[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

We describe threecases of familial periependymal heterotopia consisting in three sisters who, after having seizures in infancy, were submitted toa magnetic resonance (MR) scan that revealed isotense nodules in the cortical grey matter in all the MR sequences.

Heterotopia is the most frequently occurring anomaly affectingcortical development and, of these, the periependymal form is the most common.

[Diagnosis of Anisakis infestation: experience in our environment]. / Diagnóstico de la infestación por Anisakis. Experiencia en nuestro medio.

OBJECTIVES: To characterize the most frequently found radiological findings in intestinal anisakiasis. MATERIAL AND METHODS: The medical records of 14 patients diagnosed with intestinal anisakiasis between 2000 and 2003 in the Hospital Clinico Universitario Lozano Blesa in Zaragoza (Spain) were retrospectively reviewed. The imaging tests and immunological laboratory tests performed in these patients were evaluated. RESULTS: The most frequent reason for seeking medical assistance was right iliac fossa pain. Radiological findings of an inflammatory intestinal process were observed in 60 % of the patients. Seventy-five percent of the patients had eaten raw or insufficiently cooked fish and had eosinophilia; of these 80 % had elevated specific IgE levels. CONCLUSIONS: The incidence of anisakiasis is increasing and consequently knowledge of its most characteristic clinical, radiological and laboratory manifestations is important. The most frequently affected segment of the digestive tract is the ileum. Many patients have symptoms of acute abdomen, mimicking appendicitis or peritonitis. Anisakiasis is a self-limiting process that usually resolves in 1-2 weeks. Consequently, a conservative attitude is advisable to avoid unnecessary surgery.

Diagnóstico de la infestación por Anisakis. Experiencia en nuestro medio / Diagnosis of Anisakis infestation: experience in our environment

Objetivo: Mostrar los hallazgos radiológicos más frecuentemente encontrados en la anisakiasis intestinal. Material y métodos: Se revisan retrospectivamente las historias de 14 pacientes diagnosticados de anisakiasis intestinal entre los años 2000-2003 en el Hospital Clínico Universitario Lozano Blesa de Zaragoza. Hemos valorado las pruebas de imagen y las pruebas inmunológicas de laboratorio practicadas a estos pacientes. Resultados: El motivo más frecuente de consulta fue el dolor en fosa iliaca derecha. Se encontraron signos radiológicos de proceso inflamatorio intestinal en el 60 % de los casos. El antecedente de ingesta de pescado crudo o insuficientemente cocinado y la presencia de eosinofilia se encontraba en el 75 % de los pacientes; la IgE específica frente a anisakis estaba elevada en el 80 % de ellos. Conclusiones: La incidencia de la anisakiasis está aumentando en los últimos tiempos, por lo que resulta importante conocer sus manifestaciones más características, tanto clínicas como radiológicas y de laboratorio. El segmento del tubo digestivo afectado con mayor frecuencia, es el íleon. Muchos pacientes presentan clínica de abdomen agudo, simulando una apendicitis o peritonitis. Se trata de un proceso auto-limitado que suele resolverse en 1-2 semanas, por lo que se debe mantener una actitud conservadora, evitando al paciente una cirugía innecesaria
