ABSTRACT

Fundamento: Dos de las tres formas en que se presentan los quistes intracraneales de la línea media anterior son: cavum septum pellucidum y cavum vergae; estos normalmente desaparecen después del nacimiento, de persistir suelen ser asintomáticos, pero también pueden estar asociados a manifestaciones obstructivas, trastornos psicóticos o alteraciones del neurodesarrollo que demandan de un seguimiento clínico. Objetivo: Reportar el caso de un paciente de 6 meses con persistencia de estructuras del periodo embrionario en posible asociación con retraso del desarrollo psicomotor. Presentación de caso: Por lo infrecuente que resulta en la práctica, se informa el caso de un paciente de 6 meses con una persistencia del cavum septum pellucidum y cavum vergae en el que se destaca la posible asociación del retraso del neurodesarrollo a la persistencia de estas estructuras. El diagnóstico se realizó de forma precoz y se intervino oportunamente. Conclusiones: La presentación del caso aportó evidencias epidemiológicas que favorecen la posible asociación entre la persistencia de estas estructuras embrionarias y el retraso del desarrollo psicomotor.


Background: Two out of the three forms in which intracranial anterior midline cysts present are: These usually disappear after birth; if they persist, they are often asymptomatic, but may also be associated with obstructive manifestations, psychotic disorders or neurodevelopmental disorders that require clinical follow up. Objective: To report a case of a 6-month-old patient with persistence of embryonic period structures in possible association with psychomotor developmental retardation. Case presentation: Because of how infrequent it is in practice, a case of a 6-month-old patient with a persistent cavum septum pellucidum and cavum vergae is reported in which the possible association of neurodevelopmental delay with the persistence of these structures is pointed out. The diagnosis was made in an early manner and it was timely intervened. Conclusions: The case presentation provided epidemiological evidences that encourage the possible association among the persistence of these embryonic structures and psychomotor developmental retardation.

ABSTRACT

ABSTRACT Background: Persistence of cavum septum pellucidum (CSP) and cavum vergae (CV) into adulthood and their association with mood disorders is unknown. Objective: We aimed to assess persistence of these cava in Atahualpa cohort individuals, and their association with clinical depression (as a surrogate of limbic system dysfunction). Methods: Cases were defined as Atahualpa residents aged ≥20 years with CSP and/or CV and paired 1:1 to age- and sex-matched randomly-selected controls. A board-certified psychiatrist (blinded to case-control status) interviewed individuals with the aid of the Patient Health Questionnaire depression module (PHQ-9) to establish a diagnosis of clinical depression. The McNemar's test and conditional logistic regression models were fitted to assess the independent association between persistence of CSP and/or CV and clinical depression (as the dependent variable). Results: Of 1,298 individuals undergoing a head CT, 51 (3.9%) had a CSP and/or CV. The selection process for the nested case-control study on the Atahualpa cohort (after excluding eight missing individuals with midline cava) generated 43 pairs. Nine of 43 case-patients (20.9%) and only two control subjects (4.7%) had moderate-to-severe scores on the PHQ-9 (cutoff ≥10 points). Clinical depression was significantly more frequent among case-patients than controls by the McNemar's test (OR: 8; 95% C.I.: 1.1 - 354.9) and the conditional logistic regression model (OR: 8; 95% C.I.: 1.00 - 63.96). Conclusions: This study provides epidemiological evidence favoring the association between midline cava and clinical depression, supporting their relationship with limbic system dysfunction.


RESUMEN Antecedentes: La persistencia de cavum septum pellucidum (CSP) y cavum Vergae (CV) en adultos y su asociación con trastornos del estado de ánimo es desconocida. Objetivo: Evaluar la persistencia de estas cavidades y su asociación con depresión clínica (como marcador de disfunción del sistema límbico). Métodos: Los casos se definieron como residentes de Atahualpa con edades ≥20 años con CSP y/o CV y se emparejaron 1:1 con controles aleatoriamente seleccionados de acuerdo con edad y sexo. Un psiquiatra (ciego al estado caso/control) entrevistó a los individuos con el módulo de depresión del cuestionario de salud del paciente (PHQ-9) para establecer diagnóstico de depresión clínica. La prueba de McNemar y modelos de regresión logística condicional se utilizaron para evaluar la asociación independiente entre persistencia de CSP y/o CV y depresión clínica (como variable dependiente). Resultados: De 1.298 individuos sometidos a TC de cerebro, 51 (3.9%) tenían un CSP y/o CV. El proceso de selección para el estudio de casos y controles generó 43 pares. Nueve de 43 casos (20.9%) y solo dos controles (4.7%) tuvieron puntajes de moderados a severos en el PHQ-9 (punto de corte ≥10 puntos). La depresión clínica fue significativamente más frecuente entre los pacientes que en los controles mediante la prueba de McNemar (OR: 8; 95% C.I.: 1.1 - 354.9) y la regresión logística condicional (OR: 8; 95% C.I.: 1.00 - 63.96). Conclusiones: Este estudio proporciona evidencia epidemiológica que favorece la asociación entre persistencia de CSP y/o CV y depresión clínica, lo que favorece su relación con disfunción del sistema límbico.

ABSTRACT

Objective To explore the value of the cavum vergae vanishing sign for prenatal ultrasound diagnosis of fetal agenesis of the corpus callosum ( ACC ) . Methods Fifty-one cases of ACC of 20 - 32 gestational weeks were confirmed by MRI or induced fetal autopsy . A random selection of 80 normal fetuses of 20 - 32 gestational weeks were chosed as control group . The displays of the cavum septum pellucidum ( CSP) and the cavum vergae( CV ) in the two groups were observed . Results There were 36 cases of complete agenesis of the corpus callosum ( CACC) and 15 cases of partial agenesis of the corpus callusom ( PACC) in ACC group . In 51 ACC cases ,43 cases were confirmed by prenatal MRI ,while 8 cases were confirmed by postnatal MRI . The comparison of display of CSP and CV between the ACC group and the health group was as follows : ① CSP vanishing rate in ACC group was 70 .6% ( 36/51 ) ,meanwhile the disappearance rate of CSP in the health group was 0 ( 0/80 ) ,the difference between the two groups was statistically significant( χ2 = 77 .870 , P = 0 .000) . ② CV vanishing rate in ACC group was 96 .1% (49/51) , meanwhile the disappearance rate of CV in the health group was 1 .2% ( 1/80) ,the difference between the two groups was statistically significant ( χ2 = 118 .673 , P = 0 .000) . The correlation coefficient between the CV vanishing sign and the occurrence of ACC was 0 .952 ( P = 0 .000) ,while the correlation coefficient between the CSP vanishing sign and the occurrence of ACC was 0 .771 ( P = 0 .000) . There were significant differences in CSP disappearance rate and CV disappearance rate between ACC group and control group at different gestational weeks ( 20 - 24 weeks ,25 - 28 weeks and 29 - 32 weeks) ( all P < 0 .001) . Conclusions The cavum vergae vanishing sign ,as an important indirect sign of fetal agenesis of the corpus callosum ,can be obtained quickly from horizontal transverse section of the cavum septum pellucidum . During the middle pregnancy ,it could be an important prenatal ultrasound screening clue for fetal agenesis of the corpus callosum .

ABSTRACT

Los quistes intracraneales de la línea media anterior se pueden encontrar en tres formas: cavum septum pellucidum, cavum vergae y cavum velum interpositum. El cavum vergae es una extensión del cavum septum pellucidum en dirección posterior a las columna del fórnix y el foramen de Monro. Aunque no está presente en todos los fetos, cuando se observa durante la evaluación ecográfica prenatal puede ser mal diagnosticado como un quiste de la línea inter-hemisférica con pronóstico incierto. Se presenta un caso de una embarazada de 18 años quien acudió a la consulta prenatal a las 32 semanas. Durante la evaluación ecográfica se halló una lesión quística eco-negativa de 20 x 12 milímetros de diámetro, rectangular, intracraneal, presencia de cuerpo calloso y sin evidencia de hidrocefalia compresiva. El cariotipo fue normal. Se consideró el diagnóstico de quiste del cavum vergae. Se obtuvo un recién nacido normal posterior a parto vaginal espontáneo. La resonancia magnética después del parto confirmó el diagnostico.


Anterior midline intracranial cysts may be found in three forms: cavum septum pellucidum, cavum vergae, and cavum veli interpositi. Cavum vergae is an extension of the cavum septum pellucidum heading in a posterior direction, past the anterior pillars of the fornix and the foramina of Monro. Although not present in all fetuses, it may be misdiagnosed as a cyst of the interhemispheric line during prenatal ultrasound evaluation, with an uncertain prognosis. We report the case of an 18-year-old pregnant woman who attended to prenatal consult at 32 weeks. Ultrasound evaluation found a rectangular, intracranial, eco-negative cystic lesion, 20 mm wide and 12 mm long, as well as presence of corpus callosum, and no features of compressive hydrocephalus. All cerebral structures were normal. Karyotype was normal. Diagnosis of cavum vergae cyst was considered. A normal newborn was obtained after spontaneous vaginal birth. Magnetic resonance after birth confirmed the diagnosis.

ABSTRACT

El septum pellucidum es un fino tabique formado por dos láminas gliales dispuestas entre el cuerpo calloso en dirección cefálica y el trígono ubicado caudalmente. Durante la vida embrionaria existen variantes anatómicas del septum pellucidum que se disponen en sentido rostro-dorsal. Estas son el cavum del septum pellucidum, el cavum vergae yel cavum velum interpositum. Su presencia o ausencia puede estar relacionada con alteraciones del desarrollo del sistema nervioso y trastornos cognitivo-psiquiátricos, por lo que deben conocerse bien para evitar diagnósticos erróneos


Septum pellucidum consists of a two thin laminae situated caudal to the corpus callosum and cephalic to the fornix (trigonum). Anatomical variations of septum pellucidum appear during fetal life in the ventro-dorsal position. These variations are: cavum septi pellucidi, cavum vergae and cavum veli interpositi. The presence or absence of these cavities can be related to the presence of nervous system or neuropsychiatric dysfunction, therefore they have to be well known to avoid a wrong diagnoses
