Solitary plasmacytoma

Case contributed by Dr Prashant Gupta

Presentation

Bilateral lower limb tingling since one month, no h/o trauma

Patient Data

Age: 50
Gender: Male
Modality: MRI

Expansile soft tissue lesion involving only the L1 vertebra is iso-hypointense on T1 and hyperintense to muscle on T2.

CT spine

Modality: CT

A correlation CT was performed. There is an expansile soft tissue lesion involving only the L1 vertebra. Prominent residual thickened trabeculae are seen giving a "MINI BRAIN" appearance.

Case Discussion

Although many vertebral lesions show low signal on t1 with high signal on t2 the "mini brain" sign is considered to be fairly characterestic of a solitary plasmacytoma.

Some authors consider it typical enough to forego a biopsy and start treatment.
