Review Case Reports
Factors influencing the prognosis in intracranial dural arteriovenous fistulas with perimedullary drainage.
Intracranial dural arteriovenous fistulas with perimedullary venous drainage (IDAVFPD) are classified as type V dural arteriovenous fistulas. Publications are limited to single case reports and small case series. We conducted a systematic review of the literature for patients with IDAVFPD. The aim of this study is to identify the predictive factors of poor prognosis in patients with IDAVFPD. ⋯ The poor outcomes were correlated to the presence of brainstem signal abnormalities on magnetic resonance imaging, whereas the prognosis does not depend on age, sex, clinical presentation, or anatomic characteristics of the fistula.

We sought to (1) describe psychological, physical, and cognitive functions in patients 10 years after intracranial aneurysm rupture and (2) identify any differences in outcome variables between age groups, gender or aneurysm locations. ⋯ Ten years after aneurysm rupture the majority of patients seem to be well-functioning physically, whereas the psychological and cognitive functions are affected. A screening of the mental health of these patients in connection to radiological follow-up might be helpful to identify which patients need further referral to psychiatric treatment for anxiety and depression disorders.

Review Case Reports
Vertebral brown tumors causing neurologic compromise.
Brown tumors are nonneoplastic lesions that occur only in the setting of hyperparathyroidism. Although vertebral brown tumors are relatively rare pathologic entities, their incidence seems to be on the rise, as evidenced by multiple case reports published during the past four decades. An extensive review of these lesions is lacking in the literature. We present a case of paraparesis secondary to vertebral brown tumor followed by a detailed review of the literature. ⋯ In patients presenting with a lytic vertebral lesion and known hyperparathyroidism or end-stage renal disease, brown tumor should be considered in the differential diagnosis. In select cases with minimal neurologic symptoms, parathyroidectomy may be warranted prior to neurosurgical intervention.

Postcraniotomy infections have generally been treated by debridement of infected tissues, disposal of the bone flap, and delayed cranioplasty several months later to repair the resulting skull defect. Debridement followed by retention of the bone flap has also been advocated. Here we propose an alternative operative strategy for the treatment of postcraniotomy infections. ⋯ Surgical debridement, bone flap disposal, and immediate titanium mesh cranioplasty may be a suitable option for the treatment of postcraniotomy infections. This treatment strategy facilitates the eradication of infectious sources and obviates the risks and costs associated with a second surgical procedure.
