Anatomical implications of posterior cephaloceles in the dural venous sinuses.

Objective: To analyze the venous anatomy of the dural sinuses of patients with posterior encephaloceles, in order to formulate anatomical patterns which can ensure safer surgery.

Methods: This is a retrospective study, analyzing eight patients diagnosed with posterior encephalocele throughout 1 year.

Results: Eight patients with cephaloceles were evaluated in our study from January 2017 to January 2018.

A rare cause of thoracic cord compression.

Background: The posterior longitudinal ligament (PLL) extends from the foramen magnum to the sacrum. In some cases, it becomes calcified/ossified; the term for this is ossification of the PLL (OPLL).

Case Description: A 50-year-old female presented with acute sphincter dysfunction and paraparesis attributed to T2-T4 OPLL.
