[A case of neurolymphomatosis]
1Scientific and Practical Clinical Center for Diagnostics and Telemedicine Technologies, Moscow, Russia.
Objective:
To demonstrate the potential of positron emission tomography with 18F-fluorodeoxyglucose in the diagnosis of a rare manifestation of lymphoma - peripheral nerve plexus lesions.
Material And Methods:
A 73-year-old female patient with B-cell small cell lymphoma, stage II B complained of progressive weakness in the lower and upper extremities. The patient was referred for 18F-FDG PET/CT to rule out disease progression and evaluate the effectiveness of the treatment.
Results:
The diagnosis of neurolymphomatosis was verified. Neurolymphomatosis differs from paraneoplastic, inflammatory, or drug-induced neuropathies both in terms of clinical manifestations and in terms of prognosis. Difficulties in diagnosis lie in the extreme variety of symptoms and the extensive differential diagnosis.
Conclusion:
18F-FDG PET/CT is a sensitive method for the diagnosis of neurolymphomatosis.
