ABSTRACT
Congenital anomalies of the central nervous system comprise a wide spectrum of malformations associated with a wide variety of genetic syndromes and chromosomal anomalies, and they are among the principal causes of morbidity and mortality in infants. Among these anomalies, holoprosencephaly arises from the complete or partial failure of the brain to divide into the cerebral hemispheres. Imaging tests are fundamental for the prenatal diagnosis of holoprosencephaly; the diagnostic process usually starts with sonography and then the findings are refined with fetal MRI. Radiologists need to be familiar with the possible findings because the prognosis varies.

Las anomalías congénitas del sistema nervioso central constituyen un amplio grupo de malformaciones asociadas a una gran variedad de síndromes genéticos y anomalías cromosómicas, y una de las principales causas de morbimortalidad infantil. Dentro de ellas, la holoprosencefalia conlleva un trastorno de la diferenciación del prosencéfalo, con una falta completa o parcial de división entre los hemisferios cerebrales. Para su diagnóstico prenatal es fundamental la realización de pruebas de imagen y el conocimiento de los posibles hallazgos, debido a que su pronóstico es variable, comenzando normalmente con la ecografía y confirmando lo visualizado con la resonancia magnética.(AU)

ABSTRACT
La trombosis parcial segmentaria de cuerpo cavernoso es una enfermedad poco frecuente y de origen desconocido que afecta principalmente a varones jóvenes, cuya presentación característica es la aparición de dolor perineal inexplicable asociado a una masa perineal palpable. Consiste en una trombosis en la porción perineal del cuerpo cavernoso, normalmente unilateral, y se asocia a patologías malignas subyacentes y a factores predisponentes, como los microtraumatismos repetidos. Tras la instauración y la adecuada adherencia al tratamiento conservador, es muy infrecuente la aparición de complicaciones como la disfunción eréctil
Partial segmental thrombosis of the corpus cavernosum is an unusual clinical condition of unknown origin that mainly affects young males, whose characteristic presentation is the appearance of unexplained perineal pain associated with a palpable perineal mass. This entity consists of thrombosis in the perineal portion of the corpus cavernosum, usually unilateral and it is associated with underlying malignant pathologies and predisposing factors such as microtrauma. After the adequate adherence to conservative treatment, the appearance of complications such as erectile dysfunction is very uncommon
