Minimally Invasive Treatment for a Sacral Tarlov Cyst Through Tubular Retractors.

Background: Tarlov cysts (TC) are focal dilations of arachnoid and dura mater of the spinal posterior nerve root sheath that appear as cystic lesions of the nerve roots typically in the lower spine, especially in the sacrum, which can cause radicular symptoms when they increase in size and compress the nerve roots. Different open procedures have been described to treat TCs, but no minimally invasive procedures have been described to effectively address this pathology.

Case Description: A 29-year-old woman presented with right lower extremity pain and weakness.

Malignant nerve sheath tumor involving glossopharyngeal, vagus and spinal nerve with intracranial-extracranial extension and systemic metastases in a patient with type 1 neurofibromatosis: A case report.

Introduction: Intracranial malignant peripheral nerve sheath tumors are an extremely rare pathology with a high morbidity and mortality. Epidemiological, clinical and prognostic data are scarce and with little certainty in the literature. The aim of this paper is to report for first time in English literature, the case of a patient with type 1 neurofibromatosis, who presented a malignant peripheral nerve sheath tumor that involved the left glossopharyngeal, vagus and spinal nerves with intracranial and extracranial extension through jugular foramen and systemic metastases.

Traumatic brain injury with a machete penetrating the dura and brain: Case report from southeast Mexico.

Introduction: Traumatic Brain Injury (TBI) is a major cause of death and disability in our society, we present the first case report of non-missile penetrating (NMP) cranial trauma with a machete in Mexico, and our objective by presenting this case is to prove the usefulness of recently proposed algorithms in the treatment of NMP PRESENTATION OF CASE: We present the case of a 47 year old woman who received a machete hit to the right side of her head during an assault., she arrived fully conscious to the emergency department (ED), computed tomography was performed and based on the findings of this study and in accordance to recently proposed algorithms for managing NMP cranial trauma a craniotomy was performed, at follow-up the patient presented wtih minor neurological disability in the form of left hemiparesis.

Discussion: Non-missile penetrating (NMP) lesions are defined as having an impact velocity of less than 100m/s, causing injury by laceration and maceration, An algorithm for treating NMP cranial trauma has been recently published in the Journal World Neurosurgery by De Holanda et al.
