Papillary tumor of the pineal region: Is stereotactic radiosurgery efficient for this rare entity?

BACKGROUND: Papillary tumors of the pineal region are rare neuroepithelial lesions that were described for the 1st time in the WHO 2007 classification. Management of such lesions remains controversial. CASE DESCRIPTION: We describe the case of a 26-year-old female who presented with intracranial hypertension syndrome secondary to a 1.9 cm3 lesion of the pineal region causing hydrocephalus. The patient benefited from an endoscopic third ventriculocisternostomy and a biopsy of her lesion in favor of a papillary tumor of the pineal region. After discussion of the surgical risks, the patient refused the surgical option and a stereotactic radiosurgery (SRS) was performed. She improved both clinically (allowing her to regain autonomy) and radiologically (reduction of 60% of tumor volume) at 1 year follow-up. CONCLUSION: Because of the rarity of the lesion, literature is yet not able to find consensus concerning management of such lesion, but SRS has proven efficiency for these Grades II or III lesions with high recurrence rates. Therefore, it should be considered as a primary therapeutic option allowing good outcome with low risks for the patient.

History of African women in neurosurgery.

The number of women in the medical field has increased in Africa over the last few decades, yet the underrepresentation of women within neurosurgery has been a recurrent theme. Of all surgical disciplines, neurosurgery is among the least equitable, and the rate of increase in female surgeons lags behind other surgical disciplines such as general surgery. This historical review provides an overview of the history of women in neurosurgery and their current status on the African continent. To the authors' knowledge, this is the first article to provide such an overview.

Persistence of a trigeminal artery associated with a posterior meningeal artery aneurysm: case report and literature review.

A 59-year-old female presented with severe headache and trouble of consciousness. The CT showed a subarachnoid hemorrhage FISHER IV with a hematoma of the right cerebellum. The angiography discovered a persistent left trigeminal artery associated with an aneurysm of the right posterior meningeal artery. The attempt of embolization failed and the patient suffered cerebral vasospasm and died. The persistence of a trigeminal artery is found in 0.1-0.6% of the population. It is the most frequent embryological carotid-vertebral anastomosis. It appears at the fifth week of development and disappears when the embryo reaches 5-7 mm. This embryological persistence is associated with numerous vascular abnormalities. The literature review showed the presence of those aneurysms in the trigeminal artery itself or the communicating artery. The association that we described is the first to our knowledge. Therefore, this association is particular and interesting to expose.
