Neuroanatomy
Spinal extradural arachnoid cysts (SEACs) are uncommon spinal lesions that may cause myelopathy, most frequently in the 2nd decade of life. Three contiguous but separate spinal cysts were identified intraoperatively, and they were completely excised with closure of the dural defects. The patient recovered motor and sensory function of the lower extremities.

Pneumorrhachis: The most frequent initial mechanism is an increase in intraalveolar pressure (acute asthma, recurrent vomiting, or closed thoracic trauma). Barotrauma and alveolar rupture allow air migration along the bronchial tree up to the mediastinum. The collected air then separates the mediastinal pleura from the aorta and the parietal pleura from the spine; therefore, it enters the epidural space via the intervertebral foramina. The suddenness, more than the size of the pneumothorax, induces this initial increase in intra-alveolar pressure.

Meet in the middle technique. The neurosurgeon removes the intracranial cyst and sinus tract working through a small bifrontal craniotomy and drilling through the foramen cecum. The plastic surgeon excises the nasal punctum and uses an external rhinoplasty to remove the extracranial lesion.

Illustration showing different locations of brainstem tumors. Midbrain lesions often occur in the tegmentum and tectal plate. The most common pontine lesions are diffuse intrinsic pontine gliomas. Exophytic components may arise from the pontine tumors and protrude into the fourth ventricle. Cervicomedullary gliomas are often low-grade tumors, affecting the medulla and the upper cervical spine.

Endoscope-assisted microsurgery of the posterior fossa. Cerebellum is retracted; retractor not shown. SCA: superior cerebellar artery. SPV: superior petrosal vein. AICA: anterior inferior cerebellar artery. IAM: internal acoustic meatus.
Despite recent technological advances, direct approaches to the posterolateral incisural space remain surgical challenges. The extreme lateral infratentorial supracerebellar approach to treat pathologies located in the ambient cistern and posterior incisural space is a technically feasible route in selected cases.
