In multiple myeloma following are seen except:: (A) Anion gap raised, (B) Lytic bone lesion, (C) Polyaicular pain, (D) M spike present with polyaiculopathy
Answer is A. Answer is A (Anion Gap Raised) Multiple Myeloma is associaitd with decreased Anion Gap. Hypoalbuminemia Multiple Myeloma and other paraproteinemic states like Waldenstorm's macroglobulinemia Lithium intoxication / Bromide intoxication Decreased Anion Gap is rare / uncommon and occurs due to accumulation of positively charged unmeasured cations which lower the anion gap This is impoant as it may mask a significant anion gap acidosis.
