HISTORY OF PRESENTING ILLNESS
FEVERDuration :10 months, on and off type, associated
with night sweats, no diurnal variation, not associated with rigors and chills.
relieved by antipyretics to reoccur a few days later.
Was associated with weight loss.
PAINH/O pain in the nape of neck for the last 7-8
months, started abruptly, having moderate intensity.
Dull and persistent pain, aggravated by movement around the neck with minimum relief with medication, no radiation.

C.T. SCAN SHOWING SOFT TISSUE WINDOW
Lytic areas with enhancing soft tissues on multiple vertebrae, ribs.
AXIAL SCAN:Large soft tissue component of intermediate density extending on right side. Involvement of posterior aspect is better appreciated.
SAGITTAL SCAN:Altered marrow signal density in T1 extending in right sided posterior element which shows intermediate signal density on T1 and T2

FINE NEEDLE ASPIRATION CYTOLOGY OF PALPABLE MASS :
Positive for malignancy.Possibility ranking high in the order being
multiple myeloma.
BONE MARROW ASPIRATION:
Marrow shows prominent plasma cells >20%. Other normal hematopoietic elements are reduced.
Plasmacytoma to be co-related with radiological findings and serum electrophoresis.

Diagnostic Criteria for MULTIPLE MYELOMA
MAJOR CRITERIA
I = Plasmacytoma on tissue biopsy.
II = Bone marrow with greater than 30% plasma cells.
III = IgG peak of greater than 3.5 g/dL or an IgA peak of greater than 2 g/dL, or urine protein electrophoresis (in the presence of amyloidosis) result of greater than 1 g/24 h
MINOR CRITERIA
a = Bone marrow with 10-30% plasma cells.
b = Monoclonal globulin spike present but less than category III
c = Lytic bone lesions
d = Residual IgM level less than 50 mg/dL, IgA level less than 100 mg/dL, or IgG level less than 600 mg/dL
The following combinations of findings are used to make the diagnosis of multiple myeloma:
I plus b, c, or d
II plus b, c, or d
III plus a, c, or d
a plus b plus c
a plus b plus d

MANAGEMENTChemotherapy.High dose chemotherapy or Bone marrow or
stem cell transplantation may be done. The 2011 NCCN MM guidelines added the
following therapies : Combination of:
1 Bortezomib/ cyclophosphamide/dexamethasone (primary induction therapy for transplant patients)
2 Bortezomib/dexamethasone (primary induction therapy for those who are not candidates for transplantation)
3 Melphalan/prednisone/lenalidomide (primary induction therapy for non transplant patients)
