261 Possible Causes for Hydrocephalus, Obstructive Hydrocephalus, Posterior Fossa Cysts

  • Dandy-Walker Syndrome

    Supplementary air encephalography or sagittal reconstruction of tomograms is necessary to define posterior fossa cysts accurately.[] An adult with asymptomatic Dandy-Walker malformation without hydrocephalus was studied.[] hydrocephalus.[]

  • Cerebellar Hemorrhage

    BACKGROUND: Hydrocephalus is a common complication after spontaneous cerebellar hemorrhage (CH).[] The hematoma in the fourth ventricle was gently removed through the hematoma cavity, followed by thorough saline irrigation to release obstructive hydrocephalus.[] hydrocephalus, and extensive destruction of the occipital bone secondary to cranial metastasis.[]

  • Colloid Cyst of the Third Ventricle

    Nearly half (46.2%) of symptomatic patients presented with hydrocephalus.[] Hydrocephalus was present in 65 (83.3%) patients.[] A magnetic resonance imaging scan showed obstructive hydrocephalus and a third ventricle colloid cyst, which was removed by use of the transcallosal approach.[]

  • Craniosynostosis-Dandy-Walker Malformation-Hydrocephalus Syndrome

    fossa cyst 0007291 Sagittal craniosynostosis Early closure of midline skull joint Midline skull joint closes early [ more ] 0004442 Showing of 14 Last updated: 6/1/2019 If[] , with Dandy-Walker malformation and hydrocephalus.[] In some cases of obstructive hydrocephalus, though, an endoscope can be used to create an opening, called an ostomy, which routes the cerebral fluid around the obstruction[]

  • Neurocysticercosis

    Magnetic resonance imaging revealed cystic enhancing lesions in the brain and cervical region of the spine, with the largest cyst extending from the posterior fossa through[] Intraventricular cysts or arachnoiditis usually cause hydrocephalus in neurocysticercosis but craniocervical junction cysts causing obstructive hydrocephalus are rare.[] Cysts were predominantly located in the posterior fossa (31 patients) and supratentorial basal cisterns (19 patients).[]

  • Aqueduct of Sylvius Anomaly

    fossa arachnoid cysts.[] Code Information Diagnosis Code: 742.3 Short Description: Congenital hydrocephalus Long Description: Congenital hydrocephalus Code Classification: Congenital anomalies (740[] Obstructive hydrocephalus due to a mid brain venous angioma is indeed rare and direct operative intervention is best avoided since it may lead to disastrous consequences.[]

  • Hydrocephalus

    fossa arachnoid cysts.[] Hydrocephalus requires regular and long term follow-up.[] Patients with an intraventricular haematoma with no evidence of obstructive hydrocephalus were also excluded from the study.[]

  • Arachnoid Cyst

    Posterior fossa arachnoid cysts (PFAC) are mostly considered as benign lesions of the cerebellum.[] Arachnoid cysts in the fourth ventricle may cause obstructive hydrocephalus.[] When symptomatic obstructive hydrocephalus develops, CSF diversion is the first aim of surgery.[]

  • Pineal Gland Cyst

    Posterior fossa craniotomy - so they went in from the back of my skull (which is why I still have my hair), endoscopic tube up there and pulled out the cyst.[] Postmortem examination revealed a glial cyst of the pineal gland and evidence of chronic obstructive hydrocephalus.[] My MRI report also states, "An area of isointensity of CSF is present in the posterior aspect of the posterior fossa most compatible with a mega cisterna magna.[]

  • Central Nervous System Cyst

    Interestingly, a large posterior fossa cyst was reported in one other case with an ARX mutation, a missense mutation of exon 2 associated with myoclonic epilepsy. 12 Abnormalities[] François Lechanoine and Giuseppe Cinalli, Hydrocephalus and Arachnoid Cysts, Pediatric Hydrocephalus, 10.1007/978-3-319-31889-9_62-2, (1-111), (2018).[] (See Figures 3, 4 & 5 for a case of Acute Obstructive Hydrocephalus resulting from a Colloid Cyst).[]
