Osler-Weber-Rendu Disease Presenting as Recurrent Portosystemic Encephalopathy in a 75-year-old Female Patient / 대한소화기학회지

Osler-Weber-Rendu disease is a rare autosomal dominant disorder of fibrovascular tissues, characterized by a classic triad of mucocutaneous telangiectasias, recurrent hemorrhages, and a familial occurrence. Portosystemic encephalopathy in a patient with Osler-Weber-Rendu disease is rare, but we experienced a case presenting with recurrent portosystemic encephalopathy in Osler-Weber-Rendu disease. We report on a case of a 75-year-old female presenting with an altered mentality. Initial studies including brain imaging study did not reveal any specific cause for her mental status. She was diagnosed with the rare disease after a series of tests and received conservative treatment. Her neurological status recovered fully without complication after conservative treatment and she was discharged after 18 hospital days. This case demonstrated an extremely rare case of Osler-Weber-Rendu disease presenting as portosystemic encephalopathy treated successfully with conservative treatment. For patients who have shown hepatic encephalopathy without a definite cause, we recommend evaluation for the possibility of Osler-Weber-Rendu disease. Conservative treatment based on treatment of advanced liver cirrhosis could be an alternative solution.

Blue Rubber Bleb Nevus Syndrome as a rare cause of iron deficiency anemia: a case report and review of literature

Blue Rubber Bleb Nevus Syndrome is a rare disorder that is characterized by multiple recurrent vascular malformations of skin and gastrointestinal tract. The affected patients may present with diverse manifestations including iron deficiency anemia. We report this syndrome in a 22-year-old man that was referred to our hospital for iron deficiency anemia with unknown cause and vascular malformations in the skin and gastrointestinal tract. Because of stable hemoglobin level, we decided to treatment him by iron supplementation and close follow up. We report this case along with a review of literature

The Return of an Old Worm: Cerebral Paragonimiasis Presenting with Intracerebral Hemorrhage

Paragonimiasis is caused by ingesting crustaceans, which are the intermediate hosts of Paragonimus. The involvement of the brain was a common presentation in Korea decades ago, but it becomes much less frequent in domestic medical practices. We observed a rare case of cerebral paragonimiasis manifesting with intracerebral hemorrhage. A 10-yr-old girl presented with sudden-onset dysarthria, right facial palsy and clumsiness of the right hand. Brain imaging showed acute intracerebral hemorrhage in the left frontal area. An occult vascular malformation or small arteriovenous malformation compressed by the hematoma was initially suspected. The lesion progressed for over 2 months until a delayed surgery was undertaken. Pathologic examination was consistent with cerebral paragonimiasis. After chemotherapy with praziquantel, the patient was monitored without neurological deficits or seizure attacks for 6 months. This case alerts practicing clinicians to the domestic transmission of a forgotten parasitic disease due to environmental changes.

Achados de imagem e alternativas terapêuticas das malformações vasculares periféricas / Imaging findings and therapeutic alternatives for peripheral vascular malformations

As malformações vasculares periféricas compreendem um espectro de lesões que se tornam aparentes no decorrer da vida e podem ser encontradas em praticamente todo o corpo. São pouco comuns e frequentemente confundidas com o hemangioma infantil. Estas doenças são completamente distintas tanto em relação à história clínica como ao prognóstico e às formas de tratamento. Nestas lesões, a história evolutiva e as características do exame físico são de extrema importância para o adequado diagnóstico clinicorradiológico, que guiará a melhor alternativa terapêutica. As classificações mais recentes dividem as malformações vasculares periféricas levando em consideração o fluxo sanguíneo (alto e baixo) e os componentes vasculares envolvidos (arteriais, capilares, linfáticos e venosos). As malformações vasculares periféricas representam um desafio diagnóstico e terapêutico, e exames complementares como tomografia computadorizada, ultrassonografia com Doppler e ressonância magnética, em conjunto com a história clínica, podem trazer informações quanto às características de fluxo e à extensão das lesões. Arteriografia e flebografia confirmam o diagnóstico, avaliam a sua extensão e orientam a decisão terapêutica. Malformações de baixo fluxo geralmente são tratadas por abordagem percutânea e injeção de agente esclerosante, enquanto para as malformações de alto fluxo o acesso é endovascular com uso de agentes embolizantes permanentes líquidos ou sólidos.

Peripheral vascular malformations represent a spectrum of lesions that appear through the lifetime and can be found in the whole body. Such lesions are uncommon and are frequently confounded with infantile hemangioma, a common benign neoplastic lesion. In the presence of such lesions, the correlation between the clinical and radiological findings is extremely important to achieve a correct diagnosis, which will guide the best therapeutic approach. The most recent classifications for peripheral vascular malformations are based on the blood flow (low or high) and on the main vascular components (arterial, capillary, lymphatic or venous). Peripheral vascular malformations represent a diagnostic and therapeutic challenge, and complementary methods such as computed tomography, Doppler ultrasonography and magnetic resonance imaging, in association with clinical findings can provide information regarding blood flow characteristics and lesions extent. Arteriography and venography confirm the diagnosis, evaluate the lesions extent and guide the therapeutic decision making. Generally, low flow vascular malformations are percutaneously treated with sclerosing agents injection, while in high flow lesions the approach is endovascular, with permanent liquid or solid embolization agents.

Malformaciones Vasculares / Vascular malformation

Las malformaciones vasculares son anomalías presentes siempre desde el nacimiento que, al contrario de los hemangiomas, nunca desaparecen; pueden crecer durante toda la vida por hipertrofia. Según la clasificación de la ISSVA, las malformaciones vasculares se dividen en función del vaso afectado en capilares o venulares, venosas, linfáticas, arterio-venosas y combinadas o complejas. Cada una de ellas, con unas peculiaridades clínicas y hemodinámicas definitorias.

Vascular malformations are anomalies always present at birth that, contrary to hemangiomas, never regress; and may hypertrophy during lifetime. According to the ISSVA classification, vascular malformations are divided, depending on the affected vessel, into capillary or venular, venous, lymphatic, arteriovenous and combined or complex; each with certain defining clinical and haemodynamic peculiarities.
