METHODS: This is a case report of a patient that underwent fundus examen, brain Magnetic Resonance Imaging (MRI) and arteriography. Genetic testing was performed by next-generation-sequencing (NGS). RESULTS: A 35-year-old woman presented with right hemiplegia with right homonymous lateral hemianopia and homolateral complete sensory deficit...

Direct communication between dysmorphic arteries and veins without an interceding capillary segment is known as arteriovenous malformation (AVM). Its etiology is still unknown; however, it is commonly acknowledged that it could be related to trauma or is congenital in origin. Often, AVMs are found in the central nervous system or other sites such as under the skin or in the deep solid organs. They can be encountered as a solitary abnormality or associated with another pathology. If they are large enough, they can deprive the neighboring tissue of oxygen, eventually leading to tissue damage and compressing the surrounding organs, causing potentially more serious consequences...

A 43-year-old female patient with a brain abscess and a complicated clinical course was diagnosed with hereditary haemorrhagic telangiectasia (HHT) at the Martin Zeitz Centre for Rare Diseases in Hamburg, Germany. The brain abscess was caused by pulmonary arteriovenous malformations (AVM), a typical finding in HHT. Patients with cryptogenic brain abscess should be screened for pulmonary AVM and HHT. This case report illustrates the importance of patient history and interdisciplinary exchange in patients with a broad clinical spectrum as well as interdisciplinary treatment in the case of complications of rare diseases...

Hereditary hemorrhagic teleangiectasia (HHT), also known as Rendu-Osler-Weber syndrome, is the most common cause of hepatic vascular malformations in adults. Different vascular shunts (arteriovenous, arterioportal or portovenous) lead to different clinical manifestations. Even though no hepatic-related symptoms are reported in the majority of cases, the severity of liver disease could lead to refractory medical conditions, in some cases requiring liver transplantation. The aim of this manuscript is to provide an updated overview of the current evidence regarding the diagnosis and treatment of HHT liver involvement and liver-related complications...

Hereditary haemorrhagic telangiectasia, also known as Rendu-Osler-Weber disease, is an autosomal dominant disorder of the fibrovascular tissue common in Western countries. It is characterized by the classical triad of mucocutaneous telangiectasia, arteriovenous malformations with recurrent epistaxis. Here we report a rare case of Hereditary haemorrhagic telangiectasia in a 66-year-old Indian male who presented with a history of recurrent epistaxis of forty years duration. The nasal telangiectasias were ablated under narrow band imaging guidance...

BACKGROUND: Excruciating generalized abdominal pain with features suggestive of shock, at the end of the first or early second week after laparoscopic cholecystectomy (LC), is a frightening and formidable diagnostic predicament. This is because the early known complications like biliary leak or vascular injuries are unlikely diagnoses. Hemoperitoneum, is not usually considered, but instead more common occurrences like acute pancreatitis, choledocholithiasis, and sepsis are suspected. A delay in diagnosis and subsequent management of hemoperitoneum could have disastrous consequences...

This review aimed to provide an overview of pulmonary arteriovenous malformations, including the major clinical and radiological presentations, investigation, and treatment algorithm of the condition. The primary etiology of pulmonary arteriovenous malformations is hereditary hemorrhagic telangiectasia (HHT), also known as Rendu-Osler-Weber syndrome, with mutations in the ENG gene on chromosome 9 (HHT type 1) or in the ACVRL1/ALK1 complex (HHT type 2). Epistaxis should always be evaluated when repeated, when associated with anemia, and in some cases of hypoxemia...

OBJECTIVE: Osteomalacia is an uncommon, overlooked and debilitating metabolic bone disease with numerous aetiologies. Herein, we report an atypical cause of osteomalacia - intravenous iron therapy. METHODS: Description of a case report of hypophophatemic osteomalacia induced by ferric carboxymaltose infusions. RESULTS: A 70-year-old male with Rendu-Osler-Weber syndrome requiring repeated infusions of ferric carboxymaltosewas admitted for disabling lower limb pain associated with persistent hypophosphatemia (1...

Hereditary hemorrhagic telangiectasia, also known as Rendu-Osler - Weber disease, is a rare, autosomal dominant vascular disease, with prevalence of 1/5,000. The condition is characterized by muco-cutaneous telangiectasias, which are responsible for a hemorrhagic syndrome of variable severity, as well as arteriovenous malformations (AVMs) appearing in the lungs, the liver, and the nervous system. They can be the source of shunts, which may be associated with high morbidity (neurological ischemic stroke, brain abscess, high-output heart failure, biliary ischemia…)...

An 18-year-old male, previously diagnosed with hereditary hemorrhagic telangiectasia (HHT), presented to the outpatient department with a complaint of generalized seizures and fever for the past five days. He had a history of recurrent epistaxis, progressive shortness of breath, and cyanosis. Magnetic resonance imaging (MRI) of the brain revealed an abscess in the temporoparietal region. A computed angiogram of the pulmonary vasculature showed the presence of arteriovenous malformation (AVM). A four-weekly antibiotic regimen was initiated, which resulted in a profound improvement in symptoms...

The SARS-CoV-2 pandemic has led researchers worldwide to study the patterns of association of SARS-CoV-2 with different diseases, which have been a prime focus of medical literature. Osler-Weber-Rendu syndrome, also known as hereditary hemorrhagic telangiectasia (HHT), is a rare genetic disorder in which patients present with recurrent epistaxis, nostril manipulations, and multiple arteriovenous malformations (AVMs) along with telangiectasias involving internal organs and mucocutaneous areas. In addition, these AVMs are prone to bleeding or act as a nidus for thrombus formation, apart from other serious complications, such as chronic hypoxemia, anemia, pulmonary artery hypertension, heart failure, and cerebrovascular accidents...

RATIONALE: Hepatic arteriovenous malformations (HAVMs) are a rare disorder reported in association with hereditary hemorrhagic telangiectasia (HHT), known as Rendu-Osler-Weber syndrome. HAVMs are usually detected in adulthood. PATIENT CONCERNS: A 29-year-old pregnant woman underwent a routine prenatal examination at 37 weeks of pregnancy. DIAGNOSIS AND INTERVENTIONS: There were fetal liver anomalies detected by prenatal ultrasonography and were managed...

Hereditary hemorrhagic telangiectasia (HHT) also known as Osler-Weber-Rendu disease is a rare autosomal dominant, multi-organ disorder that leads to formation of abnormal vascular connections resulting in devastating and life-threatening complications. Due to its multisystem character, wide range of clinical manifestations and variable expressivity, HHT remains a diagnostic challenge and requires close cooperation of specialists from various medical fields. Interventional radiology plays a key role in the management of this disease, helping maintain the health of HHT patients and minimize the risk of fatal complications...

Hereditary hemorrhagic telangiectasia (HHT), also known as Osler-Weber-Rendu disease, is a rare disorder with a case prevalence as high as one in 5000, causing arteriovenous malformations in multiple organ systems. HHT is familial with autosomal dominant inheritance, with genetic testing allowing confirmation of the diagnosis in asymptomatic kindreds. Common clinical manifestations are epistaxis and intestinal lesions causing anemia and requiring transfusions. Pulmonary vascular malformations predispose to ischemic stroke and brain abscess and may cause dyspnea and cardiac failure...

Osler-Weber-Rendu syndrome is an uncommon vascular disorder inherited as an autosomal dominant trait with varying penetrance and expression. A multidisciplinary approach is used for a detailed diagnostic workup and management based on the patient's symptoms at presentation.

Hereditary Hemorrhagic Telangiectasia (HHT) or Rendu-Osler-Weber Syndrome (ROW) is an autosomal dominant vascular disease, with an estimated prevalence of 1:5000. Genes associated with HHT are ACVRL1 , ENG , SMAD4 , and GDF2 , all encoding for proteins involved in the TGFβ/BMPs signaling pathway. The clinical diagnosis of HHT is made according to the "Curaçao Criteria," based on the main features of the disease: recurrent and spontaneous epistaxis, muco-cutaneous telangiectases, arteriovenous malformations in the lungs, liver, and brain, and familiarity...

BACKGROUND: Osler-Weber-Rendu syndrome is characterized by mucocutaneous telangiectasia and arteriovenous malformations in organs. Anesthesia for patients with Osler-Weber-Rendu syndrome is challenging due to complications and physiological changes. CASE PRESENTATION: The case was a 49-year-old female with Osler-Weber-Rendu syndrome, multiple pulmonary arteriovenous malformations and pheochromocytoma who presented for femoral bone head fracture with metastatic adenocarcinoma...

BACKGROUND: Rendu-Osler-Weber disease (Osler disease) is a genetic disease with an autosomal dominant inheritance pattern. It is characterized by widespread telangiectasia in multiple organs. Liver involvement of FNH is relatively common, but liver cancer is very rare, and there are few reports on hepatectomy or postoperative complications. We report a very rare case in which hepatectomy was performed for a patient with Osler disease. CASE PRESENTATION: The patient was a 39-year-old man with Osler disease who had been previously diagnosed with multiple FNH and who had been followed for 8 years...

BACKGROUND: Hereditary hemorrhagic telangiectasia (HHT), also known as Rendu-Osler-Weber syndrome is a bleeding disorder that can affect all parts of the body including the eyes. Different ocular abnormalities have been described in relation to HHT, but the pathogenesis of retinal involvement is still unknown. A few cases have described chorioretinal abnormalities primarily occurring in elderly patients. In this study, we present a unique case of a young female with known HHT and a series of retinal fundus images including optical coherence tomography (OCT) and optical coherence tomography angiography (OCTA) with macular telangiectasia-like lesions...
