Study group discussion: Medial medullary syndrome and crossed paralysis

Which of the following are clinical features of medial medullary syndrome?

A. Ipsilateral numbness of arm and trunk
B. Horners syndrome
C. Ipsilateral 12th cranial nerve palsy
D. Contralateral pyramidal tract sign

Answer is C and D.

Medial medullary syndrome is due to the infarction of the pyramid causing contralateral hemiparesis of the arm and leg, sparing the face. This syndrome is rare.

If the medial lemniscus and emerging hypoglossal nerve fibers are involved, contralateral loss of joint position sense and ipsilateral tongue weakness occur.

Source: Harrison.

Does this syndrome have any other name?

Yes, it is also known as Dejerine's syndrome

Mnemonic: MD - Medical medullary syndrome is Dejerines syndrome

You can also remember the popular spice in India "MDH"
H stands for Hemiparesis and Hypoglossal involvement.

That's all!

  1. Hi, would like to clarify the statement written "A and B are features of lateral medullary syndrome". The loss of pain & temperature sensation for trunk and limbs should be contralateral instead of ipsilateral.
