Background: Intracranial neurenteric cysts (NCs) are extremely rare tumors that more commonly involve the posterior fossa than any other cranial part. While transcranial skull base surgery has been the mainstay of treatment, the utility of endoscopic transnasal surgery (ETS) remains to be established. Case Description: We report a case of a large posterior fossa NC extensively involving the suprasellar region, cerebellopontine angle, and prepontine cistern, which we successfully resected with ETS through a combination of transtubercular and transclival routes. Before surgery, the patient presented with abducens nerve and pseudobulbar palsies, which resolved within 2 weeks postoperatively. The patient remained free from recurrence for 3 years postoperatively. Conclusion: Extended ETS may offer a minimally invasive option for the posterior fossa NC, extensively occupying the ventral space of the brainstem.

ABSTRACT BACKGROUND AND IMPORTANCE: Enterogenous cysts are rare tumors found most commonly in the spine, but they have also been reported intracranially. Cases of enterogenous cysts located within the posterior fossa have traditionally been resected via difficult craniotomies that require prolonged retraction and risk injury to cranial nerves. We describe a method for resection of an enterogenous cyst located anterior to the brainstem via the endoscopic transsphenoidal approach. CLINICAL PRESENTATION: A 37-year-old man was found to have a 2-cm mass anterior to the brainstem during routine screening after a trauma. The mass was located within the prepontine cistern, enhanced with gadolinium contrast, and showed no restrictive diffusion. This lesion was most consistent with an enterogenous cyst. A minimally invasive endoscopic endonasal transsphenoidal transclival approach was performed for gross total resection of the tumor. CONCLUSION: We discuss the endoscopic transsphenoidal approach used for the resection of an enterogenous cyst in the posterior fossa anterior to the brainstem. The transsphenoidal approach provides direct access to lesions in this location using a minimally invasive technique while avoiding excessive brain retraction or injury to cranial nerves. In addition, we provide an updated review of the literature for enterogenous cysts located within the posterior fossa.

PHACE(S) syndrome is an acronym for neurocutaneous disease encompassing the expression of (P) posterior cranial fossa malformations, (H) facial haemangiomas, (A) arterial anomalies, (C) aortic coarctaion and other cardiac defects, (E) eye abnormalities and (S) for sternal malformation or stenotic arterial diseases. We report on a case of PHACE syndrome complete expression with persistent fetal vascular anomalies unusually in a 55-year-old women with large bilateral facial and neck haemangioma and posterior fossa circulation insufficiency.

Background: Sub-occipital craniotomies are used in surgical approaches into the posterior cranial fossa. The inion is used as an extracranial landmark of the torcula in burr hole placement. However, inadvertent damage to the torcula and the related sinuses due to variant intracranial location of the torcula has been reported. This study aimed at determining the position of the torcula in relation to the inion. Method: 40 adult open skulls were obtained and the positional relationship between the inion and the torcula assessed. Results: The torcula was at the same level with the inion in half of the cases (50%), below it in 12 cases (30%), and above in 8 cases (20%). The position above the inion ranged from 0.38 to 2.40 cm and below it from 0.75 to 2.45 cm. Conclusion: The torcula lies either at the level of the inion in only half of the cases. The surgeon should augment this physical landmark with radiographs to avoid iatrogenic injuries. Keywords: Inion, Posterior fossa, Craniotomies

SummaryThe histological characteristics of neoplasms that occur in the posterior cranial fossa can often be predicted by a knowledge of the patient’s age and the specific anatomical location of the tumor. Dividing the posterior fossa into midline, cerebellar fossa and cerebellopontine angle provides a scheme to characterize abnormal accumulations of radioactivity according to their anatomical locations. Midline lesions arise from bases activity on the lateral view and are in the midline on the posterior view. Lesions of the cerebellar fossa may be adjacent to but do not appear to arise from the basal structures and are not in the midline. Cerebellopontine angle tumors are adjacent to and appear to arise from the normal radioactivity at the skull base but lie lateral to the midline. The expected distribution of histological types of neoplasms in each area according to age are discussed.

Object Many authors have concluded that the Chiari malformation Type I (CM-I) is due to a smaller than normal posterior cranial fossa. In order to establish this smaller geometry as the cause of hindbrain herniation in a family, the authors of this paper performed volumetric analysis in a family found to have this malformation documented in 4 generations. Methods Members from this family found to have a CM-I by imaging underwent volumetric analysis of their posterior cranial fossa using the Cavalieri method. Results No member of this family found to have CM-I on preoperative imaging had a posterior fossa that was significantly smaller than that of age-matched controls. Conclusions The results of this study demonstrate that not all patients with a CM-I will have a reduced posterior cranial fossa volume. Although the mechanism for the development of hindbrain herniation in this cohort is unknown, this manifestation can be seen in multiple generations of a familial aggregation with normal posterior fossa capacity.
