A Rare third ventricle solitary tuberculoma

The localization of the tuberculoma at the third ventricle is rare. The authors report a case of third ventricle solitary Tuberculoma which has occurred in a 10 year old patient and revealed by a syndrome of intracranial hypertension without tuberculosis stigma. This lesion appears clinically and radiologically as a primary brain tumor. A total removal using a subchoroidal approach to the third ventricle has been performed. Histological examination showed a tuberculous like granuloma. An adjuvant antituberculous chemotherapy  practiced for 6 months brought the complete cure. The authors insist on the diagnostic and therapeutic difficulties in front of a third ventricle solitary  tuberculoma

A case of congenital obstruction of magendie’s foramen: embryologic analysis and treatment

Abstract Background Fourth ventricle isolated Magendie’s foramen primitive obstruction is rare. The etiology and the pathophysiology of the constitution of this obstruction in congenital cases remain elusive. We report a case of congenital obstruction of Magendie’s foramen in an adult patient and discuss the embryogenic mechanism and our management of this rare pathology. Case presentation A 20 years old female patient without any medical history was referred for headaches and vomiting. Emergency CT scan revealed major hydrocephalus subsequently she underwent a ventriculoperitoneal shunt as initial treatment. The diagnosis of fourth ventricle obstruction was made 5 months later when the patient came back complaining of headaches, cerebellar signs and cystic dilatation of the fourth ventricle on CT scan and MRI. Fourth ventricle Magendie’s foraminoplasty via classic posterior fossa surgery brings complete cure. Conclusion Magendie’s foramen obstruction is rare. The embryological development of the posterior fossa and its content could explain the primitive obstruction which can be managed by classic surgery in case of unavaibility of endoscopy
