ABSTRACT

SUMMARY Hemorrhagic pseudocysts with pseudoaneurysms are a rare and fatal complication of chronic pancreatitis due to the erosion of pancreatic to peripancreatic arteries. The timing of the rupture cannot be accurately predicted, but prompt diagnosis and management are essential to prevent further bleeding. We describe the case of a 68-year-old man who presented acute epigastric pain and anemia and had a history of chronic pancreatitis with a pseudocyst. A biliary and pancreas MRI showed an enlarged size of a known pancreatic pseudocyst with internal high signal intensity material. Color-Doppler ultrasonography showed pulsating signals in the pseudocyst, and our final diagnosis was a pseudoaneurysm in the pancreatic hemorrhagic pseudocyst. The pseudoaneurysm was successfully treated with coil embolization of the feeding artery. We report this case of a rare complication of chronic pancreatitis to show that color-Doppler ultrasound is a non-invasive and effective diagnostic tool for pseudoaneurysm, which enables early detection and prompt treatment without the need for invasive diagnostic modalities.

ABSTRACT

ABSTRACT Differentiating glaucomatous from nonglaucomatous optic disc cupping remains challenging. We present a case of a 48-year-old woman with an internal carotid aneurysm of approximately 3.5 mm × 6.5 mm that mimicked normal-tension glaucoma. The patient had a 2-year history of low vision acuity in her left eye and frontal oppressive headache. Owing to the carotid aneurysm, she developed an asymmetric vertical cup-to-disc ratio above 0.2, and marked inferotemporal neuronal rim loss and pallor of the residual rim were noted in the left disc. She also developed a visual field defect with an arcuate scotoma in the left eye. The patient was referred to a neurosurgeon and underwent endovascular aneurysm occlusion. This case highlights the diagnostic importance of recognizing that many neurological defects remain underdiagnosed.


RESUMO diferenciação de escavações glaucomatosas e não glaucomatosas ainda permanece um desafio ainda nos dias de hoje. Nos descrevemos um caso de aneurisma de carótida interna medindo 3.5mm x 6.5mm que simulava um glaucoma de pressão normal. O caso é sobre uma paciente feminino de 48 anos com história de 2 anos de baixa acuidade visual no olho esquerdo e cefaléia frontal. Devido ao aneurisma de carótida a paciente desenvolveu uma assimetria de escavação vertical maior que 0.2 no olho esquerdo em relação ao direito com defeito localizado da camada de fibras nervosas temporal inferior. Ela também apresentava um defeito arqueado temporal superior a esquerda, cruzando a linha média vertical consistente. Após o diagnostico confirmado pela ressonância magnética funcional, a paciente foi enviada para o neurocirurgião para realização de uma oclusão endovascular do aneurisma. Esse caso nos alerta da importância de se lembrar que não apenas o glaucoma gera escavações suspeitas no disco óptico e que ainda muitos defeitos por causas neurológicas são subdiagnosticados.

ABSTRACT

ABSTRACT Giant splenic artery aneurysm is a rare condition that represents an eminent life threatening for the patient, requiring, therefore, urgent surgical correction. A 61-year-old woman, former smoker, hypertensive, hypercholesterolemic and multipara sought our service because of a large tumor in the mesogastrium, which was an abdominal ultrasound finding. Despite the size of the tumor, the patient was asymptomatic. The angiotomography and the magnetic resonance image of the abdomen were suggestive of giant splenic artery aneurysm with more than 10cm in diameter that was confirmed by an angiography. She underwent surgery, open splenectomy, and partial aneurysmectomy. The approach of the celiac artery, which was ligated, was only possible with medialvisceral rotation because there was no possibility to view it through the anterior access. The histopathological test of aneurysmatic wall revealed atheroma plaques in the intima. The patient progressed without complications and she was discharged cured. In general, giant splenic artery aneurysms are symptomatic, however, as in the case we report, it may be asymptomatic and found in abdominal imaging exam. Although less invasive Interventional methods exist, such as laparoscopy and endovascular techniques, they were considered inappropriate in this case. Conventional open surgery should be the therapy of choice for a giant splenic artery aneurysm.


RESUMO O aneurisma gigante da artéria esplênica constitui condição rara, que representa risco de vida iminente para o paciente, necessitando, consequentemente, de correção cirúrgica urgente. Mulher de 61 anos, ex-fumante, hipertensa, com hipercolesterolêmica e multípara nos procurou por apresentar grande tumor no mesogástrio, achado de ultrassonografia abdominal. Apesar das dimensões do tumor, era assintomática. Angiotomografia e ressonância magnética de abdômen sugeriam tratar-se de aneurisma gigante de artéria esplênica com mais de 10cm de diâmetro, confirmado por angiografia. Foi submetida a tratamento cirúrgico aberto, tendo sido realizadas esplenectomia e aneurismectomia parcial. A abordagem do tronco celíaco, que foi ligado, só foi possível com rotação visceral medial, pois não havia possibilidade de visualizá-lo pela via anterior. O exame anatomopatológico da parede do saco aneurismático revelou placas de ateroma na íntima. A paciente evoluiu sem intercorrências e teve alta hospitalar curada. Aneurismas da artéria esplênica de dimensões avantajadas, em geral, são sintomáticos, porém, como no caso em questão, podem ser assintomáticos e descobertos em exame de imagem do abdômen. Apesar de existirem métodos intervencionistas menos invasivos, como laparoscopia e técnicas endovasculares, eles não foram considerados adequados neste caso. Diante de um aneurisma gigante de artéria esplênica, a conduta terapêutica de eleição é a cirurgia convencional aberta.
