CA19-9 tumor marker response during treatment. (B) CT image from PET/CT scan before trastuzumab + lapatinib (red arrow: liver lesion, 2.4 × 1.4 cm). (C) MRI scan after 8 cycles of trastuzumab + lapatinib (red arrow: the same lesion, 0.7 × 0.9 cm

at the anterior mediastinum, liver, bone marrow, skull, and third lumber vertebra. Brain MRI revealed disease in the right orbital fossa extending to the middle cranial fossa, with no intracranial or cerebellar disease. The patient underwent fine

least one prior negative biopsy. 51 , 55 MRI Increasing interest is being shown in the role of multiparametric MRI in prostate cancer diagnosis. Recent evidence suggests a benefit of MRI-targeted prostate biopsy compared with standard transrectal

revealed a large hemangioma but no other suspicious lesions ( Figure 1A ). MRI of the abdomen and pelvis confirmed imaging evidence of a 9.4 x 8.4-cm hemangioma, but also showed 2 small lesions in the inferior right lobe of the liver with ring enhancement

imaging, because plain radiographs often fail to diagnose chordoma and CT and MRI often end at S2. 15 , 18 , 19 Invasion and compression of adjacent neurologic structures can result in myriad symptoms, including weakness, numbness, bowel and bladder

, which revealed a poorly defined hyperdense mass in the pineal region associated with moderate obstructive hydrocephalus. Follow-up MRI revealed a homogenously enhancing pineal lesion on T1-wighted images, inseparable from the tectum, that measured 3

presented with persistent headache; MRI showed a solid and cystic posterior fossa tumor with patchy contrast enhancement. Over the next 7 years she underwent 3 incomplete surgical resections before experiencing progression with persistent growth of residual

progressive lower extremity weakness and bladder dysfunction. MRI revealed an epidural lesion extending from L3 to S2 level. The lesion showed low T1 and high T2 signal without contrast enhancement, suggesting a cystic lesion with neural foraminal extension

right leg and scrotal lymphedema, and high-dose interferon followed by a subcutaneous interferon for 1 year. The patient was monitored with serial PET/CT, MRI brain, and clinical examination. In 2007, a left calf melanoma in situ was treated with WLE. In
