A low grade osteosarcoma of the colon.

Background: Soft-tissue osteosarcomas are very rare. Only three cases of extraskeletal osteosarcoma have been reported arising in colon and we report the first well differentiated one.

Language recovery after acute intracerebral hematoma in temporoparietal region.

Arteriovenous malformations are the most common cause of spontaneous intracerebral hemorrhages in older children. Intracerebral hematoma can cause serious lasting neurologic, cognitive, and language deficits, or even possible death. We present the case of a 16-year-old boy who had language impairments after suffering a large hemorrhagic stroke in the left temporoparietal region.

Criteria and procedures for breast conserving surgery.

Aim: Emphasizing circumstances that determine increasingly popular surgical approach of breast conserving surgery (BCS), used in lower grade breast tumors, while maintaining survival that is found when more radical procedures are used.

Patients And Methods: Several leading oncological protocols in the world are compared, using PubMed database, and our own experience. Data gathered are compared to conclusions of Consensus Conference on Breast Conservation (Milan, 2005).

Calcium at the carotid siphon as an indicator of internal carotid artery stenosis.

Objectives: Carotid siphon calcification is often visible on unenhanced head CT (UCT), but the relation to proximal carotid artery stenosis (CAS) is unclear. We investigated the association of carotid siphon calcification with the presence of CAS.

Methods: This IRB-waived retrospective study included 160 consecutive patients suspected of stroke (age 64 ± 14 years, 63 female) who underwent head UCT and CTA of the head and neck.
