Tree Stand-Related Injuries in Nonadmitted and Admitted Patients at a Level 2 Trauma Center in Michigan: 2015-2019.

Introduction: Tree stand-related injuries (TSRI) are more common than firearm-related injuries in hunters. Most previous studies on the topic used trauma databases that only include admitted patients. This study characterizes injury patterns found in nonadmitted and admitted TSRI patients presenting to a level 2 Michigan trauma center.

Acute Oculomotor Nerve Palsy Caused by Compression from an Aberrant Posterior Communicating Artery.

Oculomotor nerve palsy (ONP) is a rare neurological deficit associated with numerous underlying pathologies. Of these, aneurysm of the posterior communicating artery (PCOM) has been described due to the intimate association with the third cranial nerve in the basal cistern. Less described are other vascular abnormalities and their contribution to ONP.

Preoperative Embolization in Tandem with Surgical Resection for Cerebral Arteriovenous Malformations.

A number of treatment options are available for cerebral arteriovenous malformations (AVMs) including surgical resection, stereotactic radiosurgery, and endovascular embolization. Endovascular embolization may be used pre-operatively to reduce the size of large AVMs and thus reduce surgical complications. Here we present two patients who successfully underwent preoperative embolization of their AVMs and subsequent surgery.

Intracranial germinoma.

Pineal region tumors make up less than 1% of all intracranial neoplasms, with the majority being of germ cell origin. We describe the diagnostic evaluation and treatment of a patient presenting with neurological deficits who was found to have a germinoma of the pineal gland.

A pictorial review of complications of acute coalescent mastoiditis.

This case study highlights the extracranial and intracranial manifestations of severe otomastoiditis. A 35-year-old man presented with numerous symptoms, including ear and neck pain, headache, temporary vision loss, fever, malaise, and nausea and vomiting. Imaging studies led to the diagnosis of coalescent mastoiditis with septic dural sinus thrombosis, venous hemorrhagic infarctions, brain abscesses, and subdural empyema.

Delayed resolution of Chiari I-associated hydromyelia after posterior fossa decompression: case report and review of the literature.

Objective And Importance: The expected time interval for resolution of hydromyelia after Chiari I decompression is lacking in the literature. This case report highlights one instance of delayed resolution of Chiari-induced hydromyelia.

Clinical Presentation: We report an adolescent girl with a Chiari I malformation and hydromyelia.

In utero spontaneous cervical thoracic epidural hematoma imitating spinal cord birth injury.

A neonate male born cesarian due to a breech presentation was noted to have no spontaneous movements of the limbs after delivery. Radiographs were not demonstrative of pathology. However, MRI revealed a large intraspinal mass with significant distortion of the cervicothoracic spinal cord.

Eyebrow incision with supraorbital trephination for endoscopic corpus callosotomy: a feasibility study.

Objective: We describe a novel technique for the partial bisection of the corpus callosum in order to increase the minimally invasiveness of this procedure.

Methods: Brow incisions with midline trephinations were performed in six adult cadavers. An endoscope was next introduced and used to transect approximately the anterior two-thirds of the corpus callosum.

Duane's syndrome and giant parietal foramina.

We report a 14-month-old male with Duane's syndrome and bilateral parietal calvarial defects. This child had no other known medical conditions. The Duane's syndrome involved the left eye.
