Various diseases that impact different systems and organs in the body may trigger manic episodes. Strokes are often associated with psychiatric symptoms, particularly depressive and, more rarely, manic. We herein report a case of bipolar disorder secondary to cerebrovascular disease in a 67-year-old man with no personal or family history of psychiatric illness who, at the age of 64, had a bilateral ischemic stroke in the middle cerebral artery territory. About 20 days after this stroke, he experienced a manic episode. Three years later, he experienced a second manic episode, with another hospitalization in a psychiatric ward. With this case, we intend to emphasize that, although rare, the diagnosis of mania after stroke should not be forgotten, and most important, one should be aware of the recurrence of affective episodes just as in non-medical-caused bipolar disorder.
Posterior reversible encephalopathy syndrome (PRES) is a rare disease attributed to an increase in blood pressure that exceeds the autoregulatory capabilities of the cerebral vasculature, resulting in brain edema. Although PRES primarily affects adults, the pediatric population is also at risk. Radiologists must be aware of that risk because the imaging features on brain MRI are often atypical, especially in pediatric patients. Over a 6-year period, nine pediatric patients were diagnosed with PRES at our institution. Here, those patients are evaluated retrospectively regarding demographic characteristics, clinical profiles, imaging aspects, and outcomes. In this pictorial essay, we review the typical and atypical imaging findings of PRES in pediatric patients, demonstrating that it should be considered in patients with a clinical profile suggestive of the diagnosis, given that prompt, effective treatment is important for full recovery, thus avoiding major morbidity and mortality in such patients.
Desmoid tumours are rare locally aggressive mesenchymal tumours with a high local recurrence rate, particularly in the head and neck locations. We present the case of a 5-year-old child with a locally invasive inoperable desmoid tumour of the masticator space who underwent a low-dose chemotherapy regimen for 17 months, obtaining a long-term complete response. Definitive evidenced-based treatment guidelines are lacking. Therefore, paediatric patients should be managed by specialised multidisciplinary teams to try to achieve the best tumour control while minimising treatment associated morbidity and mortality. Available treatment options include surgery, radiotherapy and different systemic medical therapies. Whereas traditionally, surgery was the mainstay of treatment, more conservative options have increasingly shown adequate tumour control with little associated morbidity. In this decision making it is mandatory to take into account the patient’s age, tumour location and extension, and potential short-term and long-term treatment-related sequelae to minimise functional and cosmetic compromise.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
