    Giant Cystic Craniovertebral Schwannoma Arising From C1 Dorsal Root Masquerading as a Fourth Ventricular Lesion
    (NEUROSURGERY QUARTERLY, 2011) Gopalakrishnan, CV; Baldawa, S; Neelima, R; Nair, S
    Schwannomas that are located at the craniovertebral junction frequently arise from spinal accessory nerve, hypoglossal nerve, and ventral root of C1 or C2. Their origin from dorsal root of C1 is extremely rare. These tumors frequently manifest with pyramidal signs, although rare presentations, such as subarachnoid and subdural bleeds have been reported. Raised intracranial pressure (ICP) occurring due to a giant craniovertebral schwannoma has not been reported to date. The authors report a unique case of a giant cystic craniovertebral schwannoma arising from dorsal root of C1 presenting with raised ICP symptoms, mimicking a fourth ventricular lesion on imaging. The tumor was completely excised by a midline suboccipital approach. This report also highlights the importance of C1 root schwannomas in the differential diagnosis of giant craniocervical junction tumors, especially in those presenting with raised ICP.
