[A case of craniotomy with intermittent tracheal extubation for speech mapping during surgery].

We gave anesthesia for craniotomy in a 54-year-old man with intracranial tumor near the Broca speech centers causing facial nerve palsy and slight allophasis. Nasotracheal intubation was performed after intravenous administration of droperidol 15 mg and fentanyl 0.2 mg.

[A case of dissociative stupor with decorticated posture after neck clipping of brain aneurysm].

We experienced a case of dissociative stupor with decorticated posture in a 71-year-old woman after neck clipping of the brain aneurysm. Decorticated posture is observed with severe midbrain disorder caused by brain herniation. In this case, therefore, severe brain stem damage was suspected, although light reflex was observed and respiration was stable.

Significant gene expression of insulin-like growth factor II and proliferating cell nuclear antigen in a rapidly growing recurrent pituitary acth-secreting adenoma.

Background: We quantified the expression of various growth-related factors in an adrenocorticotropic hormone (ACTH)-secreting adenoma that had recurred very rapidly as invasive macroadenoma.

Methods/results: A 43-year-old woman underwent successful transsphenoidal surgery for Cushing's disease. Seven years later, she was admitted to our ward for further endocrine examinations.

Cerebellopontine angle lymphoma: a case report and review of the literature.

Background: Although malignant lymphomas of the central nervous system have been reported to be increasing in frequency, cerebellopontine (CP) angle lymphoma is rare and only 13 cases have been reported previously in the literature.

Case Presentation: A 63-year-old woman had progressive dizziness and nausea for 2 months. Computed tomography scanning and magnetic resonance imaging (MRI) revealed a mass lesion in the left CP angle, that was compressing the lateral-dorsal aspect of the pons and the fourth ventricle.
