“…The appearance of symptoms and signs is usually due to compression of the brain, cranial nerves and obstruction of CSF circulation. Some of the clinical symptoms of cerebellopontine angle arachnoid cysts are headache, ataxia, and eighth cranial nerve palsy 24 . They present fluid density in CT, are well delimited, without internal structure, follow the CSF signal on MRI, displace and compress the adjacent parenchyma, and can festoon the adjacent bone structure.…”

Neurovascular compression (NVC) syndrome is a clinical-radiological condition resulting from direct contact and mechanical irritation of a cranial nerve by a blood vessel. It presents with different clinical syndromes depending on the compromised cranial nerve. Its imaging study is performed by magnetic resonance imaging (MRI), which must include the apparent origin and the cisternal portion of the compromised cranial nerve, for which T2 weighted, angiographic and volumetric (3D) T1 sequences with intravenous gadolinium are used. MRI allows us to corroborate the presence of NVC and its differential diagnoses, in addition to being a therapeutic guide and response to treatment. The objectives of this review are to describe the pathophysiology of the NVC syndrome and its clinical-radiological correlation, and to exemplify the different NVC syndromes through illustrative cases. Both clinicians and radiologists must be familiar with the syndromes secondary to NVC and their imaging findings in order to make an accurate and timely diagnosis.

“…This manifestation may arise secondary to lesions found in the suprasellar, prepontine, third ventricle, or the posterior fossa region. The appearance of cranial nerve palsy and ataxia induced from an arachnoid cyst of the CPA is a rather uncommon finding [4][5][6].…”

Introduction. Arachnoid cysts are benign lesions comprising about 1 % of all intracranial space occupying lesions. The majority are asymptomatic, while surgical intervention, consisting of fenestration, is suggested in the presence of mass phenomena.The aim of the study – to present the case of a patient with arachnoid cysts in the cerebellopontine angle and its treatment.Materials and methods. A 53‑years old female patient was referred to our Department of Neurosurgery for the surgical management of a cerebellopontine angle mass. The patient reported tingling sensation and causalgia of her left hemiface, dysarthria, hoarseness, difficulty swallowing solid food and liquids, tinnitus and pain distributed along the ophthalmic branch of the trigeminal nerve.Results. The patient was subjected to retrosigmoid craniotomy with fenestration of the cyst and concurrent placement of a Torkildsen shunt. No complete resection of the capsule of the cyst was attempted, due to its tight adhesions to the adjacent structures. Postoperatively, there was an improvement in the dysarthria and swallowing of the patient.Conclusions. Cerebellopontine angle cystic lesions while histologically benign, may become clinically apparent due to compression of adjacent structures. Simple fenestration of the cyst may be sufficient for the remission of symptoms.

“…Algunos de los síntomas clínicos de los quistes aracnoidales del ángulo pontocerebeloso son dolor de cabeza, ataxia y parálisis del octavo nervio craneal24 . Presentan densidad líquida en la TC, son bien delimitados, sin estructura interna, siguen la señal del LCR en la RM, desplazan y comprimen el parénquima adyacente, y pueden festonear la estructura ósea adyacente.En general, el uso de TC es suficiente para realizar el diagnóstico de la lesión; sin embargo, la RM, dado su mejor resolución de contraste, permite evaluar la localización anatómica, el tamaño y las estructuras comprometidas25 (Fig.11).…”

El síndrome de compresión neurovascular (CNV) es una condición clínico-radiológica producto del contacto directo y de la irritación mecánica de un nervio craneal por un vaso sanguíneo. Se presenta con distintos síndromes clínicos en función del nervio craneal comprometido. Su estudio imagenológico se realiza mediante resonancia magnética (RM), la cual debe incluir el origen aparente y la porción cisternal del nervio craneal comprometido, para lo cual se usan secuencias T2 pesadas, angiográficas y T1 volumétricas con gadolinio intravenoso. La RM permite corroborar la presencia de CNV y sus diagnósticos diferenciales, además de ser una guía terapéutica y de respuesta al tratamiento. Los objetivos de esta revisión son describir la fisiopatología del síndrome de CNV y su correlación clínico-radiológica, y ejemplificar mediante casos ilustrativos los diferentes síndromes de CNV. Tanto los médicos clínicos como los radiólogos deben estar familiarizados con los síndromes secundarios a una CNV y sus hallazgos imagenológicos para realizar un diagnóstico correcto y oportuno.
