Multiple pseudo-cyst formation is an uncommon manifestation of skeletal tuberculosis. Confusion has been caused by the failure to differentiate between this form of osseous tuberculosis, the solitary foci of diaphysial tuberculous osteitis, tuberculous dactylitis, and the bone lesions of sarcoidosis. This confusion has largely been due to Jungling (1920, 1928) who, believing them to be of tuber...

Hydatid disease or hydatidosis is the most widespread zoonosis caused by Echinococcus granulosus. Liver and lungs are the most common sites. Bone involvement is rare and reported in 0.5%-4% with spinal involvement reported in 50% of these cases. We present a case of spinal hydatidosis in a 35-year-old male presenting with lower extremity weakness and numbness. Magnetic resonance imaging (MRI) o...

Electrolyte alterations and extra-renal disorders are quite frequent in patients undergoing haemodialysis or peritoneal dialysis. The native kidneys may be the site of important pathologies in patients undergoing dialysis, especially in the form of acquired renal cystic disease with frequent malignant transformation. Renal neoplasms represents an important complication of haemodialysis-associat...

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...

In this study, the efficacy of computed tomography (CT) and magnetic resonance imaging (MRI) in the evaluation of craniospinal involvement with polyostotic fibrous dysplasia (PFD) in McCune-Albright syndrome (MAS) and related complications were reviewed. In CT, ground-glass appearance with well-defined borders was seen, with medullary widening and cortical thinning. More rarely, cystic/necrotic...

Background: Hydatidosis is a parasitic disease linked to the development of Echinococcus Granulosus larval form in humans. This anthropozoonosis characterized by many topographical and evolutionary aspects. Musculoskeletal hydatidosis rare, it represents only 0.9 2.5% all locations. Objective: aim this manuscript report rare case bone muscle location hydatid cyst show imaging cont...

Aneurysmal bone cysts (ABCs) are benign bony lesions frequently accompanied by multiple cystic lesions and aggressive bone destruction. They are relatively rare lesions, representing only 1% of bone tumors. The pathogenesis of ABCs has yet to be elucidated. In the present study, a series of 22 cases of primary and secondary ABC from patients treated in Department of Orthopedic Surgery, Kagoshim...

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...

Objective: The aim of this study was to compare the clinical and radiological results patients who treated combination Corticospongiosis dried frozen allograft (AG) with Demineralized Bone Matrix (DBM) AG in had bening cystic lesions (BCLs) nonunion.Materials Methods: This retrospective included a BCLs nonunion, underwent DBM / or during operation followed radiologically clinically. Patients we...
