“…Tumors located at the CPA account for 5%-10% of all intracranial tumors. Among these, VS is the most common (75%-85%) CPA tumor [5] . VS may be further classified as hypovascular or hypervascular and/or hemorrhagic tumors.…”

Vestibular schwannomas, also known as acoustic neuromas, are benign tumors that arise from Schwann cells near the transition from glial cells to Schwann cells. While most vestibular schwannomas are hypovascular tumors, a small percentage constitute the hemorrhagic and/or hypervascular vestibular schwannomas (HVS) subtype. We describe a case of a 36-year-old female who presented with nausea, vomiting, and an acute decrease in vision in her right eye. Computed tomography of the head demonstrated a hemorrhagic lesion in the right hemisphere with evidence of ventricular effacement. Follow-up magnetic resonance imaging revealed a mass in the right cerebellopontine angle that was hypointense on T1-weighted imaging and mild hyperintense heterogeneous signal on T2-weighted imaging, suggestive of a hemorrhagic vestibular schwannoma. It is important for radiologists to recognize the unique clinical and radiological features of HVS in the initial diagnostic assessment of cerebellopontine angle tumors and to distinguish it from common (hypovascular) vestibular schwannomas and other related pathologies. A preoperative diagnosis of HVS allows clinicians to become familiar with the unique characteristics of the tumor and to devise a feasible operative strategy prior to surgical resection.

“…CPAS arises from the closeness of the CPA to specific CNs. [1][2][3][4][8][9][10]12,13 The presentation includes unilateral hearing loss (most common), speech impediments, imbalance, vertigo, tinnitus, disequilibrium, tremors or slowly progressive deafness, other loss of motor control. CPAS is usually due to an acoustic schwannoma arising from the vestibular nerve.…”

Multiple cranial nerve paresis (MCNP) can occur due to some syndromes, systemic diseases, extracranial and intracranial pathologies. The paresies including cranial nerves III, IV, V, VI, and VII are eye-associated MCNP. The common causes of eyeassociated MCNP often include cavernous sinus syndrome, superior orbital fissure syndrome, orbital apex syndrome, and cerebellopontine angle syndrome. Clinical approach to MCNP includes the careful examination for generalized limitation in various gaze positions, proptosis, decreased corneal and facial sensation, conjunctival injection, ptosis, anisocoria, and cerebellar signs. In this review, we aim to briefly remind the main causes of MCNP associated with the eye.

“…85%), meningioma (10% -15%), and epidermoid tumor (7% -8%) are the most common neoplasms, make up about 5% -10% of all intracranial tumors. Most patients with this disease show hearing impairment and facial nerve dysfunction [1]. And the main treatment measures for neoplasms in this area are observation, radiotherapy, and surgery [2].…”

Objective: To retrospectively analyze the clinical utility of quantitative nursing measures of 10 cases of lower cranial nerves injury after cerebellopontine angle tumors surgery to provide the experience for improving the recovery rate and living quality of these patients. Methods: The clinical data of 10 cases of lower cranial nerves injury after cerebellopontine angle tumors surgery was analyzed. For problems such as dysphagia and dyspnea of these patients, the nursing care focused on strict monitoring, timely oxygen inhalation nursing, posture nursing, ventilator nursing, swallowing function training, etc. Results: After received quantitative care, 10 patients with lower cranial nerves injury after cerebellopontine angle tumors surgery were recovered well, and their symptoms such as dysphagia and dyspnea were gradually improved and safely discharged. Conclusion: Lower cranial nerves injury is one of the serious complications after removal of cerebellopontine angle tumors, which impacts the life and health of patients. Caregivers should accurately understand and analyze the symptoms, and quantitative and targeted nursing measures for posterior cranial nerves injury are helpful in the postoperative rehabilitation of patients and improve their living quality.
