A 23 year old woman presented to the clinic with Raynaud's phenomenon and numbness and tingling in her right cheek, chin and the right side of her tongue. Examination showed altered facial sensation to touch and pinprick in the right V1-V3 distributions. When investigations revealed that her ANA was 1:5120 in a speckled pattern and anti- RNP was 243.79 U, a diagnosis of Mixed Connective Tissue Disease (MCTD) was made. MRI brain showed diffuse enhancement of the Trigeminal nerves bilaterally, right>left. Trigeminal sensory neuropathy is the most common CNS manifestation of MCTD and often the presenting symptom. Prognosis is variable, some features respond to glucocorticoids.
Raynaud’s phenomenon; Trigeminal sensory neuropathy; Mixed connective tissue disease
A 23 year old previously healthy woman presented to the clinic with initial symptoms suggestive of Raynaud’s phenomenon (Figure 1), followed a few weeks later by bitemporal headaches and numbness and tingling on her right cheek, chin and the right side of her tongue. She also complained of fatigue and itching all over her body. She had no rash, oral ulcers, joint pain, swelling or hearing loss.
On examination, facial sensation was altered to touch and pinprick in the right V1-V3 distributions. When investigations revealed that her ANA was 1:5120 in a speckled pattern, anti- RNP was 243.79 U, with negative anti- Ro/La, Sm, dsDNA and SCL-70, a clinical diagnosis of Mixed Connective Tissue Disease (MCTD) was made. MRI brain is shown below (Figure 2). Compared to the pre-contrast T1-weighted image (Figure 2A), diffuse enhancement of the Trigeminal nerves (short white arrows) is seen bilaterally, right>left, in the post-contrast images (Figures 2B and 2C).
Axial FIESTA sequence (Figure 2D) through the prepontine cistern and Meckel’s cave demonstrates asymmetric prominence of the right Trigeminal nerve (long white arrow).
Trigeminal sensory neuropathy is the most common CNS manifestation of MCTD and often, the presenting symptom [1,2]. Prognosis is variable, some features respond to glucocorticoids. No therapy is effective for trigeminal neuropathy ; anti-epileptics and antidepressants may provide some relief. For our patient, treatment with Corticosteroids and Rituximab resolved her headache completely, but she continued to have mild facial numbness.
