Background:
Papillary tumor of the pineal region (PTPR) is a rare neuroepithelial tumor with CentralNervous System (CNS) World Health Organization (WHO) grade II or III classification. Due to its rarity, there is no clear census on treatment. The purpose of this study is to identify the optimal treatment plan focused on extending overall survival (OS).
Methods:
This is an institutional case series with review of the literature. Fifty-three publicationswere analyzed. Only cases with histological diagnosis of PTPR were included. Data collected included demographics, treatment modalities, disease progression, and OS.
Results:
The analysis included 105 patients from the literature and 3 new cases (54 female,50%) with an average age of 33.1 years (range 1–73 years). The average lesion size was 26.4 mm (range 5–50 mm) in longest axis. All patients underwent an initial resection. There were 46 cases of surgery alone. The remaining cases received adjuvant therapy including radiation (RT), stereotactic radiosurgery (SRS), chemotherapy (CT), or RT and CT. The average follow-up was 61.4 months (range 1–240 months). OS at 1 year was 96.9%, at 5 years was 87.5%, and at 10 years was 80.2%. Overall progression-free survival (PFS) was 57.4%. Statistical significance was observed in PFS in the surgery plus SRS group and surgery plus CT and RT group. Surgery with SRS had the best PFS (75%), and OS at 1 year (100%) and 5 years (88.9%). Surgery with CT and RT had the best OS at 10 years (85.7%).
Conclusion
We describe a case series and literature review of PTPR to help guide the most effec-tive treatment strategies for this rare disease entity. We recommend surgery followed by SRS as the treatment of choice because of its best PFS and 5-year survival rates. We would also recommend adding chemotherapy in the event of disease progression or recurrence as adjuvant radiation and chemotherapy provided the best 10-year survival.

Vascular compression of neural tissue causing neurological symptoms is a wellknown phenomenon. This is commonly seen in trigeminal neuralgia and, less commonly, in hemifacial spasm by small arteries, which can be treated by microvascular decompression. Rarely, larger arteries, such as the vertebral arteries, may compress the brainstem. This can lead to symptoms of pontine or medullary distress like hemiparesis, dysphagia, or respiratory distress. This is treated by macrovascular decompression. Due to the rare and heterogenous nature of this disease, there is no standardized approach. We describe a novel technique whereby the vertebrobasilar system is mobilized anterolaterally towards the occipital condyle with a sling to decompress the brainstem.
We report two cases of vertebrobasilar dolichoectasia causing brainstem compression. A carotid patch graft sling with anterolateral mobilization to the occipital condyle is described as a surgical nuance to macrovascular decompressive surgery. Briefly, the vertebral artery was identified and dissected away from the brainstem and the bulbar cranial nerves. Bovine pericardium graft was used to create a sling around the artery by suturing the two ends together. The sling was then fixed either to the occipital condyle using cranial plating screws or suturing to the dura of the occipital condyle.
A novel surgical technique for management of vertebrobasilar dolichoectasia causing brainstem compression with progressive neurological deterioration is reported. Anatomical location and the offending vessel should guide neurosurgeons to select the best surgical option to achieve complete decompression of the involved neural structures.
