We present a case of PAVM, which was picked up on a chest X-ray done in a patient with hemoptysis who presented to the emergency department (ED) of a Medical College Hospital in South India. [jacpjournal.org]

Case Report: We present a 50 year old woman who presented with acute onset left sided weakness. Her vitals including blood pressure were noted to be normal on presentation. CT head revealed a right parietal lobar ICH. [neurology.org]

Due to the rarity in presentation as well as infrequent reports, there are no specific guidelines to diagnose and manage them. [saudisurgj.org]

The first patient presented with episodes of left extremity weakness and numbness as well as chronic headaches. The second patient presented with spontaneous intracerebral hemorrhage. [jnis.bmj.com]

• Fever

  He was not on regular follow-up for RHD and refused any history of fever. [jacpjournal.org]

  She also complained of low grade fever, breathlessness, and fatigue. Examination revealed an emaciated, anemic, centrally cyanosed girl with weight and height below 5th percentile. Oxygen saturation was 84% and respiratory rate 24/min. [frontiersin.org]

  There was neither any history of trauma nor any associated features of pain or fever. Patient was of normal built for his age and sex, and systemic examination was unremarkable. [contempclindent.org]

• Constipation

  Depending on the location of a vascular malformation and the structures it affects, it can also cause constipation, pelvic pressure, or swelling in the limbs. [nyulangone.org]

• Thrombosis

  The obvious cause of the pain was the torsion and secondary ischemia and thrombosis of the abdominal polypoid neoplasm. The extirpation of the neoplasm and partial resection of the greater omentum was done. [pubs.sciepub.com]

  Secondary changes include atherosclerosis, focal thrombosis, secondary dystrophic calcification, organisation and mild inflammation [ 15 ]. [omicsonline.org]

  These vascular spaces showed evidence of thrombosis with patchy dystrophic calcification and well-developed phlebolith [Figure 3] d and f]. [contempclindent.org]

  They do not have any systemic associations but are prone to thrombosis and hyphema. On microscopic examination, they appear as dilated vascular channels and often have a central thrombus. [eyewiki.aao.org]

  In some cases, fresh or older calcified blood clots ( thrombosis ) may be detected. Ultrasound evaluation of arteriovenous malformations also shows evidence of shunting of blood between the affected artery and vein with turbulent blood flow. [dermnetnz.org]

What Is the Treatment for Arteriovenous Malformations? The treatment team typically consist of a neurologist, neuroradiologist, neuropsychologist, neurosurgeon and anesthesiologist; a careful evaluation is key to successful treatment. [luriechildrens.org]

Treatment and prognosis Treatment options include: trans-catheter coil embolization surgery (historically treated with surgery) Once successfully treated (embolotherapy, surgical resection), prognosis is generally good for an individual lesion. [radiopaedia.org]

Prognosis Iris AVMs carry very little risk for morbidity or mortality and thus confer an excellent prognosis. BSCS Section 2. Fundaments and Principles of Ophthalmology BSCS Section 4. [eyewiki.aao.org]

As to the etiology of the AVM in this instance, there was a concern prior to hysterectomy for an AVM. Given the eventual diagnosis of arteriovenous fistula, this idea was again examined. [gynecology-obstetrics.imedpub.com]

No common etiological factors for the disease were found, which makes it very difficult to understand how the two disease processes occurred together in our patient. [frontiersin.org]

Etiology of the hemorrhage was deemed to be cryptogenic. A month later she improved to modified Rankin Scale (mRS) of 0. Three months later, she presented again with left sided weakness. [neurology.org]

Etiology The etiology of vascular malformations of the spinal cord has not been clearly defined. Intradural parenchymal malformations arise in a younger patient population and are believed to be congenital. [emedicine.medscape.com]
