[Persistent primitive trigeminal artery associated to aneurysm of the posterior communicating artery: a case report]. / Arteria trigeminal primitiva persistente asociada a aneurisma de la arteria comunicante posterior. Presentación de un caso.

We report the case of a patient that presented with an intense headache caused by a subarachnoid hemorrhage. Magnetic resonance angiography demonstrated the existence of an aneurysm of the left posterior communicating artery, as well as of a persistent primitive trigeminal artery.

[Giant diverticulum of the colon]. / Divertículo gigante de colon.

The giant diverticulum of the colon is a rare entity first diagnosed by Bouvin and Bonte in 1946. Few cases have been reported in the literature. It is normally located in the antimesenteric border of the sigmoid colon. In most cases it is considered to be an uncommon complication of a common disease: colonic diverticulosis. We present a case of giant diverticulum of the sigma diagnosed in an 80-year-old man and we describe the plain-film and CT findings.

Divertículo gigante de colon / Giant diverticulum of the colon

El divertículo gigante de colon es una rara entidad diagnosticada por primera vez por Bouvin y Bonte en 1946. Desde entonces pocos casos han sido descritos en la literatura. Se localiza habitualmente en el borde antimesentérico del sigma. La mayoría se considera una complicación infrecuente de una enfermedad común, la diverticulosis colónica. Presentamos un caso de divertículo gigante de sigma diagnosticado en un varón de 80 años y describimos los hallazgos en la radiología simple y tomografía computarizada

[Heterotopia as the cause of seizures. A case report of familial periependymal heterotopia]. / Heterotopía como causa de crisis. A propósito de un caso de heterotopía periependimaria familiar.

INTRODUCTION: Cortical development disorders constitute a group of entities resulting from an interruption in the development of the central nervous system. Most of them derive from the stoppage of migration, but proliferation and organisation can also be affected. Heterotopia is the most frequent of all migration disorders. CASE REPORTS: We describe three cases of familial periependymal heterotopia consisting in three sisters who, after having seizures in infancy, were submitted to a magnetic resonance (MR) scan that revealed isointense nodules in the cortical grey matter in all the MR sequences. They were diagnosed as having periependymal heterotopia. The existence of a history of early onset seizures in the family of the mother supported the diagnosis of familial heterotopia. CONCLUSIONS: Heterotopia is the most frequently occurring anomaly affecting cortical development and, of these, the periependymal form is the most common. Periependymal heterotopia may be determined by sex-linked inheritance (X chromosome). It is considered to be one of the most common congenital disorders in familial and early onset epilepsy. MR is the preferred diagnostic technique, since its high resolution allows it to identify and characterise heterotopias.

Introducción. Los trastornos del desarrollo corticalconstituyen un grupo de entidades que son consecuencia de la interrupcióndel desarrollo del sistema nervioso central. La mayoríaderiva de la detención de la migración, pero también pueden verseafectadas la proliferación y la organización. Dentro de los trastornosde la migración, la heterotopía es el más frecuente. Casos clínicos.Presentamos tres casos de heterotopía periependimaria familiar,tres hermanas a las que, tras sufrir una crisis en la infancia, seles realizó sendas resonancias magnéticas (RM), por las que seapreciaron nódulos isointensos a la sustancia gris cortical en todaslas secuencias de RM, y se les diagnosticó heterotopía periependimaria.La existencia de antecedentes en la familia materna de crisisde inicio precoz apoya el diagnóstico de heterotopía familiar.Conclusión. La heterotopía es la anomalía del desarrollo corticalmás frecuente y, dentro de ella, lo es la forma periependimaria. Laheterotopía periependimaria puede venir determinada por unaherencia ligada al sexo (cromosoma X). Se considera uno de lostrastornos congénitos más comunes en la epilepsia familiar y decomienzo precoz. La RM es la técnica diagnóstica que se elige, porsu gran resolución, ya que es capaz de identificar y caracterizar lasheterotopías
