Transient lateral rectus palsy associated with acute coronary syndrome treated with percutaneous coronary intervention: a case report.

BACKGROUND: Patients who experience angina and acute myocardial infarction often receive diagnostic coronary angiography and percutaneous coronary intervention. CASE PRESENTATION: A 54-year-old Persian man with acute coronary syndrome was admitted to the hospital and underwent elective percutaneous coronary intervention. Two hours after the procedure, the patient experienced ophthalmoplegia and diplopia. The diagnosis was abducens nerve palsy resulting in transient lateral rectus palsy. The cause is presumed to have been an ischemic event affecting the unilateral abducens nerve. This could have occurred owing to the microembolism during the percutaneous coronary intervention, which resulted in left lateral rectus palsy. Within 1 month, the diplopia was relieved completely, and the physical examination was normal. CONCLUSION: The occurrence of neuro-ophthalmic complications that may arise from percutaneous coronary intervention is extremely rare. To our knowledge, this is the second reported case of unilateral rectus palsy associated with percutaneous coronary intervention.

Lateral rectus muscle palsy secondary to sphenoid sinusitis.

Isolated sphenoid sinus disease is a rare, often misdiagnosed condition of the paranasal sinus. If left untreated, it can lead to complications involving pituitary gland, cavernous sinus, neurological and vascular structures nearby. Early recognition and treatment are critical to prevent the progression of the disease. We present a case of a 60-year-old woman with a history of severe left-sided headache, facial pain, diplopia and left lateral rectus palsy. She was initially referred to ophthalmology and rheumatology for possible giant cell arteritis. Magnetic resonance imaging revealed opacification in left sphenoid sinus with cavernous sinus/superior orbital fissure involvement consistent with left sphenoid sinusitis. She was then referred to the ear, nose and throat department and had endoscopic transnasal sphenoidotomy in theatre. Culture results showed Haemophilus influenza and fungal pseudohyphae. She recovered three months later after a course of antibiotics and antifungals. The onset of isolated sphenoid sinus disease is often insidious and the diagnosis of this condition remains a challenge. Magnetic resonance imaging and computed tomography remain the best diagnostic tools to recognise and manage this condition.

Parálisis del nervio motor ocular externo luego de anestesia neuroaxial combinada epidural-espinal / Paralysis of the external oculomotor nerve after combined epidural-spinal neuroaxial anesthesia

Introducción: El abordaje del espacio subaracnoideo fue descrito por Quincke en el 1891. En la actualidad es práctica común para la realización de la anestesia neuroaxial subaracnoidea en las pacientes obstétricas. Las complicaciones descritas, asociadas a esto, son varias. Dentro de estas, la parálisis del nervio abducens o VI par no es frecuente y en ocasiones, no está relacionada a la punción ya que se produce días después del evento. Objetivo: Revisar la información relacionada con la complicación de parálisis del VI par. Presentación del caso: Paciente de 33 años de edad, femenina, de profesión médico, con antecedentes personales de migraña, historia de anestesia neuroaxial epidural sin complicaciones, que para la realización de una cesárea de segmento arciforme y salpinguectomia parcial bilateral, recibió una anestesia combinada peridural-espinal. El transoperatorio transcurre con estabilidad hemodinámica, hizo cefalea al tercer día del posoperatorio, que la atribuyó al antecedente de migraña y fue tratada sin evaluación por anestesiología con dipirona. A los 10 días de operada hace desviación de la mirada y diplopia, se diagnostica parálisis del VI par. Fue tratada por Neurología y se plantean varios diagnósticos diferenciales. Los estudios imagenológicos resultan negativos, se trató con vitaminas y se produjo remisión a las 6 semanas. Conclusiones: El diagnóstico de esta complicación es necesario ya que puede pasar inadvertida la relación con la anestesia y, por tanto, ser mal conducido su tratamiento(AU)

Introduction: The approach to the subarachnoid space was described by Quincke in 1891. It is now a common practice to perform subarachnoid neuroaxial anesthesia in obstetric patients. The complications described, associated with this, are several. Within these, the paralysis of the abducens nerve or sixth pair is not frequent and sometimes is not related to the puncture, since it occurs days after the event. Objective: To review the information related to the complication of paralysis of the sixth pair. Case presentation: A 33-year-old female patient, a physician, with a personal history of migraine, a history of epidural neuroaxial anesthesia without complications, who underwent combined epidural-spinal anesthesia for performing a cranial segment cesarean section and bilateral partial salpingectomy. The transoperative period runs with hemodynamic stability. There was headache three days after surgery, which was attributed to the migraine history and the patient was treated, without evaluation by anesthesiology, with dipyrone. At 10 days after surgery, the eyes are diverted and diplopia is manifested, paralysis of the sixth pair is diagnosed. She was treated by neurology and several differential diagnoses were proposed. Imaging studies are negative. She was treated with vitamins and remission occurred at six weeks. Conclusions: The diagnosis of this complication is necessary, since the relationship with anesthesia may go unnoticed and, therefore, its treatment may be poorly conducted(AU)

Sixth cranial nerve palsy caused by gastric adenocarcinoma metastasis to the clivus.

Tumors of the clivus and metastases to the clivus are very rare. Metastasis involving the clivus has previously been described in only two case reports. In skull metastasis, the breast and prostate are the most common primary foci, while metastasis from gastric carcinoma is extremely rare. A review of the English literature revealed only one published case of clivus metastases from gastric adenocarcinoma. There is no literature thoroughly explaining the differential diagnosis between chordoma and metastasis. Here we report a rare case of metastasis to the clivus from a gastric adenocarcinoma in a 42-year-old female patient with sudden blurry vision, presenting as bilateral cranial nerve VI palsy.

Glufosinate herbicide intoxication causing unconsciousness, convulsion, and 6th cranial nerve palsy.

Although glufosinate ammonium herbicides are considered safe when used properly, ingestion of the undiluted form can cause grave outcomes. Recently, we treated a 34-yr-old man who ingested glufosinate ammonium herbicide. In the course of treatment, the patient developed apnea, mental deterioration, and sixth cranial nerve palsy; he has since been discharged with full recovery after intensive care. This case report describes the clinical features of glufosinate intoxication with a focus on sixth cranial nerve palsy. Our observation suggests that neurologic manifestations after ingestion of a "low-grade toxicity herbicide" are variable and more complex than that was previously considered.

Isolated Sphenoid Sinusitis with Orbital and Intracranial Complication

Sphenoid sinus is adjacent to important intracranial structures, such as major intracranial vessels and some cranial nerves. However isolated sphenoid sinusitis is often misdiagnosed because presenting symptoms are initially subtle. Therefore, if the diagnosis of the isolated sphenoid sinusitis is delayed and complications occur, it will lead to disastrous results. We experienced a rare case in which a 51-year-old male patient developed both brain abscess and abuducens nerve palsy and report this case with a review of the case and related articles.
