We report the first case of a young patient who presented with the features of Horner's syndrome following a spinal extradural hematoma resulting from a ruptured arterio-venous malformation (AVM). Since there were features of early compressive myelopathy as well, urgent magnetic resonance imaging (MRI) scan of the spine revealed features suggestive of an extradural hematoma in the cervico-thoracic junction. The patient underwent an emergent laminectomy with an evacuation of the hematoma. The histological features were consistent with that of an AVM...

Arterio-Venous Malformations (AVMs) are high flow vascular anomalies, commonly seen in head, neck and extremities. AVMs represent a direct connection between the arterial and the venous systems. They are congenital, often asymptomatic and rarely manifest before adolescence. Depending on the site, size and symptoms, treatment options varies from conservative management to surgical resection. Here, we report a case of 20-year-old male patient with long standing lump in the anterior abdominal wall with no typical clinical features of vascular lesions...

Pulmonary arterio-venous malformations (PAVMs) are abnormal pulmonary arteries and pulmonary veins communicating directly without interposition of a capillary bed and about 80-90% of patients with PAVMs eventually may present with hereditary hemorrhagic telangiectasia (HHT), remaining ones are sporadic cases. On the other hand, about 15-35% of HHT patients may present with PAVMs. The PAVMs have a tendency to grow and increase in size over time and various factors like puberty, pregnancy and pulmonary arterial hypertension (PAH) affect growth...

We report the case of a 56-year-old woman who underwent total resection of a Masson's tumor or intravascular papillary endothelial hyperplasia (IPEH), which was discovered due to a left temporal intracerebral hematoma revealed by aphasia. IPEH is more often localized on cutaneous and subcutaneous locations, intracranial IPEH are rare and only approximately twenty cases have been published to date. These tumors are a benign vascular lesion composed of papillary intravascular proliferation of epithelial cellular associated thrombosis with fibrin deposits responsible for vascular lumen obliteration...

BACKGROUND: Stereotactic radiosurgery (SRS) is a well-established treatment modality for cerebral arterio-venous malformations (AVMs). The main limiting factor in the radiosurgical treatment of AVMs is the volume of the nidus with high-grade lesions often requiring combined treatment to reduce the SRS target volume. To overcome this limitation, we have been using a combined treatment approach consisting of endovascular embolization with ONYX followed by SRS. OBJECTIVE: To evaluate our clinical experience for safety and feasibility of this multimodality treatment approach...

PURPOSE: Complete obliteration of treated arteriovenous malformations (AVMs) can be diagnosed only by confirming the disappearance of arterio-venous (A-V) shunts with invasive catheter angiography. The authors evaluated whether non-invasive arterial spin labeling (ASL) magnetic resonance (MR) imaging can be used to diagnose the obliteration of AVMs facilitate the diagnosis of AVM obliteration after treatment with stereotactic radiosurgery (SRS). MATERIAL AND METHODS: Seven patients with a cerebral AVM treated by SRS were followed up with ASL images taken with a 3T-MR unit, and received digital subtraction angiography (DSA) after the AVM had disappeared on ASL images...

BACKGROUND: Most arteriovenous malformations (AVMs) are localized and occur sporadically. However, they also can be multifocal in autosomal-dominant disorders, such as hereditary hemorrhagic telangiectasia and capillary malformation (CM)-AVM. Previously, we identified RASA1 mutations in 50% of patients with CM-AVM. Herein we studied non-RASA1 patients to further elucidate the pathogenicity of CMs and AVMs. METHODS: We conducted a genome-wide linkage study on a CM-AVM family...

In 1995 a 16-year old girl was diagnosed with a large left thalamic AVM that was considered unsuitable for microsurgical resection and was treated with radiotherapy twice, which led to angiographic cure. She re-presented 19 years after initial treatment with a symptomatic acute thalamic haemorrhage. Her digital subtraction angiography was negative for arterio-venous shunting. MRI/MRA showed cystic change with adjacent contrast enhancement in the region of the previously irradiated arteriovenous malformation...

We report a case of a young girl who was admitted with history of sudden onset left hemiplegia, when she was 5 years old. Investigations revealed no vascular malformation or abnormality. On conservative treatment, she progressively improved and had residual hemiparesis. She continued to have intermittent episodes of generalized and focal convulsions. For persistent convulsions, she was investigated again with MRI and angiography after 5 years of first presentation. Investigations at this time revealed a large arteriovenous malformation in the left posterior frontal region...

Peripheral arterio-venous malformations (pAVMs) are congenital vascular anomalies that require treatment, due to their severe clinical consequences. The complexity of lesions often leads to misdiagnosis and ill-planned treatments. To improve disease management, we developed a computational model to quantify the hemodynamic effects of key angioarchitectural features of pAVMs. Hemodynamic results were used to predict the transport of contrast agent (CA), which allowed us to compare our findings to digital subtraction angiography (DSA) recordings of patients...

A 6-year-old boy from Comilla, was admitted in Dhaka Medical College Hospital with exertional dyspnea, central cyanosis, clubbing and was finally diagnosed as pulmonary Arterio-Venous Malformation (PAVM) by bubble contrast echocardiography, and pulmonary CT angiography. As PAVM is rare in children, it is often not thought of in differential diagnoses and the diagnosis remains in disguise. In this report, we described the clinical presentation of 6-year-old child with PAVM and also how to investigate the case to get the diagnosis...

INTRODUCTION: Neurological disorders in pregnancy can be pregnancy related or can be caused by exacerbation of a pre-existing neurological condition or sometimes may even be detected for the first time during pregnancy in which it might be an incidental finding. The diagnosis and management of the neurological disorders in pregnancy is always a challenging task due to varied symptomatology and risks to the fetus. The evaluation and management should be performed in a stepwise fashion and requires multidisciplinary approach...

OBJECTIVE: Endovascular aortic aneurysm repair has become the principle technique used to treat abdominal aortic aneurysms. However, its long-term success is limited by complications, including type II endoleaks from lumbar arteries and the inferior mesenteric artery. Treatment of these endoleaks can be difficult. The most commonly performed procedure is embolisation via mesenteric or iliolumbar vessels. Embolic agents currently used include coils, glue and Onyx, all of which have their limitations...

A temporal lobe abscess was diagnosed in a 57-year-old man. A urethral catheter had been inserted 12 days earlier, just prior to clot evacuation of a subacute haematoma secondary to an arterio-venous malformation. Fever persisted despite debridement and treatment with meropenem and vancomycin. Gram stains of operative samples showed no bacteria. Extended cultures grew pinpoint colonies after 5 days. Meanwhile, sequencing of bacterial 16S rDNA from operative specimens had identified Mycoplasma hominis; the bacterial colonies were subsequently similarly identified...

BACKGROUND & AIMS: Hereditary haemorrhagic telangiectasia is characterized by arterio-venous malformations (AVM). It frequently involves the liver without clinical symptoms, but may lead to biliary ischaemia, portal hypertension, or fatal high-output heart failure. The indication of liver transplantation is controversial. METHODS: Herein, we report the case of a 65-year-old female patient with a 'double Osler syndrome' consisting of hereditary haemorrhagic telangiectasia (HHT) and type I hereditary angioedema diagnosed at the age of 25 and 22 years respectively...
