Subperiosteal ganglion is uncommon and usually presents as an asymptomatic cystic mass attached to a bone. It may also cause aching pain (Fisk 1949; Byers and Wadsworth l970)or be an incidental radiographic finding (Grange 1978). Previous reports have emphasised the characteristic radiological appearance of cortical erosion with spicubes of subperiosteal new bone (Heyse-Moore and Grange 1979). ...

BACKGROUND To report an unusual case of subperiosteal bleeding of nontraumatic etiology. CASE DESCRIPTION A 48-year-old female presented with an acute protrusion of the left eye after nonaccomplished suicide by means of asphyxia using a cable around the neck. At the time of presentation, the MRI showed an orbital subperiosteal hematoma causing an exophthalmos. After conservative treatment, th...

Acute subperiosteal hematoma of orbit is a rare condition and its presentation with rapid severe diminution of vision is even rarest. Urgent intervention is required for these patients presenting with visual compromise. Needle aspiration is safe and simple procedure for management of such hematoma provided the patient presents early and does not have any associated complications. We present one...

A 10-year-old girl presented with an episode of seizure following oste omyelitis of the frontal bone and subperiosteal abscess due to frontal sinusitis. CT scan confirmed osteomeyelitis of the frontal bone and subperiosteal abscess. At surgery, the subperiosteal abscess and contiguous subdural abscess was drained and sequestrectomy of the affected frontal bone done. Broad spectrum antibiotics a...

The authors report the case of a 13-year-old patient with neurofibromatosis (NF-I), who suffered blunt trauma to the left tibia in 1993. The diagnosis of subperiosteal hematoma was made. Treatment consisted of temporary rest. There was a recurrence in 1996, and the subperiosteal hematoma was drained. In 1997, a shortening osteotomy of the left tibia was performed. However, massive gigantism wit...

BACKGROUND In cases of suspected mastoiditis, imaging is used to evaluate the extent of mastoid destruction and possible complications. The role of magnetic resonance imaging (MRI) in mastoiditis has not been systematically evaluated. PURPOSE To assess the diagnostic performance of MRI in patients with suspected acute mastoiditis. MATERIAL AND METHODS Twenty-three patients with suspected ac...

OBJECTIVE To determine the relationship between prior antibiotic use and the development of acute mastoiditis (AM) in children. DESIGN Retrospective review. SETTING Tertiary pediatric center. PATIENTS We identified 129 patients with AM who were admitted to our center between 1996 and 2005. MAIN OUTCOME MEASURE Proportion of children who developed AM. RESULTS A total of only 67 patient...

We describe a sixteen years old male patient that suffered a craniocerebral trauma and presented at the emergency room, with ocular pain, palpebral hematoma and left eye proptosis. Orbital computed tomography showed left subperiosteal orbital hematoma. A surgical drainage was performed. Subperiosteal hematoma of the orbit is a rare cause of proptosis; its early diagnosis must be made in order t...
