Abstract
The terminal ventricle (TV) of Krause is a rare cystic dilation of the central canal of the medullary cone. Due to the limited understanding of its pathophysiology, the optimal management of this condition remains a subject of ongoing discussion. In this article, we report the case of a 43-year-old male who presented with stabbing pain at the thoracolumbar junction for approximately two months. Magnetic resonance imaging of the spine revealed a small fusiform dilation of the ependymal central canal, with a Krause terminal ventricle measuring a maximum transverse diameter of 0.5 cm, located at the level of the medullary cone, which exhibits a low displacement at the L4 level.
