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.[ncbi.nlm.nih.gov] An adult with asymptomatic Dandy-Walker malformation without hydrocephalus was studied.[ncbi.nlm.nih.gov] hydrocephalus.[ncbi.nlm.nih.gov]

  • Cerebellar Hemorrhage

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

  • Colloid Cyst of the Third Ventricle

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

  • Craniosynostosis-Dandy-Walker Malformation-Hydrocephalus Syndrome

  • 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[ncbi.nlm.nih.gov] Intraventricular cysts or arachnoiditis usually cause hydrocephalus in neurocysticercosis but craniocervical junction cysts causing obstructive hydrocephalus are rare.[ncbi.nlm.nih.gov] Cysts were predominantly located in the posterior fossa (31 patients) and supratentorial basal cisterns (19 patients).[ncbi.nlm.nih.gov]

  • Aqueduct of Sylvius Anomaly

    fossa arachnoid cysts.[neuropathology-web.org] Code Information Diagnosis Code: 742.3 Short Description: Congenital hydrocephalus Long Description: Congenital hydrocephalus Code Classification: Congenital anomalies (740[healthprovidersdata.com] 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.[neurologyindia.com]

  • Hydrocephalus

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

  • Arachnoid Cyst

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

  • 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.[ehealthforum.com] Postmortem examination revealed a glial cyst of the pineal gland and evidence of chronic obstructive hydrocephalus.[ncbi.nlm.nih.gov] 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.[healthboards.com]

  • 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[jnnp.bmj.com] François Lechanoine and Giuseppe Cinalli, Hydrocephalus and Arachnoid Cysts, Pediatric Hydrocephalus, 10.1007/978-3-319-31889-9_62-2, (1-111), (2018).[doi.org] (See Figures 3, 4 & 5 for a case of Acute Obstructive Hydrocephalus resulting from a Colloid Cyst).[neurosurgerydallas.com]
