54 Possible Causes for Crowding of the Posterior Fossa

  • Cough Headache

    Finally, Chen et al. found that patients with primary cough headache had a more crowded posterior cranial fossa.[link.springer.com] Finally, Chen and co-workers have recently found that patients with primary cough headache are associated with a more crowded posterior cranial fossa, which may be a further[link.springer.com]

  • Hydrocephalus

  • Syringomyelia

    The patient's symptoms gradually disappeared and magnetic resonance imaging studies revealed progressive shrinkage of the syrinx despite persistence of crowding of posterior[ncbi.nlm.nih.gov] fossa structures at the level of the foramen magnum.[ncbi.nlm.nih.gov]

  • Trigeminal Neuralgia

    From this study, we conclude that patients with TN have a more crowded posterior fossa than healthy subjects.[ncbi.nlm.nih.gov] Women had a more crowded posterior fossa than men (85.8%   2.1% versus 84.1%   2.6%; P   .023) in patients with TN.[ncbi.nlm.nih.gov]

  • Macrocephaly

    A distinctive feature in more than half the patients was cerebellar tonsillar herniation associated with rapid brain growth and progressive crowding of the posterior fossa[ncbi.nlm.nih.gov]

  • Cleidocranial Dysplasia

    Computed tomography and MRI studies of the head revealed crowding of the posterior fossa with tonsillar and uncal herniation.[ncbi.nlm.nih.gov] C, On the sagittal T1-weighted magnetic resonance image obtained at 24 days of life, a crowded posterior cranial fossa is seen.[pediatrics.aappublications.org] The MRI revealed brain parenchyma with normal myelination; however, the posterior fossa was crowded with tonsillar herniation and effacement of basal cisterns ( Fig 1 C and[pediatrics.aappublications.org]

  • Costello Syndrome

    Posterior fossa crowding with cerebellar tonsillar herniation (CBTH) was noted in 27/28 (96%), and in 10/17 (59%) with serial studies posterior fossa crowding progressed.[ncbi.nlm.nih.gov] (CS) and posterior fossa crowding.[ncbi.nlm.nih.gov] The individuals with p.G13C had many typical findings including polyhydramnios, failure-to-thrive, HCM, macrocephaly with posterior fossa crowding, and developmental delay[ncbi.nlm.nih.gov]

  • Polymicrogyria

    Conversely, upon review of imaging studies of patients with MPPH, we noted progressive crowding of the posterior fossa and acquired tonsillar herniation, a process deemed[ncbi.nlm.nih.gov]

  • Thunderclap Headache
