The debate is still open; benign or malignant: a case report of a multifocal epithelioid haemangioma of fibula.

In this case, we report an epithelioid haemangioma (EH) of the fibula with ill-defined multifocal lesions and a resultant pathologic fracture. Based on radiographic appearance, these lesions were initially thought to represent a malignant process, such as primary malignant bone tumour, metastases or multiple myeloma. Osseous EHs are rare.

Right to left shunting through communications between the left superior intercostal vein tributaries and the left atrium: a potential cause of paradoxical embolism.

Objectives: To investigate the role of collateral venous pathways between the left brachiocephalic vein (LBV) and the left atrium through an arcade comprising the left superior intercostal vein (LSICV), left vertical vein (LVV), and pulmonary veins as a potential cause of paradoxical embolism.

Methods: A retrospective search was performed to find symptomatic patients with negative work up for paradoxical emboli whose chest CT or MR angiography by left arm contrast injection showed a visible right to left shunt through the LSICV/LVV collateral pathway (symptomatic group). We also evaluated the characteristics of this collateral pathway in 150 chest CT angiographies from general referrals (comparison group).
