Review Case Reports
Spontaneous tumor regression of intracranial solitary fibrous tumor originating from the medulla oblongata: A case report and literature review.
Intracranial solitary fibrous tumor (SFT) is a rare occurrence and involvement of the fourth ventricle rarely reported. Because of its rarity, some characteristics of intracranial SFT seem to still remain uncertain. ⋯ Although the location of the SFT in the fourth ventricle is rare, SFT should be considered as 1 of the differential diagnosis of fourth ventricle tumors. In addition, this case indicates that SFT in the fourth ventricle may regress on occasion spontaneously without a precisely known cause for this spontaneous partial regression.

Orbito-Temporal Bone Cyst of Metastatic Breast Cancer: Case Report and Literature Review.
Metastatic breast cancer in the bone rarely has a cystic appearance, and while it is common in the orbit, its metastasis to the orbitotemporal skull is rare. Consequently, it is difficult to diagnose it. We report and discuss a rare case of metastatic breast cancer with simple cyst appearance in the orbitotemporal region of the skull. ⋯ Metastatic breast cancer should be considered in the differential diagnosis even if it appears as a simple cyst in the orbitotemporal bone after long-term remission.

Pituitary apoplexy is associated with visual, cranial nerve, and endocrine dysfunction. In this article, the results of surgical and conservative management of pituitary apoplexy in a single center are evaluated and a review of the literature is presented. ⋯ A tailored approach to pituitary apoplexy, one that does not include an absolute need for surgery, is appropriate. Conservative management is appropriate in selected patients presenting without visual deficits.

Review Case Reports
Surgical Obliteration of Anterior Cranial Fossa Dural Arteriovenous Fistulas via Unilateral High Frontal Craniotomy.
Surgical obliteration is generally recommended for anterior cranial fossa dural arteriovenous fistulas (ACF DAVFs) because of a high risk of bleeding and the difficulty of endovascular approaches. Surgical obliteration is generally performed via a frontobasal craniotomy; however, it is slightly excessive over the target fistula. Here, we present 2 cases of ACF DAVFs treated with small craniotomy without frontal sinus involvement and a review of the related literature. ⋯ Constructing a small corridor and a deep working distance in unilateral small high frontal craniotomy may be a slightly unusual approach; however, it is thought to provide sufficient space and a range of microscopic views that facilitate surgical manipulation without requiring extensive bone work.

Lateral interbody fusion (LIF) is an effective adjuvant for circumferential minimally invasive surgery (CMIS) treatment of adult spinal deformity (ASD). Accessing L5-S1 via an oblique LIF (OLIF) approach (OLIF 5-1) allows for anterior LIF (ALIF) at the lumbosacral junction without repositioning the patient. We review the early outcomes and complications of OLIF 5-1 at the bottom of a long construct for an MIS approach to treat ASD. ⋯ A single-position MIS OLIF 5-1 at the bottom of a long construct in conjunction with multilevel pre-psoas LIF seems to be a safe and effective technique for improving SL, global LL, and SVA with a low risk of perioperative and postoperative complications.
