Kinsbourne syndrome is a rare neurological paraneoplastic syndrome associated with neuroblastic tumors. There are very few literatures on its anesthetic management and interaction with anesthetic agents. The epileptogenic potential of certain anesthetic agents such as ketamine, etomidate, and meperidine might trigger opsoclonus and myoclonus and have an impact on the long-term neurological outcome. The objective of this case report is to discuss the safety of anesthetic agents and their relationship in a patient with Kinsbourne syndrome. We discuss our experience in the anesthetic management of a child with Kinsbourne syndrome with ganglioneuroblastoma in the thoracic paravertebral space.

Opsoclonus myoclonus syndrome (OMS) is a rare, neurological condition affecting 1 in 10 000 000 people annually. Opsoclonus, defined as involuntary rapid, multivectorial oscillations of the eyes, together with ataxia and myoclonus are usually present. OMS may be paraneoplastic: often associated with occult neuroblastoma in childhood and with breast carcinoma or small cell lung carcinoma in adults. Other aetiologies include viral or toxic agents. The pathogenesis is thought to be immune mediated. A 37-year-old woman with previous inflammatory cranial mononeuropathies was admitted for elective dilatation and curettage (D&C). Immediately after she complained of left-sided paraesthesia and later became disoriented, with incoherent speech, inability to obey commands, opsoclonus of the eyes and myoclonic jerks. Investigations including onconeuronal antibodies, cerebrospinal fluid analysis, and imaging were normal. She was treated with intravenous methylprednisolone with rapid improvement. Previous surgeries with anaesthesia were uncomplicated. The anaesthetic agents used for the D&C were fentanyl and propofol.

Opsoclonus myoclonus syndrome (OMS) is a rare neurological condition causing rapid jerking involuntary eye movements and myoclonus. The combination of opsoclonus and myoclonus have led to condition being coined the "dancing eyes, dancing feet syndrome". There are a wide variety of paraneoplastic and para-infectious aetiologies for OMS and therefore a detailed workup is needed as OMS symptoms can precede the commencement of symptoms from the underlying triggering disease process. In this case report, we present a case of sphenoid sinusitis in a pregnant lady. We detail her presentation, investigatory work-up and treatment. We also review the pathophysiological theories that can lead to OMS in the current literature.

Opsoclonus myoclonus syndrome (OMS) is an inflammatory neurological disorder, which is characterized by chaotic uncontrolled movements of the eyes and involuntary jerk-like movements of the body. Different modalities of treatment have been described in medical literature to treat OMS. Immunomodulatory treatment with either steroids or intravenous immunoglobulin has been considered. Our case was a 14-year-old boy who presented with fever, mild confusion, without any seizures or focal deficits. On examination, he had opsoclonus in his eyes and had cortical myoclonus in his hands and body. On evaluation, he had low platelets, normal metabolic workup, normal brain imaging, and cerebrospinal fluid showed lymphocytic pleocytosis. He was managed conservatively and had spontaneous improvement in opsoclonus myoclonus by 5th day of his illness and complete recovery in 2 weeks. Although dengue is primarily considered hematotropic virus, it can involve nervous system as well and manifest with OMS.
