A brain stem abscess is a rare and severe medical condition. Here, we present a rare case of a brain stem abscess in a young pregnant woman, requiring acute stereotactic intervention. ⋯ A brainstem abscess is a life-threatening condition with a potentially good outcome if treated adequately.

Intracranial hypertension is a well-known life-threatening complication of bacterial meningitis. Investigations on decompressive craniectomy after failure of conservative management are scarce, but this surgical treatment should be considered and performed expeditiously, as it lowers the intracranial pressure and improves brain tissue oxygenation. Early cranioplasty can further aid the rehabilitation. ⋯ This unique report shows that decompressive craniotomy with duroplasty may be a crucial therapeutic approach in bacterial meningitis with refractory increased intracranial pressure and brainstem compression. Early cranioplasty with a patient-specific implant allowed the early and full reintegration of the patient.

Cavernous malformations (CMs) of the optic chiasm are rare lesions often presenting with acute chiasmal syndrome or a progressive visual loss. The case of a 48-year-old female with an intrachiasmatic CM is presented. ⋯ The clinical, neuroradiological, and intraoperative findings are presented, along with a review of the literature.

Glossopharyngeal neuralgia caused by a complex neurovascular conflict: Case report and review of the literature.
Glossopharyngeal neuralgia (GN) is a rare condition characterized by severe, paroxysmal episodes of pain mainly localized to the external ear canal, pharynx, and tongue, usually caused by a neurovascular conflict between postero-inferior cerebellar artery (PICA) and IX cranial nerve. Sometimes there is also a compression of X c.n. ⋯ The surgical treatment of patients with GN caused by complex neurovascular conflicts can be safely performed with the classical MVD of IX c.n. A double MVD of both IX and X c.n. has a role only in patients presenting symptoms from both nerves. Rhizotomy, in our opinion, has to be avoided in all cases. The authors review the literature concerning GN caused by complex neurovascular conflicts.

Thoracic complications of ventriculoperitoneal (VP) shunts have been extensively reported in the literature. Cerebrospinal fluid (CSF) hydrothorax without catheter migration, however, has been rarely described and poorly understood. ⋯ CSF hydrothorax is a rare thoracic complication of VP shunt placement with no radiographic evidence of shunt migration or malfunction. Postulated mechanisms include limited peritoneal capacity to resorb CSF in children and microscopic communications present in congenital diaphragmatic hiatuses.
