Introduction. Simple bone cyst or unicameral bone cysts are benign osteolytic lesions seen in metadiaphysis of long bones in growing children. Various treatment modalities with variable outcomes have been described in the literature. The case report illustrates the surgical technique of minimally invasive method of treatment. Case Study. A 14-year-old boy was diagnosed as active simple bone cys...

Owing to multiplanar imaging capabilities and excellent tissue characterization, MRI can facilitate definitive diagnosis of benign conditions of the female pelvis. The purpose of this chapter is to review the spectrum of common benign conditions of the female pelvis and to illustrate the MRI features of these conditions, with an emphasis on the key imaging characteristics to suggest accurate di...

Cystic lesions of the pancreas are increasingly being recognized due to the widespread use of cross-sectional imaging. The initial evaluation of a pancreatic cyst should be directed toward exclusion of a pseudocyst. Patients with pseudocysts generally have a history of acute or chronic pancreatitis, whereas those with cystic tumors most often lack such a history. Several types of cystic lesions...

Cystic and cavitary lung lesions constitute a spectrum of pulmonary diseases diagnosed in both children and adults. Cysts and cavities are commonly encountered abnormalies on chest radiography and chest computed tomography. High-resolution computed tomography (HRCT) of the chest frequently helps define morphologic features that may serve as important clues regarding the nature of cystic and cav...

We report 12 cases of renal cystic lesions that could not be diagnosed preoperatively. Sonography, computed tomography (CT), magnetic resonance (MR) imaging, and angiography were performed in all cases. Angiography was not helpful in evaluating cystic lesions, because all cystic lesions were hypovascular or avascular within the cystic mass. CT was useful in depicting the fine structural abnorma...

• Objective: To review the diagnosis and management of pancreatic cystic lesions. • Methods: Narrative review of the literature. • Results: Pancreatic cystic lesions are clinically relevant as some are precursor lesions to pancreatic adenocarcinoma. Mucinous cystic neoplasms and intraductal papillary mucinous neoplasms are 2 commonly encountered pre-cancerous pancreatic cysts. Many cysts are id...

A 25-yr-old male with cystic fibrosis sustained a fragility fracture of the left femoral neck, which required surgical correction. He had several risk factors for the development of low bone density and despite treatment with an oral bisphosphonate, his bone mineral density reduced further. The patient died 2 yrs after sustaining the fracture. Bone specimens obtained at post mortem demonstrated...

CONTEXT Cystic nephroma is a rare cystic tumor, which only recently has been recognized as an exclusively adult lesion. Mixed epithelial and stromal tumor of the kidney is also a rare, recently recognized, biphasic tumor composed of tubular and cystic elements embedded in grossly recognizable spindle cell stroma. The histogenesis of both lesions is unclear. OBJECTIVES To compare clinical phen...

(BGHs) are uncommon duodenal lesions, and account for approximately 5% of all duodenal masses (1). BGHs contain cysts on rare occasions, and only a very small number of cases of cystic BGH with accompanying computed tomography (CT) or magnetic resonance imaging (MRI) documentation have been reported (2-4). Imaging diagnosis of BGHs is usually a challenge, due to their nonspecific appearance. Th...
