The most common site of metastasis in gestational trophoblastic disease (GTD) is the lung. To the best of our knowledge, arteriovenous malformations (AVMs) associated with pulmonary metastatic lesions are extremely rare in patients with GTD. Here, we report a case of a nineteen-year-old woman who presented with pulmonary AVMs which developed in the areas of pulmonary metastases, complicated by recent hemorrhage. [ABSTRACT FROM AUTHOR]

Spinal angiomyolipoma (AML) is a rare disease. It is often reviewed with spinal angiolipoma. Both are composed of vascular and mature adipose elements. However, only AML contains broader array of mesenchymal component. They are accounting for 0.14% to 1.2% of spinal tumors. They appear as fat containing hypervascular tumor located at epidural space of thoracic spine. Spinal AML is more frequently infiltrative and ofted occurs more ventrally than angiolipoma. Previous studies have employed conventional radiograph, myelogram, and CT scan for spinal AML studies. Recently, MRI has been used for spinal AML in a few studies. Here, we describe a case of typical thoracic spinal AML with a review of its MRI findings and other differential diagnosis for epidural spinal mass with similar characteristics. [ABSTRACT FROM AUTHOR]
