Diabetes insipidus (DI) is a recognized transient or permanent complication following transsphenoidal surgery (TSS) for pituitary tumors. ⋯ Although transient DI is a relatively common complication of endoscopic and microscopic TSS, permanent DI is much less frequent. The underlying pathology is an important predictor of both occurrence and permanency of postoperative DI.

Meningioma growth rates are highly variable, even within benign subgroups, with some remaining stable, whereas others grow rapidly. ⋯ The proposed models might enable more accurate prediction of time to meningioma recurrence and thus determine optimal postoperative management. Moreover, combining this model with current knowledge of molecular processes underpinning recurrence could permit the identification of distinct meningioma subtypes and enable better-targeted therapies.

Tribute to Milton D. Heifetz (1921-2015): The Man Behind the Heifetz Aneurysm Clip.
Milton Dave Heifetz (1921-2013) was a pioneer American neurosurgeon who spent the majority of his career at Cedars-Sinai Hospital in California. Heifetz greatly influenced the field of neurosurgery as an innovator, leader, and academic neurosurgeon. His redesign of the aneurysm clip addressed the long-standing issue of a fatiguing spring. ⋯ In 1975, he published The Right to Die: A Neurosurgeon Speaks of Death With Candor, a book which played a major role in our modern-day advanced directives. Throughout his life, Heifetz was an inspirational individual who consistently worked towards solutions to surgical and ethical problems. We present a historical vignette on his life, career, and contributions to neurosurgery.

Falcine meningiomas have unique characteristics including their high rates of recurrence, association with high grade pathology, increased male prevalence, and potential for diffuse involvement of the falx. ⋯ The recurrence of falcine meningiomas is related to the diffuse presence of tumor between the leaflets of the falx. Increased extent of resection including, when possible, a clear margin of falx surrounding the tumor base was associated with the best long-term outcomes in our series, particularly for recurrent tumors.
