RESUMO
Paroxysmal sympathetic hyperactivity (PSH) is a relatively common syndrome typically observed following traumatic brain injury (TBI). It manifests through a combination of non-specific symptoms that collectively define its presentation. Linked to sympathetic hyperactivity, takotsubo syndrome is a cardiomyopathy marked by left ventricular dysfunction and may coincide with PSH. While various factors can lead to the simultaneous occurrence of these syndromes, a notably rare scenario involves their manifestation after brain tumor removal. The nonspecific nature of PSH symptoms and of the cardiac dysfunction in takotsubo syndrome pose challenges in accurately diagnosing these conditions in an intensive care unit (ICU) setting. They often overlap with more prevalent diagnoses like sepsis, pulmonary embolism, and acute heart failure. Thus, it is crucial for clinicians dealing with these patients to be aware that symptoms indicating sympathetic activity surge and left heart failure might prompt consideration of takotsubo syndrome and PSH. This study presents the case of an 8-year-old girl who developed takotsubo syndrome associated with sympathetic hyperactivity following the surgical removal of a bulbar tumor. To the best of our knowledge, this is the tenth case of PSH following brain tumor removal in a pediatric patient and the first reported case of occurrence of takotsubo linked to PSH after brain tumor removal. We offer a detailed account of the patient's clinical journey in the ICU, accompanied by a comprehensive review of relevant literature to identify similar cases. The significance of this case study lies in emphasizing the potential occurrence of takotsubo syndrome due to PSH and underscores the importance of early diagnosis and management due to their association with unfavorable clinical outcomes.
