Although the exact prevalence of cystic pancreatic lesions is unknown, it is estimated to be around 1% of the general population based on large scale observational imaging studies [1]. While cystic pancreatic lesions are increasingly diagnosed due to the widespread use of cross-sectional imaging modalities like computed tomography (CT) and magnetic resonance imaging (MRI), it is not known if th...

Congenital cystic lesions of the pancreas are rare findings. Furthermore, dermoid cyst of the pancreas is exceptionally uncommon. A review of the world literature showed that only 18 documented cases of dermoid cyst of the pancreas were reported so far. The pre-operative evaluation of this lesion is rather questionable, with definitive diagnosis taking place intra-operatively. Herein, we presen...

Cystic breast mass is one of the common conditions seen presented in any breast clinic. Evaluating such cystic breast lesions is very important. Malignant cystic tumors like mucinous carcinomas and papillary carcinomas have to be differentiated from common benign cystic lesions of the breast like fibrocystic lesions and papillomas. Malignant breast cancers that present as cystic lesions are see...

Cystic Hygroma is a well-recognized lesion in paediatric patients but it is very rare in adults. We report here a case of Cervical Cystic Hygroma in a 45 yr old male. The reasons to present this case are 1) Its rarity in adults 2) Unusual age of presentation 3) Simulates various benign and malignant lesions at this site 4) Is a diagnostic challenge and 5) Role of histology for definitive postop...

As cross-sectional imaging has become more common, there has been a marked increase in the incidental detection of cystic pancreatic lesions. It is estimated that more than a third of these are found in asymptomatic patients. Although knowledge of the natural history of cystic lesions is incomplete at this time, it is known that some cystic pancreatic lesions, including pseudocysts and serous c...

Introduction: A hydatid cyst of the head and neck is a very rare condition, even in areas where Echinococcus infestation is endemic.   Case Report: We report a rare case of primary hydatid cyst of the right maxillary sinus in a 40-year-old man. The initial diagnosis of the presence of a cystic mass was the result of physical examination and computed tomography (CT) scan. We resected the cystic ...

The present study aimed to compare two-dimensional (2D) and three-dimensional (3D) magnetic resonance cholangiopancreatography (MRCP) for the assessment of pancreatic cystic lesions. Between February 2009 and December 2011, 35 patients that had been diagnosed with pancreatic cystic lesions, which was confirmed by surgery and pathology, underwent pre-operative 2D or 3D MRCP for pre-operative eva...
