PURPOSE: To investigate pulmonary venous anomaly as a cause of pulmonary arteriovenous malformation (PAVM) misdiagnosis. MATERIALS AND METHODS: We reviewed adult patients within a 7.5-year period with CT scans initially diagnosed with PAVM and subsequent conventional pulmonary angiograms. RESULTS: Pulmonary arteriography showed no PAVM on arterial phase for 10 out of 99 patients, comprising the misdiagnosed group. Four misdiagnosed patients had pulmonary venous anomalies and six had nodular lesions on CT...

Tracheobronchopathia osteochondroplastica (TPO) is a rare pathology characterized by a progressive segmentary stenosis of the respiratory tract due to proliferation of osteocartilagineous nodules in the lumen of the distal part of the trachea and large bronchial trunks. Prognosis is usually benign, but some cases with an acute progression and a lethal outcome have been described. Clinical presentation is non specific, the chest x-ray is generally normal and there are not typical radiological signs of suspicion: diagnosis of TPO is usually incidental...

Renal artery aneurysms (RAAs) are an uncommon finding but are more often associated with other congenital disorders. The complex (hilar) RAAs constitute a subset of RAAs that present a therapeutic dilemma for the vascular surgeon; because of their anatomic location. This dilemma worsens when hilar RAAs occur with a solitary kidney where organ preservation is vital. Ex-vivo reconstruction with autotransplantation is especially suitable for hilar RAAs, even when they are associated with a solitary kidney. We report two of such cases of RAA's with a solitary kidney in patients with pertinent congenital anomalies...

Posterior fossa houses very vital and sensitive structures namely midbrain, pons, medulla, and cerebellum. These structures are irrigated by vertebral, posterior inferior cerebellar, anterior inferior cerebellar, and superior cerebellar arteries. Parts of brain located in posterior fossa control important parts of body so any variation pertaining to stenosis, atresia, hypoplasia, fenestration, agenesis, and duplication in the arteries supplying these parts alter the irrigation pattern culminating into various morbid and mortal neurologic disorders...

A 4-year-old girl who had been treated for asthma since the age of 2 years had a severe coughing fit and died suddenly. The patient had a history of occasional severe coughing fits, and these fits had been worsening in severity during the week before her death. Prior to death, she was taken to a clinician, and thymic hypertrophy was suspected based on chest X-ray findings. The clinician recommended that she visit a general hospital at a later date; however, she died that night. Postmortem radiology and autopsy revealed a large mass in the anterior mediastinum compressing the heart and airway, and no other findings attributable to sudden death were observed...

The knowledge of both normal and abnormal anatomy of the veins of the neck may be important for surgeons performing neck surgery, to avoid inadvertent injury to vascular structures. In a 75-year-old man candidated to carotid endarterectomy preoperative CT-scan showed a rare anomaly of the venous drainage in the area of the anterior jugular vein (AJV), that usually begins in the suprahyoid region via the confluence of several superficial veins, to open into the ipsilateral external jugular vein. A large left sided venous trunk, originating from an anomalous proximal confluence with the internal jugular vein, descended in the AJV anatomical position, to cross over the sternum draining into the right subclavian vein...

BACKGROUND: Laparoscopic cholecystectomy (LC) has many advantages as compared to open cholecystectomy. However, vasculobiliary injuries still continue to be a matter of concern despite advances in laparoscopic techniques. Misidentification and misperception of vasculobiliary structures is considered to be a pivotal factor leading to injuries. Although many studies since time immemorial have stressed on the importance of anatomy, an insight into laparoscopic anatomy is what essentially constitutes the need of the hour...

Neonatal monitoring and other explorations required just after neonatal arterial ischemic stroke (NAIS) diagnosis remain elusive. This review attempts to propose guidelines on this topic. During neonatal period, three major contexts related to NAIS emerge: 1) Metabolic disorders including hypoglycemia; 2) Early post-natal infections; 3) Cardio-vascular anomalies. Different patient profiles have been defined (typical, atypical and at risk profiles). According to these profiles, a final decisional tree including biological monitoring and complementary explorations has been suggested to caregivers...

Infantile hemangioma is a benign vascular neoplasm that spontaneously involutes over time. Management, when needed, consists of medications, laser treatment and surgical excision. We describe a 3-year-old girl who presented shortly after birth with diffuse cutaneous hemangiomas, hepatosplenomegaly with liver lesions, anemia, and acute heart failure. She was diagnosed with hepatic and cutaneous infantile hemangioma based on skin biopsy. She developed progressive pulmonary hypertension with numerous pulmonary nodules suspicious for pulmonary arteriovenous malformations...

Pompe disease is an autosomal recessive disorder in which deficiency of the lysosomal enzyme acid alpha-glucosidase results in the accumulation of glycogen mostly in muscle tissues. Several reports suggest a higher incidence of intracranial vascular abnormalities (IVAs) in this condition, as well as brain microbleeds and cerebral vasculopathy. The aim of our study was to evaluate through neuroimaging studies the incidence of these anomalies in our cohort of late-onset Pompe disease (LOPD) patients asymptomatic for cerebrovascular disease, looking for correlations with clinical and genetic data...

Body stalk anomaly is a rare and severe malformation syndrome in which the exact pathophysiology and trigger factors are still unknown. Possible causes of body stalk anomaly include early amnion rupture with direct mechanical pressure and amniotic bands, vascular disruption of the early embryo, or an abnormality in the germinal disk. We present a case of body stalk anomaly diagnosed during antenatal sonographic evaluation at the first visit with the review of literature regarding this phenomenon. Sonographic features of the fetus included a severe midline defect of the fetal abdominal wall with a large extra-abdominal mass containing bowel and liver inside...

Double aortic arch (DAA) is a rare congenital anomaly associated with the formation of a vascular ring. Patients with DAA commonly suffer from complications caused by intracardiac and extracardiac malformations and different degrees of airway stenosis. Multislice computed tomographic angiography (MSCTA) is an intuitive and effective medical imaging technique in clinical diagnosis of DAA. MSCTA can accurately manifest the aortic arch and the course of the descending aorta and airway stenosis in three-dimension (3D)...

Apela (also known as Elabela, Ende, and Toddler) is a small signaling peptide that activates the G-protein-coupled receptor Aplnr to stimulate cell migration during zebrafish gastrulation. Here, using CRISPR/Cas9 to generate a null, reporter-expressing allele, we study the role of Apela in the developing mouse embryo. We found that loss of Apela results in low-penetrance cardiovascular defects that manifest after the onset of circulation. Three-dimensional micro-computed tomography revealed a higher penetrance of vascular remodeling defects, from which some mutants recover, and identified extraembryonic anomalies as the earliest morphological distinction in Apela mutant embryos...

INTRODUCTION: Mandibular reconstruction performed after virtual planning has become more common during recent years. The gold standard for extensive mandibular reconstruction is of course a fibular free flap. In designing an osteomyocutaneous fibula flap, poor planning, aberrant anatomy and/or inadequate perforator vessels are the most frequent causes of complications and may force the surgeon to modify the flap design, explore the contralateral leg or harvest an additional microvascular flap...

Annually, carpal tunnel release is one of the most commonly executed orthopaedic procedures. Despite the frequency of the procedure, complications may occur as a result of anatomic variations. Understanding both normal and variant anatomy, including anomalies in neural, vascular, tendinous, and muscular structures about the carpal tunnel, is fundamental to achieving both safe and efficacious surgery. Reviewing and aggregating this information reveals certain principles that may lead to the safest possible surgical approach...

Bronchopulmonary dysplasia (BPD) is a form of chronic lung disease in premature infants following respiratory distress at birth. With increasing survival of extremely low birth weight infants, alveolar simplification is the defining lung characteristic of infants with BPD, and along with pulmonary hypertension, increasingly contributes to both respiratory morbidity and mortality in these infants. Growth restricted infants, infants born to mothers with oligohydramnios or following prolonged preterm rupture of membranes are at particular risk for early onset pulmonary hypertension...
