ABSTRACT

Mucoceles are cystic masses that generally affect the sinuses. It occurs as a result from obstruction of the ostium of a sinus and consequential accumulation of mucus. Frontal and ethmoid sinuses are mostly affected. Usually, the clinical symptoms are insidious, varying with the extent of the affected region. The treatment is surgical and endoscopic surgery is the method of choice in most cases. The present study is aimed at describing the main characteristics of paranasal sinuses mucoceles, demonstrating and illustrating a series of atypical presentations with emphasis on imaging findings.

ABSTRACT

Persistent stapedial artery is a rare congenital anomaly that occurs by a failure in the involution of such artery. Most patients with persistent stapedial artery are asymptomatic. The imaging diagnosis is made principally by means of multidetector computed tomography. In the present case, persistent stapedial artery was an incidental computed tomography finding. The authors discuss the embryogenesis, computed tomography findings and the importance of an early diagnosis of such anomaly.


A artéria estapedial persistente é uma rara anomalia congênita que ocorre por uma falha na sua involução. A maioria dos pacientes com artéria estapedial persistente é assintomática. O diagnóstico de imagem é feito principalmente pela tomografia computadorizada multidetectores. Neste estudo a artéria estapedial persistente foi um achado ocasional no exame tomográfico. São discutidos a embriologia, os achados tomográficos e a importância do seu diagnóstico precoce.

ABSTRACT

Paciente de 75 anos, feminina, com dor torácica há 20 dias. Foi submetida à propedêutica radiológica, seguida de toracotomia com excisão de tumor fibroso solitário da pleura, neoplasia rara e de sintomatologia inespecífica, o que dificulta seu diagnóstico etiológico.


A 75-year-old female patient with chest pain for 20 days. She was conducted to radiological workup, followed by thoracotomy with excision of solitary fibrous tumor of the pleura, a rare cancer and with nonspecific symptoms, which makes its etiological diagnosis difficult.

ABSTRACT

O diafragma pode ser lesado tanto nos traumas contusos quanto nos penetrantes. A incidência de lesão diafragmática nas feridas penetrantes na região tóraco-abdominal esquerda por arma branca varia de 20 a 24. A porcentagem de assintomáticos pode atingir 30 e a lesão, usualmente, é clinicamente despercebida. A maioria dos casos apresenta alterações radiológicas mínimas. A principal complicação é a hérnia estrangulada, que aumenta a taxa de mortalidade de 3 a 7 para 25 a 30 . O alto índice de suposição é o fator mais importante para o diagnóstico. O uso da videolaparoscopia diagnóstica e terapêutica, em casos selecionados, diminuiu o número de laparotomias brancas. A baixa sensibilidade diagnóstica associada à clínica e aos procedimentos radiológicos requer abordagem intervencionista para que as lesões diafragmáticas sejam rapidamente diagnosticadas e evitadas futuras complicações.


Diaphragmatic rupture occurs after blunt or penetrating wound. The incidence of diaphragmatic rupture in patients with penetrating wounds in the left thoracoabdominal area varies from 20 to 24. The rupture is observed in up to 30 of asymptomatic patients and is not usually detected by physical exam. In most cases, radiological investigation shows minimal alterations. The main complication is the strangulated hernia, which rises the mortality rate from 3-7 to 25-30 . A high grade of clinical suspicion is the main contributor to elucidate the diagnostic. The use of diagnostic and therapeutic videolaparoscopy has downsized the number of white laparotomies. Considering the low sensitivity of clinical exam and radiological investigation, an aggressive approach to diagnose diaphragmatic lesions and avoid future complications is recommended.

ABSTRACT

O pneumoencéfalo, o pneumoventrículo, e a fístula liquórica são complicações degrande morbidade decorrentes do traumatismo cranioencefálico(TCE) , que requeremadequada vigilância neurológica. Este relato apresenta uma vítima de TCE que evoluiucom pneumoencéfalo e pneumoventrículo hipertensivo, associados com fístula liquóricae meningites de repetição. Foi submetida aos tratamentos clínico e cirúrgico, commelhora neurológica.


Pneumocephalus, pneumoventricle and fistula are high morbidity complications caused by traumatic brain injury (TBI), requiring adequate neurological follow. We report a case of a victim of TBI that evolved with pneumocephalus and tension pneumoventricle associ-ated with fistula and repeated meningitis. Subjected to clinical and surgical treatments, the patient progressed favorably, with neurological improvement.
