Answer: E A 27-year-old male with no medical illness presented to the orthopaedic clinic with left knee pain since 1 week. There was no history of trauma. There was no tenderness or swelling on physical examination and the range of motion of the left knee was normal. Frontal and lateral radiographs of the left knee (Fig. 1) were obtained, which showed an eccentric and well defined radiolucent l...

This case series study demonstrates the possibility of successful implant rehabilitation without bone augmentation in the atrophic posterior maxilla with cystic lesion in the sinus. Sinus lift without bone graft using the lateral approach was performed. In one patient, the cyst was aspirated and simultaneous implantation under local anesthesia was performed, whereas the other cyst was removed u...

This article describes osteoarthritis of the knee and a giant intraosseous cyst of the medial femoral condyle in an 83-year-old man that was treated successfully with total knee arthroplasty and autologous bone grafts. The patient presented to the authors' hospital with a 2-year history of right knee pain. A plain radiograph of the right knee revealed grade 3 medial compartment osteoarthritis w...

INTRODUCTION Intraosseous lipoma is a rare benign bone disease. Long and cancellous bones are the most locationsthat can be affected. Almost all lesions were discovered incidentally on imaging modalities that were done during an unrelated investigation. As it is rare, it may be mistaken for nonossifying fibroma, aneurismal bone cyst, simple bone cyst, bone infarct or chondroid tumors. Recently ...

  Ganglion cysts are the most common wrist tumors, and 60 -70% originate dorsally from the scapholunate interval.  Ossification of these lesions is exceedingly rare, with only one such lesion located in the finger reported in the literature. We present a case of an ossified dorsal wrist ganglion in a 68-year-old woman.  

The solid variant of aneurysmal bone cyst (solid ABC) is rarely encountered in long bones and appropriate treatment for this disease remains unclear. We experienced a 13-year-old boy suffering from pain in his left knee caused by solid ABC. Simple curettage of the bone lesion without any adjuvant therapy and a bone graft gave immediate pain relief. Histological examination of the surgical speci...

Aneurysmal bone cyst is a rare benign cystic bone lesion with an incidence of only 0.14 per 100,000 individuals and most commonly affects the metaphyses of long bones, spine, and pelvis. We present a very rare case of a 17-year-old boy with a rapidly expanding aneurysmal bone cyst arising from the first rib, resulting in neurogenic thoracic outlet syndrome secondary to its compression of the br...

A neurysmal bone cyst was first described by Jaffe and Lichtenstein in 1942. It is considered a benign, locally aggressive lesion with a potential for local recurrence, and it typically appears in the metaphysis of the long bones and in the vertebral column. Mostly, children and young adults are affected. No sex predilection has been observed. Radiographically, aneurysmal bone cyst is seen as a...
