Review Case ReportsContralateral acute subdural hematoma following traumatic acute subdural hematoma evacuation.
Contralateral acute subdural hematoma (ASDH) occurring after removal of traumatic ASDH is a rare, but nearly devastating postoperative complication. We treated a 26-year-old male who developed a contralateral ASDH shortly after craniectomy for evacuation of a traumatic ASDH. ⋯ Literature review suggests that the old are more susceptible to contralateral ASDH following evacuation of traumatic ASDH. Contralateral ASDH following evacuation of traumatic ASDH is a rare but potentially lethal complication, so neurosurgeons should try to detect such contralateral hematoma formation and prevent clinical deterioration.

Case ReportsCharacteristics of intraoperative abnormal hemodynamics during resection of an intra-fourth ventricular tumor located on the dorsal medulla oblongata.
Abnormal hemodynamics during extirpation of a para-medulla oblongata (MO) tumor is common and may be associated with direct vagal stimulation of the medullary circuit. However, resection of tumors on the dorsal MO may also induce hemodynamic instability without direct vagal stimulus. The objective of this study was to examine the characteristics of hemodynamic instability unrelated to vagal stimulus during dissection of an intra-fourth ventricular tumor with attachment to the dorsal MO. ⋯ The preoperative volume of the MO in these patients was 1.11 cc less than that in patients with normal hemodynamics, but the volume after tumor resection was similar in the two groups (5.23 cc and 5.12 cc). This suggests that the MO was compressed by the conglutinate tumor bulk, with resultant fluctuation of hemodynamics. Recognition of and preparation for this phenomenon are important for surgery on a tumor located on the dorsal MO.

Case ReportsStereotactic biopsy and drainage of a brainstem abscess caused by Listeria monocytogenes.
Listerial rhombencephalitis and brain abscesses are rare, but potentially life-threatening conditions. Early initiation of antibiotic therapy is crucial, but establishing the diagnosis of listerial brainstem abscess can be difficult. Stereotactic biopsy and drainage of space-occupying abscesses of the brainstem should be considered especially in cases of rapid clinical deterioration. We successfully performed stereotactic biopsy and drainage of a listerial brainstem abscess in a 42-year-old male patient who deteriorated despite antibiotic treatment, demonstrating that this approach is suitable in such patients.

Endovascular coiling as the first treatment strategy for ruptured pericallosal artery aneurysms: results, complications, and follow up.
We apply endovascular coiling as the first treatment option for ruptured pericallosal artery aneurysms. We conducted a retrospective analysis of the clinical and radiological outcomes of this treatment strategy and morphological factors associated with the success of endovascular coiling, to assess the safety and feasibility of our management strategy. From January 2003 to January 2012, we attempted endovascular coiling as the first-intention treatment for 30 consecutive patients with ruptured pericallosal artery aneurysms including those with intracerebral hematoma. ⋯ One patient had a major aneurysm recurrence that was uneventfully reembolized. Sixteen of our 30 patients had good outcomes (modified Rankin scale [mRS] 0-2), 7 had moderate disability (mRS 3), and 4 had severe disability (mRS 4-5) at 3 months after treatment. The management strategy for coiling as the first-intention treatment for ruptured pericallosal artery aneurysms has the potential to become an acceptable alternative to surgical clipping for selected cases, although a larger study population and longer follow-up periods are needed before definitive conclusions can be drawn.

Case ReportsSpinal dural arteriovenous fistula with lipomyelodysplasia.
A 72-year-old man presented with a very rare case of spinal dural arteriovenous fistula (AVF) with lipomyelodysplasia manifesting as progressive paraparesis and bladder dysfunction. Magnetic resonance imaging revealed a spinal lipoma associated with tethered cord and spinal cord swelling with dilated perimedullary veins. Embolization of the spinal dural AVF was successfully performed, and is an optional treatment for coexisting spinal dural AVF and lipomyelocele in adults.
