worth a thousand... differential diagnosis: lumbar cystic schwannoma. Marked peripheral ring-like enhancement with central area of low signal of the mass in T1-weighted postcontrast images. Sagittal plane.

Tumor and

tumorlike conditions of the pleura and juxtapleural region: review of imaging findings. Diagnosis: extramedullary hematopoiesis. Technique: chest CT and MRI. Description: A 42-year-old woman with sickle cell anemia was referred for a routine control examination. The axial CT in the mediastinal window setting (a) shows as incidental findings, two well-delineated paravertebral masses with a homogeneous hypodense aspect. There is no locoregional bone invasion. On both the axial T1 vibe MRI sequence with FS (b) and the axial T2 haste MRI sequence (c), the lesions have the same signal intensity as bone marrow. There is no contrast enhancement of the lesions on the axial T1 vibe sequence with FS (d)
