Incidental Finding of Anomalous Pulmonary Venous Return of the Left Upper Lobe, a Rare Anatomical Variation.

Partial anomalous pulmonary venous return (PAPVR) is a rare congenital abnormality in which 1 to 3 of the pulmonary veins connect to the right atrium rather than the left atrium. In this synthesis of the literature on PAPVR of the left upper lobe, we attempt to illustrate this clinical entity using a case detected incidentally on chest computed tomography, explain the anatomical aspects of this anomaly, and summarize the reported incidence and etiology of left-sided PAPVR. Lastly, differential diagnoses, clinical relevance, and management of left-sided PAPVR are presented.

Multimodality appearance of multiple endocrine neoplasia type 1: A case report.

Multiple endocrine neoplasia type 1 is a rare autosomal dominant disorder classically characterized by a predisposition to tumors of the parathyroid glands, anterior pituitary, and enteropancreatic endocrine cells. We present the clinical details of a patient with diarrhea, nephrolithiasis, erectile dysfunction, and new onset abdominal pain, as well as a discussion of the etiology, pathophysiology, and classical imaging findings of this condition.

Popliteal artery embolism of bullet after abdominal gunshot wound.

Bullet embolism to the peripheral arterial system is a rare phenomenon which frequently results in misdiagnosis due to lack of early symptoms. Embolisms can go to either arterial or venous systems with common sites of injury including the left ventricle, pulmonary vein, thoracic and abdominal aorta and peripheral arteries. Herein we present a case of a 19 year old patient with multiple gunshot wounds to the torso with a bullet embolism to the left popliteal artery necessitating embolectomy.

Acute mesenteric venous thrombosis with a vaginal contraceptive ring.

Mesenteric venous thrombosis is a rare cause of abdominal pain, which if left untreated may result in bowel infarction, peritonitis and death. The majority of patients with this illness have a recognizable, predisposing prothrombotic condition. Oral contraceptives have been identified as a predisposing factor for mesenteric venous thrombosis in reproductive-aged women.

Acoustic experience alters the aged auditory system.

Objectives: Presbyacusis, one of the most common ailments of the elderly, is often treated with hearing aids, which serve to reintroduce some or all of those sounds lost to peripheral hearing loss. However, little is known about the underlying changes to the ear and brain as a result of such experience with sound late in life. The present study attempts to model this process by rearing aged CBA mice in an augmented acoustic environment (AAE).
