case_images: (A,B) There is a large solid mass about 6*5 cm in size in the right CPA area with ventricular and brainstem compression; (C) After the V-P shunt, CT revealed significant relief of her hydrocephalus; (D) Postoperative magnetic resonance imaging shows complete removal of the tumor.

case_images: Subsequently, a tumor in the cerebellopontine angle region was detected by cranial MRI (Figure 1). Furthermore, the follow-up CT scan showed a significant improvement in her hydrocephalus (Figure 1C). Furthermore, MRI scan indicated the absence of hydrocephalus and cerebella tonsil herniation, and the tumor was completely removed (Figure 1D).
case_images: Pathophysiological changes in the body of a pregnant woman with an vestibular schwannoma. (1) Increased intra-abdominal pressure raises intracranial pressure by causing flow of venous blood into the brain through intra-vertebral venous congestion. (2) Increased intra-abdominal pressure and secondary increase in intrathoracic pressure, resulting in increased intracranial pressure due to obstruction of jugular venous blood backflow. (3) Tumor in the intracranial CPA region causing compression of the cerebrospinal fluid outflow tract, resulting in secondary hydrocephalus and subcerebellar tonsillar herniation. (4) Increased perfusion and sex hormones may be important factors in causing tumor oedema, intratumoural bleeding and accelerated tumor growth. (5) When ICP is elevated, the automatic adjustment of blood pressure further aggravates the gestational hypertension.
