Mesenchymal hamartoma of the liver - a case report and literature review by Elsa Rosado et al.
Abstract: We report a case of a mesenchymal hamartoma of the liver in a two-year-old boy. He presented to the emergency room with abdominal distention and vomiting. Abdominal ultrasound and computed tomography were performed and revealed a large, intra-peritoneal lesion, with thick wall, multiple cysts of variable size and solid septa. The lesion was surgically resected. Pathological examination revealed a mesenchymal hamartoma of the liver. We are including a short literature review, highlighting the main features of mesenchymal hamartoma of the liver, and discussing its differential diagnosis.

Neurocandidiasis: a case report and consideration of the causes of restricted diffusion by David J. Lin et al.
Issue: 7(5) :: Pages: 1-5
Abstract: Diffusion weighted magnetic resonance imaging has risen to the forefront of imaging for acute stroke. However, the differential diagnosis of restricted diffusion is wide and includes ischemia, metabolic derangements, infections, and highly-cellular masses. We present a case of central nervous system (CNS) candidiasis presenting radiographically as bilateral punctate areas of restricted magnetic resonance (MR) diffusion in the basal ganglia. This case illustrates the value of carefully considering the causes of restricted diffusion in the brain, notably to be broader than acute stroke and to include invasive fungal infections.

Sarcoidosis Manifesting as a Pseudotumorous Renal Mass by cott Goldsmith et al.
Abstract: A 53 year-old African American woman with a three-year history of pulmonary sarcoidosis had a follow-up computed tomographic scan to evaluate the status of her disease and response to treatment. On the scan, an abnormal, hypodense mass on the left renal superior pole, which was not present on previous scans, was incidentally discovered. The initial concern was of carcinoma, despite her lack of any urinary symptoms. She underwent further evaluation with magnetic resonance, and the enhancement pattern and the shape of the mass were more suggestive of lymphoma or infarction than a carcinoma. A review of literature revealed sparse case reports demonstrating sarcoidosis presenting as infiltrative granulomatous masses resembling tumors with nonspecific imaging qualities. This diagnosis was entertained and then proven by biopsy. Pseudotumorous renal sarcoid should be in the differential of renal masses, especially in patients with a history of sarcoidosis, as it alters clinical management.

Post-operative Seroma Causing Spontaneous Nipple Discharge: Diagnosis by Galactography by Ivan E. Ramirez-Hernandez et al.
Abstract: Nipple discharge is a common breast complaint in women. Discharge in the post-operative patient for breast cancer is especially concerning, as these women are at higher risk for recurrent or new breast cancer. Galactography is a reliable method to evaluate nipple discharge, attempting to identify a mass that may cause the discharge within the duct of concern. We present two cases of women with spontaneous nipple discharge after lumpectomy for breast cancer. In both cases, evaluation with galactography demonstrated a post-operative seroma that communicated with a native breast duct, causing nipple discharge. This presentation of a post-operative seroma is important to recognize by breast surgeons and breast imagers. Galactography can play an important role in the work up of these patients, demonstrating etiology of the nipple discharge with greater confidence than other imaging modalities.

Anomalous Single Coronary Artery on Low Dose MDCT by Anurag Yadav et al.
Abstract: Coronary artery anomalies may involve the origin, course, and structure of epicardial coronary arteries and occur in less than 1% of the general population. Clinical presentation ranges from being completely asymptomatic to sudden death. Multi-detector computed tomography has come a long way in the diagnosis of coronary artery anomalies since the introduction of 4 rows of detectors in scanners, considering its non invasive nature and the benefits of 3D reconstruction. Defining the coronary anatomy helps in clinical decision making and timely intervention. Since repeated angiographies may be required, low dose CT is an excellent investigation for diagnosis and post interventional follow up rather than repeated invasive catheter angiographies or high dose CT examination. We report two cases of clinically significant single coronary artery anomalies; a case of single Right coronary artery and another case of single Left coronary artery (Anomaly of origin & course).
