Abstract
Vitamin B12 or cynacobalamin is an important water soluble vitamin which plays a key role in erythropoiesis,
proper nervous system functioning and for the metabolism of carbohydrate, fat and protein. Patients with
cynacobalamin defciency may present with haematological, gastro-intestinal, oral, dermatological, psychiatric and
neurological disturbances. We present a case of sub-acute combined degeneration (SACD) of spinal cord in a forty-
nine year old female presenting with one month history of progressive symptoms of lower limb paraesthesia, sensory
defcit, psychotic symptoms and postural instability. This case report is unusual as it elucidates the characteristic
triad, i.e., haematological, psychiatric and neurological symptoms in sub-acute combined degeneration of spinal
cord (SACD) associated with B12 defciency, correlation of its clinical manifestations, electrophysiological signs,
laboratory investigations ( especially biomarkers of B12 status) and spinal magnetic resonance (MR) imaging in
establishing the diagnosis, treatment outcomes, and potential therapeutic relevance of vitamin B12 replacement
therapy in symptoms remission.
Keywords: Vitamin B12; Dementia; Neuropathy; Spinal MRI; Sub-

Introduction
Vitamin B12 or cynacobalamin is an important water soluble
vitamin which plays an important role in erythropoiesis, proper nervous
system function and for the metabolism of carbohydrate, fat and
protein. Vitamin B12 (cyanocobalamin) is found essentially in animal
products including meat, fsh, eggs and dairy products. Other dietary
sources include B12 containing fortifed plant products such as cereals,
plant based milks, soy products and fortifed yeast extract [1,2]. Patients
with cynacobalamin defciency may present with haematological,
gastro-intestinal, oral, dermatological, psychiatric and neurological
disturbances. Tis case report illustrates the severity of B12 defciency,
causes, clinical manifestations, treatment outcomes, biomarkers of B12
status and potential therapeutic relevance of vitamin B12 replacement
therapy. Te purpose of this article is to highlight neuropsychiatric
symptoms in B12 defciency associated SACD, correlation of its clinical
manifestations, electrophysiological signs, laboratory investigations
and spinal magnetic resonance (MR) imaging, high index of suspicion
for its early diagnosis as delay in treatment can lead to poor neurological
recovery due to this subtle vitamin defciency.
Case Presentation
A 49-year-old female was referred to our hospital with two month
history of gradual progressive dementia, followed by social withdrawal,
mood swings and apathy. One month ago, abrupt onset of tingling in
the toes, pins and needle sensation of lower limbs up to trunk started.
She also complained of difculty in walking and progressive postural
instability. Te patient presented with confusion, mood lability, memory
and attention impairment and disorientation in time. Te patient’s
neuropsychological profle revealed impairment of her attentional,
reasoning and executive functions along with reduced performance at
the delayed free recall of the Rey’s list [Rey auditory verbal learning
test (RAVLT)]. Te score of the Raven’s matrices [Raven’s coloured
progressive matrices (RCPM)], Word fuency test, Weigl’s sorting test
(WST) and Mini mental state examination (MMSE) was also impaired.

Te score of the MMSE was 23. A careful history revealed that psychotic
or cognitive symptoms preceded neurological symptoms. (Gradual
progression of dementia and irritability started two months ago). Te
patient did not report any signifcant past history or family history of
psychiatric illness, gastrointestinal symptoms, pre-existing diabetes
mellitus, alcohol addiction, any medications which can decrease serum
Vit. B12 level or Nitrous oxide exposure. But, the patient revealed strict
preference for vegetarian diet and consumed lentils (Kesari). She had no
fever, weight loss, visual or bulbar symptoms, sphincter incontinence or
pain in the spine or limbs. On systemic examination, vital signs were
found to be normal but mild anaemia and glossitis was noticed. Deep
tendon refexes were normal. Sensation and joint position sense of the
distal part of lower extremities was impaired. Tough power and tone
of lower limbs were normal but vibration was impaired over ankle and
toes. Romberg’s sign was positive but Babinski’s sign and Lhermitte’s
sign were absent. Gait was evaluated as ataxic. All laboratory results
were within normal limits except vitamin B
12
, which was extremely low:
the patient had a serum level of 30 pg/mL (normal range: 200 to 835 pg/
mL). Peripheral blood smear examination showed anisopoikilocytosis
with macrocytosis blood picture. Hemoglobin was 11.0 gm/dl with
raised MCV (107.5 f). Random Blood Sugar, TSH, folate, LFT, LDH,
creatinine were all normal. HIV and VDRL- TPHA test were negative.
Titers of antibodies specifc for parietal cells were in the normal range.
