  • Endoscopic transtubular resection of a colloid cyst. Neurosciences Ajlan, A. M., Kalani, M. A., Harsh, G. R. 2014; 19 (1): 43-46


    Colloid cysts, benign outgrowths from the roof of the third ventricle, warrant resection when they become symptomatic. Historically, this has been performed by craniotomy and a transcortical or a transcallosal approach that employs a pair of fixed blade retractors and an operating microscope. Less invasive endoscopic techniques have employed rigid endoscopes with single or dual working channels. We report the use of a tubular retractor as a transcortical port to resect a third ventricular colloid cyst. A 29-year-old woman presented with headache. The brain imaging demonstrated a third ventricular colloid cyst. We describe transcortical, transforaminal resection of a colloid cyst using stereotactically guided placement of a tubular retractor, endoscopic visualization, and bimanual dissection with traditional microinstruments. The increased range of viewing angles of the endoscope within the cylinder of access maintained by the tubular retractor facilitates resection of the cyst through a smaller opening.

  • Deep venous structures distortion in spontaneous intracranial hypotension as an explanation for altered level of consciousness. BMJ case reports Ajlan, A. M., Al-Jehani, H., Torres, C., Marcoux, J. 2013; 2013


    Spontaneous intracranial hypotension (SIH) is a syndrome of low pressure headache associated with low CSF pressure. The condition is generally considered benign but extreme cases of SIH can lead to changes in the level of consciousness. We describe a case in which alteration in the level of consciousness was prolonged and severe, and could not be explained solely by the presence of subdural collections. MRI of the brain showed evidence of impaired venous flow secondary to brain sagging causing distortion of deep venous structures.
