Introduction

Intracranial bleeding into the PUTAMEN, a BASAL GANGLIA nucleus. This is associated with HYPERTENSION and lipohyalinosis of small blood vessels in the putamen. Clinical manifestations vary with the size of hemorrhage, but include HEMIPARESIS; HEADACHE; and alterations of consciousness.

Delayed Diagnosis of Temporomandibular Joint Dislocation in Severe Stroke Patients

Article

Author: Tanaka, Tatsuya ; Honda, Eiichiro ; Matsuno, Akira ; Momozaki, Nobuaki

A 79-year-old woman with a history of left cerebral infarction developed altered consciousness and left hemiplegia. CT of the head revealed a putaminal hemorrhage. She underwent tracheal intubation followed by a tracheostomy for long-term airway management. Despite improved consciousness, the patient continued to experience dysphagia and was fed via a nasal tube. Subsequent axial CT and 3D CT scans revealed an empty glenoid fossa in both temporomandibular joints (TMJs) with the condyles positioned anteriorly, consistent with chronic bilateral anterior TMJ dislocation. After an unsuccessful attempt at manual reduction, closed manual reduction was successfully performed under general anesthesia with muscle relaxants, allowing the patient to resume oral feeding. This case underscores the importance of considering TMJ dislocation in stroke patients with persistent dysphagia. Early diagnosis and timely intervention are crucial for improving patient outcomes in such cases.

Abstract Background The development of minimally invasive endoscopic neurosurgery has enabled widespread application of endoscopic surgery via the ipsilateral transfrontal approach for putaminal hematoma evacuation. However, this approach is unsuitable for putaminal hematomas that extend into the temporal lobe. We adopted the endoscopic trans-middle temporal gyrus approach, instead of the conventional surgical approach, for the management of these complicated cases and determined its safety and feasibility. Methods Twenty patients with putaminal hemorrhage underwent surgical treatment at the Shinshu University Hospital between January 2016 and May 2021. Of these, two patients with left putaminal hemorrhage that extended into the temporal lobe underwent surgical treatment using the endoscopic trans-middle temporal gyrus approach. The procedure entailed the use of a thinner transparent sheath to reduce the technique's invasiveness, a navigation system to determine the location of the middle temporal gyrus and the sheath's trajectory, and an endoscope with a 4K camera for higher image quality and utility. The sylvian fissure was compressed superiorly using our novel “port retraction technique” (i.e., by tilting the transparent sheath superiorly) to avoid damage to the middle cerebral artery and Wernicke's area. Results The endoscopic trans-middle temporal gyrus approach allowed sufficient hematoma evacuation and hemostasis under endoscopic observation without any surgical complexities or complications. The postoperative course was uneventful in both patients. Conclusion The endoscopic trans-middle temporal gyrus approach for putaminal hematoma evacuation helps avoid damage to normal brain tissue, which could result from the wide range of motion of the conventional technique, particularly when the hemorrhage extends to the temporal lobe.

Intracerebral hemorrhage in methanol toxicity patients during COVID-19 pandemic: case report and review of literature

Review

Author: Savaie, Mohsen ; Babadi, Armin Jahangiri ; Ajudani, Reza ; Safari, Hosein ; Alizadeh, Pooyan

PURPOSEThe aim of this study is to examine the clinical and imaging manifestations of methanol toxicity during the COVID-19 pandemic, as well as to review existing studies on this topic. The most common cause of methanol intoxication is methanol-adulterated liquor. The primary metabolite of methanol, formic acid, is responsible for pathological changes. Symptoms typically present within 6-24 h of consumption and can include visual disturbances, acute neurological symptoms, and gastrointestinal issues. During the initial year of the COVID-19 pandemic, methanol poisoning cases increased significantly.METHODSIn this study, We present six different patients with methanol intoxication and their clinical and imaging features.RESULTSIn the literature review, the most common clinical presentation was loss of consciousness and obtundation and the other was vision loss. CT scan findings showed bilateral putaminal necrosis and hemorrhage in 55% of methanol toxicity patients.CONCLUSIONMethanol intoxication, causing bilateral putaminal involvement and a 50% mortality rate in intracerebral hemorrhage patients, warrants urgent toxicological analysis due to potential putaminal hemorrhage.
