Abstract: Benign simple breast cysts are commonly seen in female breasts and can present as palpable masses. They are distinctly uncommon, however, in the male breast. We report a case of simple benign cyst of the breast in a 58-year-old man newly diagnosed with mantel cell lymphoma. The cyst was first identified incidentally on a staging contrast-enhanced chest computed tomography. Further evaluation with mammography and ultrasound revealed a mass that would be typically characterized as a benign simple cyst, but was biopsied since cysts are not known to occur in male breasts. Pathology results from ultrasound-guided core needle biopsy revealed benign cyst and focal fibrosis which was concordant with the imaging findings. In this case report, we will briefly discuss breast cysts in men and their imaging features including mammography and ultrasound.

Abstract: Primary neoplasms of the petrous apex are rare and include eosinophilic granuloma, chondroma, chondrosarcoma, chordoma, and schwannoma. We report just the second published case of an intraosseous schwannoma of the petrous apex and are the first to describe the entity using magnetic resonance imaging. By studying the computed tomography and magnetic resonance imaging features of this rare tumor, it is possible to suggest the diagnosis preoperatively.

Abstract: A 23 year old Asian female presented with swelling of right knee joint for 5 years with history of exacerbations and remissions of symptoms. She was initially diagnosed as a case of suprapatellar bursitis based on clinical and X-ray findings. Further evaluation with higher imaging modalities was pathognomonic of lipoma arborescens. Patient underwent synovectomy and the diagnosis was confirmed histologically. We describe a histologically proven case of lipoma arborescens to highlight the imaging findings on X-ray, Ultrasound and Magnetic resonance imaging with arthroscopic correlation. The unique feature of this case report is multimodality imaging correlation with arthroscopy and histopathology findings. We have highlighted the pathognomonic imaging findings of this rare but benign intra-articular lesion and also discussed the differential diagnosis in detail.

Abstract: Pseudoaneurysms are common vascular abnormalities due to disruption of the vessel wall. Pseudoaneurysm with arteriovenous fistula is a rare presentation. Complications associated with them develop unpredictably and carry a high mortality rate. Traditionally pseudoaneurysms have been treated surgically. However, with the advent of new interventional techniques, management using endovascular approach have gained popularity in treating pseudoaneurysms. Here, we present two cases of large pseudoaneurysms with arteriovenous fistula treated by percutaneous stent graft. Present studies on pseudoaneurysms are all either iatrogenic or secondary to nephrologic dialysis treatment and only few present studies exist describing such large post-traumatic femoral pseudoaneurysms with arteriovenous fistulas were treated successfully by stent grafting through femoral approach, with good patency at 6 months follow up.

Abstract: Encephaloceles, while a common entity affecting 1:4000 live births, typically occur in the occipital region. Encephaloceles involving the frontal region comprise only 15% of all cases. Naso-orbital encephaloceles are rarely seen. Our case profiles a child born at term with an atrial septal defect (ASD), micrognathia, cleft lip, and frontonasal as well as bilateral naso-orbital encephaloceles. At birth the encephaloceles were undetected. During the cleft palate pre-operative preparation, the bilateral naso-orbital encephaloceles were diagnosed as dacrocystoceles for which the child underwent surgical repair. Misdiagnosis and loss to follow up lead to delayed surgical treatment until the child was almost two years of age; the right eye was near complete closure due to the increasing size of the encephalocele. This case highlights the importance of meticulous radiologic interpretation of midline nasal masses, as a correct diagnosis impacts clinical management and directs surgical repair.
