Tentorial dural arteriovenous fistula with perimedullary venous drainage-associated cervical myelopathy: illustrative case.

Background: Tentorial dural arteriovenous fistulas (DAVFs) with perimedullary venous drainage causing cervical myelopathy are very uncommon conditions with an extremely aggressive behavior. When the characteristic radiological clues are missing, the unspecific clinical picture may cause delay and make the diagnosis challenging.

Observations: Here the authors report a case of a 58-year-old man who developed progressive spastic tetraparesis and dyspnea with an extensive mild enhancing cervical cord lesion initially oriented as a neurosyphilis-associated transverse myelitis.

Anaplasic ganglioglioma: Cervical-dorso-lumbar leptomeningeal dissemination. About a case.

Gangliogliomas are well-differentiated, slow-growing tumors. The majority are gradeI of WHO. It appears predominantly in children and young adults.

[The effect of age on the prognosis of patients with traumatic brain injury who undergo a craniotomy: analysis of a surgical series].

Introduction: In our setting, the ageing of the population has led to management of traumatic brain injury (TBI) in the later stages of life becoming an increasingly frequent problem.

Aim: To evaluate the association between age and the functional and survival prognosis of patients who have undergone surgery due to TBI.

Patients And Methods: We performed a retrospective analysis of a series of 404 patients submitted to surgery between the years 2000 and 2015: 144 youngsters (12-44 years), 77 adults (45-64 years), 148 geriatric patients (65-79 years) and 26 'super geriatric' patients (> 80 years).

Anterior sacral meningocele presenting as intracystic bleeding.

Purpose: To report a case of anterior sacral meningocele with intralesional bleeding secondary to sacrococcygeal trauma. Likewise, there is a discussion about the physiopathology and the surgical approach to these types of lesions.

Methods: A 43-year-old man diagnosed with Marfan syndrome suffered sacrococcygeal trauma.

Fluorescence guided resection with 5-aminolevulinic acid of a pilomyxoid astrocytoma of the third ventricle.

Fluorescence-guided resection with 5-aminolevulinic acid has been shown to be useful in the resection of certain brain tumors other than high grade gliomas, facilitating the intraoperative differentiation of neoplastic tissue. The technique enables the surgeon to ensure that no tumor fragments remain, thereby achieving higher rates of complete resection. Tihan first described pilomyxoid astrocytomas in 1999.
