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...

Osteoma of the internal auditory canal (IAC) is an uncommon benign bone tumor. Its imaging features may be similar to other IAC lesions, such as vestibular schwannomas that are benign and usually slow-growing but sometimes life-threatening tumors. Thus, detecting IAC lesions and differentiating osteoma from other IAC lesions are both important clinically. We report a case of misdiagnosis of an ...

Chondromyxoid fibroma is a rare benign cartilaginous neoplasm that mostly affects the metaphyseal region of the long bones. The tibia, small tubular bones of the foot, the distal femur and pelvis are common locations, but involvement of the vertebral bones, especially the cervical vertebra, is very rare. Radiographic features show typical characteristics and this tumor often presents as a lobul...

BACKGROUND Eosinophilic granuloma (EG), one of the three clinical forms of Langerhans cell histiocytosis (LCH), is a benign inflammatory reaction to an unknown etiologic agent. It most commonly occurs in children and young adults. The most frequently involved bones are the skull, the ribs and the femurs. Alongside the cranium, the maxilla and mandible can also be affected. CASE DETAILS Herein...

Extramedullary plasmacytoma (EMP) arises outside the bone marrow and can be associated with multiple myeloma (MM). A 55-year-old gentleman, who presented with dyspnea and expiratory wheeze, was diagnosed and treated for asthma. A subsequent relapse 6 months later prompted an Otolaryngology consult. Preliminary findings showed a benign-looking nodular lesion at the subglottis. Work-up at our ins...

An aneurysmal bone cyst (ABC) is a benign lesion that often arises eccentrically from the metaphysis of long bones and which can expand tissue as it grows. It rare lesion, frequently appearing in lower limb. Localizations on hands feet are rarer limited to tubular bones.We report case 2-years-old girl initially admitted for hard dorsal immobile slightly painful swelling 5th metacarpal left hand...

It is well established that Technetiummethylene diphosphonate (Tc MDP) whole body bone scintigraphy (WBBS) can demonstrate multiple lesions with increased radiotracer concentration in involved bone. But it is hard to differentiate multiple benign osteolytic lesions from disseminated bone metastases. Even combined with medical history and multiple imaging results, clinical diagnosis of metastati...

Introduction. Nora's lesion or bizarre parosteal osteochondromatous proliferation is a rare benign bone neoplasm that usually localized on the small bones of hands. The paper was aimed at clinical, morphological and structural analysis case, second registered in Ukraine. Case report. A 42-year-old male patient presented with complaints painless swelling area distal 4th metacarpal limited mobili...

Central giant cell granuloma is an uncommon benign intraosseus lesion of jaws. Traditional treatment has been local curettage, although aggressive sub-types have a high tendency to recur. This patient report describes a recurrent central giant cell granuloma involving the body of the mandible in a 48-year-old-woman. Initial treatment of lesion consisted of curettage and peripheral ostectomy. Wh...

Here, we report a case of a 16-year-old female patient was referred with scalp swelling and headache. Her neurological examination was normal and imaging of the skull revealed a well-defined lytic lesion measuring 15 mm × 6 mm to the right of the frontal bone. She was operated on with a prediagnosis of Langerhans cell histiocytosis. A wide excision with negative margins was made and the defect ...
