Extramedullary relapse of acute myeloid leukemia in the breast: A radiological case report.

This report presents a unique case of a 42-year-old female with a history of acute myeloid leukemia (AML) who exhibited an extramedullary relapse in the breast. Given the rarity of such presentations, this case underscores the importance of considering AML in the differential diagnosis of breast lesions, especially in patients with a pertinent medical history. Additionally, this case highlights the radiological and pathological challenges in distinguishing AML from other breast malignancies. The importance of timely diagnosis and the clinical implications of such a presentation are also discussed.

Axial melorheostosis: A rare presentation.

Melorheostosis is a rare sclerosing bone dysplasia that most commonly affects the lower extremity long bones in a sclerotomal distribution. Melorheostosis of the spine is a particularly rare manifestation of this disease. In the appendicular skeleton, melorheostosis has a pathognomonic imaging appearance of flowing hyperostosis resembling melted candle wax flowing down the margins of a candlestick. In the spine, it can have a variety of imaging manifestations from unilateral focal sclerotic lesions resembling enostoses, to more bulky and deformative hyperostosis that span and fuse multiple adjacent spinal segments. This combination of nonaggressive radiologic features makes melorheostosis a particularly important diagnosis for radiologists to understand so that they may spare their patients unnecessary biopsy. Here we present the clinical features and computed tomography findings in a 33-year-old male with spinal melorheostosis involving the first and second cervical vertebrae.

Multifocal epithelioid hemangioma of the metacarpal bones: A case report.

Epithelioid hemangioma of bone is a rare, locally aggressive but benign vascular tumor that is now recognized as a distinct entity from other vascular neoplasms. It is often difficult to distinguish on imaging studies from other vascular tumors, including epithelioid hemangioendothelioma, which can lead to misdiagnosis and inappropriate treatment. We present the characteristic features and multimodality imaging findings in the case of a 24-year-old female with multifocal epithelioid hemangioma of the first and second metacarpal bones with extension into the surrounding soft tissue.
