Lacunar infarct of the tegmentum of the lower lateral pons

A stroke with a somewhat unusual neurologic formula was correlated with a
small linear high-intensity T2 focus in the lateral tegmentum of the lower
third of the pons. The clinical features included dysarthria, staggering
gait, incoordination of handwriting, right facial weakness, nystagmus,
ocular overshoot, right appendicular ataxia, and left-sided dissociated
sensory loss for pain and temperature. Lacunar lesions of the tegmentum in
the region of the pontomedullary junction, while not uncommon, have not
been studied pathologically and have not been reported in the magnetic
resonance imaging literature, to my knowledge.
