Approximately 50% are associated with other cerebral developmental disorders. These slow growing benign lesions are usually asymptomatic and rarely require surgery. We report the case of a 37 year old woman presented with signs of raised intracranial pressure. Computerized tomography and magnetic resonance imaging demonstrated a quadrigeminal cistern lipoma compressing the aqueduct of Sylvius. The patient underwent surgery and a distinct plane of cleavage between the lipoma and the adjacent neural structures was found, allowing total removal of the lesion. Postoperatively, the patient was relieved of her original symptoms but developed akinetic mutism which lasted for two weeks. Intracranial lipomas rarely become symptomatic and surgery is seldom required. If the lesion progresses and causes symptoms of raised intracranial pressure or compression of neural structures, surgical intervention is indicated. Total removal should not be attempted unless a plain of cleavage between the lesion and adjacent neural structures is present. Surgical manipulation should be minimised to avoid complications.eninfo:eu-repo/semantics/closedAccessQuadrigeminal cisternLipomaendoscopic surgeryAkinetic mutismIntracranial lipomaHydrocephalusDignosisSeizuresNeurosciences & neurologyLipomaEndoscopic surgeryQuadrigeminal cisternAdultAkinetic mutismBrainBrain neoplasmsCerebellumCorpora quadrigeminaCorpus callosumDecompressionSurgicalEndoscopyFemaleHeadacheHumansIntracranial hypertensionLipomaMagnetic resonance imagingNeurosurgical proceduresSubarachnoid spaceTomography, X-rayComputedTreatment outcomeVomitingArticle0002314522000242-s2.0-2294448469459659912515936197Clinical neurologyNeurosciencesLipoma; Pons Angle; Corpus CallosumAdultAkinetic mutismBrain aqueductCase reportCisterna magnaClinical featureComputer assisted tomographyFemaleHumanIntracranial pressureLipomaNuclear magnetic resonance imagingPostoperative periodPriority journalSurgical technique
