Multidetector CT findings of calvarial eosinophilic granuloma

Multidetector CT findings of calvarial eosinophilic granuloma.

Eosinophilic granuloma (EG) is a well-recognised benign form of Langerhans-cell histiocytosis. The estimated incidence of EG is 3-4 per million of the population. More patients are children and adolescents between the ages of 1 and 15 years. The value of plain films in the diagnosis of the EG is limited and the extent of the disease is better defined by multidetector CT (MDCT) scanning. MDCT sc...

Eosinophilic granuloma of bone.

CT and MRI findings in calvarial non-infectious lesions.

Differential diagnosis of the calvarial lesions is important in order to decide whether biopsy, surgical intervention, or follow-up is required for further management. In this pictorial essay on calvarial lesions, lytic or sclerotic patterns, contours of the lesions, calcifications, soft tissue components, inner and outer table localizations were evaluated with computed tomography (CT). On magn...

Traumatic granuloma/eosinophilic ulcer.

Two case reports of an uncommon type of oral ulcerative lesion are presented. These lesions are of long duration, benign and reactive, and may clinically mimic a malignant ulcer. Histologically, these are deep lesions which exhibit 'pseudoinvasion' into skeletal muscle. There is a predominance of eosinophils while other chronic inflammatory cells such as plasma cells and histiocytes are in abun...

[Orbital eosinophilic granuloma].

PURPOSE To report the retrospective experience of a reference center in the diagnosis and treatment of orbital eosinophilic granuloma. METHODS A review of the files in the Opththalmic Pathology Laboratory, of the Hospital Universitário Professor Edgard Santos, Universidade Federal da Bahia, between 1974 and 2004, was conducted to identify cases of orbital eosinophilic granuloma. Data of diagn...
