Facial infiltrative lipomatosis.

Background: Although there are multiple case reports and small series concerning facial infiltrative lipomatosis, there is no composite radiological description of the condition.

Objective: Radiological evaluation of facial infiltrative lipomatosis using plain film, sonography, CT and MRI.

Materials And Methods: We radiologically evaluated four patients with facial infiltrative lipomatosis.

Imaging of recurrent brain tumors with trivalent (99m)Tc-dimercaptosuccinic acid - initial results.

There is considerable chemical and structural similarity between the widely used oncophilic substance pentavalent dimercaptosuccinic acid labeled with (99m)Tc [(99m)Tc-DMSA(V)] and the renal imaging agent trivalent [(99m)Tc-DMSA(III)]. Other renal imaging agents like diethyltriamine penta acetic acid (DTPA) and glucoheptonate labeled with (99m)Tc have been used for imaging brain lesions, mainly for brain tumor imaging. The aim of this study was to evaluate technetium labeled (99m)Tc-DMSA(III) for brain tumor imaging.

Mucocele of the sphenoid sinus.

The sphenoid sinus is the least common site of mucocele of all paranasal sinuses. It is very rare in children, especially in those younger than 12 years when pneumatization of the sphenoid sinus is completed. We report a case of histologically proven sphenoidal mucocele in a 5-year-old child.

Bone scan demonstrating metastasis to the breast from an ovarian carcinoma and a review of the literature.

Breast metastasis from a primary ovarian neoplasm is very rare. We report a case of breast metastasis along with involvement of the liver, spleen, and pelvis from ovarian carcinoma in a 54-year-old woman demonstrated by whole-body bone scanning. Ovarian metastatic deposits frequently show calcification, and a Tc-99m MDP bone scan could be useful in determining the extent of calcified soft tissue metastatic spread in these patients.
