Tumor de Pott y absceso cerebral secundario a sinusitis aguda de foco dentario en paciente pediátrico / Pott's tumor and cerebral abscess secondary to acute sinusitis of dental focus in a pediatric patient

El tumor de Pott es una entidad rara, definida como un absceso subperióstico asociado a osteomielitis del hueso frontal. Suele presentarse como complicación de sinusitis aguda o crónica del seno frontal, y se describe con mayor incidencia en población pediátrica, siendo una complicación grave por su alta morbimortalidad. Se presenta a un paciente pediátrico con tumor de Pott y absceso cerebral posterior a una sinusitis aguda de foco odontogénico, en la que los pilares de tratamiento son drenaje quirúrgico precoz y antibioticoterapia prolongada. Se describe la clínica, manejo médico-quirúrgico y seguimiento posterior, ya que, en ausencia de antecedentes, se debe buscar dirigida- mente enfermedad periodontal y realizar un estudio de inmunodeficiencia primaria.

Pott's tumor is a rare entity, defined as a subperiosteal abscess associated with osteomyelitis of the frontal bone. It usually presents as a complication of acute or chronic sinusitis of the frontal sinus and it is described with a higher incidence in the pediatric population, being a serious complication due to its high morbidity and mortality. We present a pediatric patient with Pott's tumor and brain abscess after acute sinusitis of odontogenic focus, in which the pillars of treatment are an early surgical drainage and prolonged antibiotic therapy. The clinic, medical-surgical management and subsequent follow-up are described, since in the absence of antecedents, periodontal disease should be sought directly and a study of primary immunodeficiency performed.

Empiema subdural recidivante secundário à sinusite bacteriana frontal em um adolescente imunocompetente: relato de caso / Relapsing subdural empyema secondary to frontal bacterial sinusitis in an immunocompetent adolescent: case report

A sinusite é uma causa rara de infecção intracraniana, sendo responsável por 2,4% dos casos em pacientes jovens, e tem como a complicação intracraniana mais frequente o empiema subdural (ESD). Descrevemos um caso raro de um adolescente imunocompetente de 16 anos que evoluiu com confusão mental, rebaixamento do nível de consciência, anisocoria, hemiparesia à direita, afasia e febre. Tomografa computadorizada confirmou ESD, e paciente foi submetido à avaliação laboratorial e abordagem clínico-cirúrgica para tratamento do quadro.

Sinusitis is a rare cause of intracranial infection, accounting for 2.4% of cases in young patients. The most frequent intracranial complication is subdural empyema (SDE). We describe a rare case of a 16-year-old immunocompetent adolescent who developed mental confusion, lowered consciousness, anisocoria, right hemiparesis, aphasia, and fever. Computed tomography confirmed SDE, and the patient underwent laboratory evaluation and clinical-surgical approach for treatment of the condition.

Isolated frontal sinusitis due to Pseudallescheria boydii.

We report a case of recurrent sino-nasal fungal infection due to Pseudallescheria boydii (P. boydii) in a 33-year-old diabetic woman. It is very essential to identify P. boydii, as Miconazole is the only antifungal drug of choice. However, histological examination of the specimen for clinching clues such as intercalary conidia and chlamydoconidia plays an important role in identifying P. boydii, when fungal culture fails to yield the growth. On follow-up, the woman responded for the treatment with Miconazole and is free of symptoms, with no recurrence after 6 months.
