones, un reto diagnóstico para el radiólogo. Este artículo pretende, a través de una aproximación a la anatomía de la microcirculación cerebral, así como a estudios de correlación anatomopatológica, simplificar la tarea de interpretación de estas imágenes a partir de la descripción de tres principales patrones de presentación de IPHSB: patrón vascular (PV), que corresponde a lesiones microvasculares, patrón perivascular (PpV), que representa a la enfermedad inflamatoria cuyo paradigma es la esclerosis múltiple (EM), y patrón inespecífico (PI), que suele deberse a enfermedad microvascular. A partir de varios elementos semiológicos en las imágenes de RM se puede determinar un patrón predominante en cada caso y, de este modo, acotar el diagnóstico diferencial (AU)

The presence of hyperintense punctiform images in the white matter in T2 weighted magnetic resonance (MR) sequences is a very common finding and is occasionally a diagnostic challenge for the radiologist. The present article attempts, using an anatomical approach to the brain circulation, as well as from histopathology correlation studies, to simplify the task of interpreting these images from the description of the three main patterns of hyperintense punctiform images in the white matter: vascular pattern, which corresponds to microvascular lesions; perivascular pattern, which represents inflammatory disease of which the paradigm is multiple sclerosis; and a non-specific pattern, which has to be a microvascular disease. From the various semiological elements in the MR images, a predominant pattern can be determined in each case and, in this way, helps in the differential diagnosis (AU)

Calcificación en adenopatías cervicales metastásicas de carcinoma escamoso / Calcification in metastatic cervical adenopathies from squamous cell carcinoma

A propósito de un caso de carcinoma escamoso de hipofaringe con múltiples adenopatías cervicales metastásicas calcificadas, se realiza una revisión bibliográfica.El hallazgo de adenopatías calcificadas metastásicas de carcinoma escamoso de cabeza y cuello es muy poco frecuente. Hasta ahora sólo se ha descrito en 3 publicaciones (AU)

We report a case of hypopharyngeal squamous cell carcinoma with multiple calcified metastatic cervical adenopathies, and we review the relevant literature.The finding of calcified metastatic adenopathies from squamous cell carcinoma in the head and neck is very uncommon; only three cases have been reported to date (AU)
