A case of an unfortunate tooth fairy visit to a ventilator-dependent child.

Pediatr Pulmonol 2022 06 8;57(6):1555-1556. Epub 2022 Apr 8.

Pediatric Pulmonology Unit, Dana-Dwek Children's Hospital, Tel-Aviv Sourasky Medical Center, Tel Aviv, Israel, affiliated to the Sackler Faculty of Medicine, Tel Aviv University, Tel Aviv, Israel.

An 8-year-old boy recently sustained a cerebellar arteriovenous malformation rupture, and subsequently suffered from severe neurological injury and became ventilator-dependent through a tracheostomy. During a routine clinic visit, the parents reported that a loose baby tooth had fallen out and disappeared 7 days earlier. The physical examination was unremarkable, but a chest X-ray demonstrated a foreign body in the left lung and secondary atelectasis. Read More

Pulmonary Arteriovenous Malformation and Its Vascular Mimickers.

Korean J Radiol 2022 02 4;23(2):202-217. Epub 2022 Jan 4.

Department of Radiology, Samsung Medical Center, Sungkyunkwan University School of Medicine, Seoul, Korea.

Pulmonary arteriovenous malformation (AVM) is a congenital vascular disease in which interventional radiologists can play both diagnostic and therapeutic roles in patient management. The diagnosis of pulmonary AVM is simple and can usually be made based on CT images. Endovascular treatment, that is, selective embolization of the pulmonary artery feeding the nidus of the pulmonary AVM, and/or selectively either the nidus or draining vein, has become a first-line treatment with advances in interventional devices.

Congenital pulmonary varix: Two case reports.

Medicine (Baltimore) 2021 Dec;100(51):e28340

Department of Radiology, Kansai Medical University, 2-5-1 Shinmachi, Hirakata, Osaka, Japan.

Rationale: Patients with congenital pulmonary varix are asymptomatic and require no treatment, but the radiological characteristics of a pulmonary varix are similar to those of a pulmonary arteriovenous malformation, which requires treatment. Pulmonary angiography is useful for obtaining information about the dynamics of pulmonary blood flow to differentiate a pulmonary varix from a pulmonary arteriovenous malformation for the purpose of treatment planning. Two cases of congenital pulmonary varices that were differentiated from pulmonary arteriovenous malformations based on pulmonary angiography findings are presented. Read More

Neurology 2022 02 8;98(7):292-295. Epub 2021 Dec 8.

From the Department of Clinical Neurosciences (J.I.R., A.K.);Department of Pediatrics (K.W., A.K., M.J.E.), Cumming School of Medicine, University of Calgary; Alberta Children's Hospital Research Institute (A.K., M.J.E.), University of Calgary; Hotchkiss Brain Institute (A.K., M.J.E.), University of Calgary, Alberta, Canada.

Hereditary hemorrhagic telangiectasia (HHT) is an autosomal dominant condition that is linked to a myriad of neurologic complications arising from vascular malformations of the brain, spinal cord, and lungs. Our case describes a previously healthy 3-year-old male who presented to hospital with fever of unknown origin and was found to have a brain abscess stemming from a pulmonary arteriovenous malformation (PAVM). This etiology was identified after a period of diagnostic delay; the medical team was suspicious for a proximal embolic source due to the presence of multiple tiny infarcts seen on MRI of the brain, but transthoracic echocardiogram and head and neck angiogram were unremarkable.

Young stroke due to pulmonary arteriovenous malformation.

BMJ Case Rep 2021 Jun 21;14(6). Epub 2021 Jun 21.

Neurology, University Hospital Southampton NHS Foundation Trust, Southampton, UK.

Young patients presenting with cryptogenic stroke should be investigated for cardiac and extra-cardiac sources of emboli. We present a patient who was investigated for a cardiac source of emboli, following multiple ischaemic strokes and migraine with aura over a period of 17 years. The events were initially thought to be related to a patent foramen ovale (PFO) on bubble contrast echocardiography, however, due to an unusual flow pattern to the left heart, she underwent a CT angiogram to exclude intrapulmonary shunting.

Placental Site Trophoblastic Tumor in a Pulmonary Vascular Malformation With Spontaneous Pneumothorax.

Ann Thorac Surg 2022 03 25;113(3):e211-e214. Epub 2021 May 25.

Department of Thoracic Surgery, Mazumdar Shaw Medical Centre, Narayana Health City, Bengaluru, Karnataka, India. Electronic address:

Placental site trophoblastic tumor, a rare variety of gestational trophoblastic disease, is traditionally limited to the uterus, found within the placental implantation site where it can lead to arteriovenous malformations. Gestational trophoblastic diseases are known to metastasize to the lungs, of which choriocarcinomas are the most common. However arteriovenous malformations related to such metastatic lesions are extremely rare. Read More
