Review Case Reports
A Case Report of Endoscopic Endonasal Removal of Large Calcified Pituitary Adenoma and Literature Review.
Large calcified intrasellar masses, called pituitary stones, have been reported as calcified pituitary adenomas in the literature. Although relatively rare, calcified pituitary adenomas appear in various formations. Thus, whether the lesion is removable-and, if so, which approach is appropriate-mainly depends on its formation and quality. ⋯ We report a rare case of a large pituitary stone that was successfully removed via an endoscopic endonasal approach. This could therefore be a feasible, effective technique for the removal of pituitary stones, although careful analysis of preoperative magnetic resonance imaging is required.

Review Case Reports
Meningiomas Originated at the Falcotentorial Region: Analysis of Topographic and Diagnostic Features Guiding an Optimal Surgical Planning.
Meningiomas arising at the pineal region are a rare entity and still represent a great neurosurgical challenge given their deep location and critical neuroanatomic relationships. The optimal surgical approach to treat these lesions is still under debate. Our objective is to review the topographic and diagnostic features of these lesions, which can help to guide an optimal surgical outcome. ⋯ Pineal region meningiomas represent very infrequent, challenging lesions, and their description in the literature is scarce. The systematic topographic classification of these tumors and evaluation of the neuroanatomic structures involved are crucial to guide a safe and optimal surgical approach and achieve satisfactory outcomes.

Review Case Reports
Solitary Primary CNS Lymphoma mimicking third ventricular colloid cyst- case report and review of the literature.
Primary central nervous system lymphoma is a rare malignant tumor of the central nervous system. It is associated with poor prognosis and accounts for 0.7%-0.9% of all lymphomas and only 0.3%-1.5% of intracranial tumors. Typically, these lesions are in the cerebral white matter near the corpus callosum, the central gray matter, the basal ganglia-thalamus-hypothalamic region, the posterior fossa and the periventricular region. Only 2 cases with pure third ventricular lymphoma have been reported in the literature. ⋯ Eleven months after surgery, the patient is fully consciousness and oriented, with no memory issues or neurologic deficit. She is back to her baseline activities. We are reporting this case for the rarity of the disease and the unusual location of it.

Review Case Reports
Non-traumatic myositis ossificans as an uncommon cause of scoliosis: a case report and discussion of literature.
A 5-year-old pediatric patient developed scoliosis associated with nontraumatic myositis ossificans in the lumbar region. Although there have been reports in literature of syndromes leading to widespread muscle ossifications resulting in shoulder deformities owing to impaired movement in the facet joints, to the best of our knowledge there has been no report of scoliosis associated with myositis ossificans. ⋯ Nontraumatic, paravertebral myositis ossificans at an early age is a very rare pathology. Therefore, it must be recognized that spine deformities such as scoliosis and kyphosis can develop in neglected cases of paravertebral myositis ossificans. In addition, there is a high risk of confusion with malignant pathologies, such as osteosarcoma, in this area. Removal of the mass eliminates both the pain of myositis ossificans and prevents the development of scoliosis.

Randomized Controlled Trial
Development of a Virtual Reality Preoperative Planning System for Postlateral Endoscopic Lumbar Discectomy Surgery and Its Clinical Application.
Percutaneous endoscopic lumbar discectomy is an effective way to treat lumbar disc herniation. Traditional preoperative planning based on a 2-dimensional method by magnetic resonance/computed tomography may cause inaccuracy of puncture during surgery. We used virtual reality to stimulate a surgery environment and measured relevant 3-dimensional data. We then explored its applicability for increasing puncture accuracy during actual surgeries. ⋯ A virtual reality planning system is an accurate preoperative planning method that can significantly improve the puncture accuracy of percutaneous endoscopic lumbar discectomy and reduce fluoroscopic and location times.
