Intraosseous entrapment of the median nerve is an uncommon complication of elbow dislocation and fractures. The condition is seen to occur in adolescent age group with a remote history of trauma. We report two rare cases of type 2 intraosseous median nerve entrapment. Though the diagnosis of median neuropathy is made with clinical tests and neurophysiological studies, however exact site of entr...

Peripheral ameloblastoma (PA) is a rare extraosseous odontogenic tumor with histological characteristics similar to those of the common intraosseous ameloblastoma. Two questions regarding PA remain: its histogenic origin and how to differentiate between PA and intraoral basal cell carcinoma. We describe a patient with PA. The result of immunohistochemistry showed cytokeratin (CK) 7-, CK14+, CK1...

Benign primary intraosseous meningioma presented as unilateral proptosis is a rare case in our settings. The reported occurrence is 1%-2% of all meningiomas. This type of tumour has numerous nomenclature that represents its location outside the dural component, such as ectopic, extracranial, calvarial and extraneuraxial. Although it is a benign entity, the tumour can cause significant disfigure...

Intraosseous ganglion cyst of the carpal bones represents a rare cause of wrist pain. We report a case of a 42 year-old, right-handed female, who presented with pain of the right wrist following a fall on the palm of the hand. Clinical study revealed a moderate swelling over the mid-section of the palmar face and pain through extreme ranges of motion of the wrist. Plain radiographs and CT-scan ...

Primary de novo intraosseous carcinoma of the jaws has been rarely reported. We present a new case of this unusual tumour and discuss its histopathological and clinical aspects. The subject was a 76-year-old man who was seen due to complaints of pain and the presence of gingival changes in the left mandible. A panoramic radiograph and computed tomography revealed a large mandibular radiolucency...

Primary extradural meningioma is about 1-2% of all meningiomas. Primary intraosseous meningioma is a rare form of intra-bone tumors that account for approximately 67% of extradural meningiomas. We report a primary intraosseous meningioma of a 69-year-old man who had headaches and a mass on right parietal scalp for the past few months. Remarkably, the brain tissue within the osteolytic cavity of...

Intraosseous mucoepidermoid carcinoma is a rare tumor which affects women more than men and is more common in the mandible. The radiological examination reveals a well-defined unilocular or multilocular radiolucent lesion. This tumor may resemble a glandular odontogenic cyst, particularly in incisional biopsies. The accurate diagnosis of these lesions is imperative because the subsequent treatm...

We studied 50 patients with fractures of the femoral neck, 33 intracapsular and 17 extracapsular. Intraosseous pressure was measured by a transducer within the bone to quantify blood flow, and intracapsular pressure by a needle introduced into the joint space. The mean intracapsular pressure was lower in the extracapsular fractures. In these, the mean intraosseous pressure in the femoral head w...

Intraosseous glomus tumors of bone are extremely rare. We report a case of an intraosseous glomus tumor of the ulna. The patient was a 25-year-old woman who had a three-month history of a palpable mass in her right forearm with spontaneous pain. Radiographs showed cortical hypertrophy and a shell-like bone formation surrounding the small osteolytic lesion within the cortex of the ulna diaphysis...
