  2. Susac's syndrome - Wikipedia

    en.wikipedia.org/wiki/Susac's_syndrome

    In a recent analysis (Susac et al., 2003), MRI images from 27 patients fulfilling the diagnostic criteria of Susac's syndrome were reviewed. Multifocal supratentorial lesions were present in all patients. Most lesions were small (3 to 7 mm), though some were larger than 7 mm. All 27 patients had corpus callosum lesions. These all had a punched ...

  3. Cerebellar tentorium - Wikipedia

    en.wikipedia.org/wiki/Cerebellar_tentorium

    The free border of the tentorium is U-shaped; it forms an aperture - the tentorial notch (tentorial incisure) - which gives passage to the midbrain.The free border of each side extends anteriorly beyond the medial end of the superior petrosal sinus (i.e. the apex of the petrous part of the temporal bone [citation needed]) to overlap the attached margin, thenceforth forming a ridge of dura ...

  4. Supratentorial region - Wikipedia

    en.wikipedia.org/wiki/Supratentorial_region

    The supratentorial region contains the cerebrum, while the infratentorial region contains the cerebellum. Although the Roman era anatomist Galen commented upon it, the functional significance of this neuroanatomical division was first described using ‘modern’ terminology by John Hughlings Jackson , founding editor of the medical journal Brain .

  5. Glioma - Wikipedia

    en.wikipedia.org/wiki/Glioma

    The supratentorial is above the tentorium, in the cerebrum, and mostly found in adults (70%). [59] The infratentorial is below the tentorium, in the cerebellum, and mostly found in children (70%). [59] The pontine tumors are located in the pons of the brainstem. The brainstem has three parts (pons, midbrain, and medulla); the pons controls ...

  6. Cerebellopontine angle syndrome - Wikipedia

    en.wikipedia.org/wiki/Cerebellopontine_angle...

    Lesions in the area of cerebellopontine angle cause signs and symptoms secondary to compression of nearby cranial nerves, including cranial nerve V (trigeminal), cranial nerve VII (facial), and cranial nerve VIII (vestibulocochlear). The most common cerebellopontine angle (CPA) tumor is a vestibular schwannoma affecting cranial nerve VIII (80% ...

  7. Tuberculoma - Wikipedia

    en.wikipedia.org/wiki/Tuberculoma

    They occur most often as solitary, infratentorial lesions in young children. [3] In contrast, lesions are most often supratentorial in adults. [3] Pulmonary tuberculomas are among the most common benign nodules, with 5%-24% of all resected nodules being of tuberculous origin. [21]

  8. Choroid plexus papilloma - Wikipedia

    en.wikipedia.org/wiki/Choroid_plexus_papilloma

    With a median age upon diagnosis of 3.5 years, this lesion is often a disease of infancy. They often reside supratentorial in the lateral ventricles of infants (most commonly in the atrium). [4] The fourth ventricle in adults is the optimum location. [5] Adults rarely have it at the cerebellopontine angle. [4]

  9. Central nervous system primitive neuroectodermal tumor

    en.wikipedia.org/wiki/Central_nervous_system...

    Symptoms involve emotional, visual, motor, and speech defects. [2] Magnetic resonance imaging (MRI) and computed tomography (CT) are used to diagnose PNETs. [2] Even though a universal treatment plan hasn't been stablished yet, common strategies involve chemotherapy and radiotherapy for individuals older than 3 years of age.
