“…Tumors within the third ventricle in chil dren have been associated with amnesia, confusion, and a fluctuating level of consciousness [23]. In adults, memory impairment, anxiety, and psychosis have been described with third ventricular tumors [44,45], Paramedian tha lamic strokes in adults can cause confusional states. altered level of consciousness, amnesia, and aphasia as well as vertical gaze, motor, and sensory impairments [46].…”

Neurobehavioral Outcome in Pediatric Craniopharyngioma

et al. 1997

Neurobehavioral dysfunction occurs in children with craniopharyngioma, both before and after treatment, and its impact on outcome may not be fully appreciated. Also unclear is whether neurobehavioral outcome relates more to tumor location or surgical factors. We reviewed the records of 20 children with craniopharyngioma who were seen between 1983 and 1995. All children had subfrontal craniotomy and either partial (14 children) or gross total (6 children) resection of their tumors. In addition to traditional neuropsychological testing, we assessed social behavior and school performance using standardized ratings based on family interviews and school records. Over a mean follow-up period of 38 months, only 3 of 20 children had a good outcome in all three categories, and 12 of 20 had moderate or severe impairment in at least one category. Outcome did not differ between those who had partial and those with gross total resection. We conclude that neurobehavioral disorders are common and cause important morbidity in children after treatment for craniopharyngioma. To evaluate these impairments in future outcome studies, standard neuropsychological testing should be supplemented by specific behavioral assessments to capture the full range of neurobehavioral disability. In this series, partial versus gross total resection did not influence outcome, implying that tumor location in diencephalic and limbic regions is a more important factor.

Between 1974 and 1987 19 patients harbouring colloid cysts of the third ventricle have been treated in our department. There were 12 male and 7 female patients with an average age of 34 years (ranging from 17 to 58). Eighteen of the 19 patients underwent direct microsurgical removal of the space occupying lesion using the transcortical-transventricular approach. One patient had placement of a ventriculoperitoneal shunt and declined further treatment. There were no deaths in the entire series and no permanent neurological deficits were observed postoperatively. Surgery was successful in unblocking CSF pathways in 12 patients; six patients required permanent CSF diversion. Considering the advantages and disadvantages of various surgical modalities for the treatment of the lesions we recommend the microsurgical removal of the colloid cyst using the transcortical-transventricular approach.

“…However, psychotic symptoms have also been reported in several cases of obstructive hydrocephalus: Roberts et al 7 found five cases with schizophrenia-like psychoses, presenting with symptoms as delusions, auditive hallucinations or social withdrawal, which were later diagnosed with obstructive hydrocephalus on the basis of Sylvian aqueduct stenosis. Other cases have been reported where patients with obstructive hydrocephalus on the basis of colloid cysts around the third ventricle presented with different psychiatric symptoms as hypomania,8 depressive symptoms,9 10 anxiety attacks11 and delusions 10 11. All cases experienced relief from symptoms on surgical intervention by either shunt or removal of cyst 8–11.…”

Obstructive hydrocephalus caused by colloid cyst presenting as a schizophrenia-like psychosis

2018

This report presents a young woman with psychotic symptoms that were highly suspicious of schizophrenia. Previous attempts of antidepressant therapy of mood symptoms had been ineffective. However, she also presented with discrete signs of an underlying neurological condition, and as a part of the diagnostic workup, neuroimaging revealed ventriculomegaly. She was diagnosed with obstructive hydrocephalus and experienced full remission of psychotic symptoms after neurosurgical intervention with a ventriculoperitoneal shunt. This atypical presentation of obstructive hydrocephalus underlines the importance of neuroimaging in psychiatric differential diagnostics. Otherwise, this young woman had been diagnosed with schizophrenia, instead of organic delusional disorder secondary to a neurological condition, with possible irreversible damage to brain tissue as a consequence.
