A rapid evaluation is performed to rule out stroke. No other focal neurologic deficits are found except for a loss of fine touch sensation in a C6 dermatome pattern. Further evaluation reveals that the patient was recently sick with an upper respiratory infection. A biopsy is performed and shows destruction of the cell bodies of sensory nerves. Which of the following structures is most likely been damaged?? A: Meissners corpuscles, B: Dorsal root ganglion, C: Ventral root ganglion, D: Dorsal column, E: Lateral corticospinal tract,  <response>: This is a clinical vignette describing a 42-year-old woman with loss of sensation in her left arm and hand in a C6 dermatome distribution. She recently had an upper respiratory infection. A biopsy showed destruction of sensory nerve cell bodies. The key findings are:- Loss of sensation in a C6 dermatome pattern, indicating a lesion in the C6 spinal nerve root or dorsal root ganglion - Recent upper respiratory infection suggests a viral etiology- Biopsy showed destruction of sensory nerve cell bodies, which are located in dorsal root gangliaBased on the sensory loss limited to a single spinal nerve dermatome and biopsy results showing destruction of sensory neuron cell bodies, the most likely damaged structure is the dorsal root ganglion.B: Dorsal root ganglion
