Multidisciplinary approach to L3/L4 lumbar disc prolapse masquerading as focal limb myositis-a radiological challenge

Prolapsed intervertebral discs are commonly associated with back ache and sciatica. Management is often conservative with analgesia and physiotherapy. Nerve root injections and discectomy procedures are used where conservative measures fail. Majority of patients present with symptoms of pain and motor weakness; however, a few can present as focal myositis of lower limb muscles in the distribution of radiculopathy. MRI scans of limbs are rarely done in these cases but if done can confound the radiologist. Our case report emphasize the importance of multidisciplinary approach for a L3 nerve radiculopathy with confounding clinical presentation of focal lower limb myositis of unknown etiology.

“…Treatment can either be surgical or conservative. Oral corticosteroids with prednisone or prednisolone at a dose of 15-45 mg per day has been reported for its effectiveness in cases of unilateral calf hypertrophy induced by radiculopathy with combined focal myositis [3]. Early detection is critical in deciding the proper treatment option and necessary for preventing deleterious effects of progressive muscle pseudohypertrophy.…”

Radiculopathy commonly presents as pain in dermatomal distribution of involved nerve roots. It is often accompanied by sensory deficit such as paresthesia, hypesthesia, and/or weakness. Neurogenic muscular atrophy is also frequent. However, hypertrophic changes may develop because of denervation in rare cases [1]. Some cases of muscle hypertrophy have been reported for neurogenic causes such as lumbosacral radiculopathy [2-4]. This unusual clinical manifestation most frequently occurs in the calf Chronic lumbosacral radiculopathy usually presents with neurogenic muscular atrophy. Hypertrophic changes in accordance with neuropathy are rare. This case report introduces a case of unilateral pseudohypertrophy of calf muscle as a clinical manifestation of chronic lumbosacral radiculopathy due to denervation. The patient presented pseudohypertrophy of muscle resulting from right L5 and S1 radiculopathy due to idiopathic spinal epidural lipomatosis (SEL). Physicians should be aware that muscle hypertrophy, which usually has been regarded as a sign of myopathy, may denote the clinical sign of radiculopathy. Electromyography can be a valuable tool for differential diagnosis in such cases.

“…Treatment can involve surgery or can be nonsurgical. In nonsurgical treatment, an injection of botulinum toxin [ 13 ] and steroid medication [ 14 ] are effective. In surgical treatment, Gibson and Waddell [ 15 ] reported that microdiscectomy is the effective way to reduce radiculopathy and muscle hypertrophy.…”

Neurogenic muscle hypertrophy: a case report

Muscular hypertrophy is caused mainly due to myopathic disorder. But, it is also rarely produced by neurogenic disorder. A 74-year-old woman complained of right calf pain with hypertrophy for several years. Recent lumbar spine magnetic resonance imaging (MRI) showed central and lateral canal narrowing at the L4-L5 intervertebral space. Lower extremity MRI revealed fatty change of right medial head of the gastrocnemius and soleus, causing right calf hypertrophy. Electrodiagnostic examinations including electromyography and nerve conduction velocity testing demonstrated 5th lumbar and 1st sacral polyradiculopathy. Integrating all the results, the diagnosis was neurogenic muscle hypertrophy. Neurogenic muscle hypertrophy is very rare, but we recommend that clinicians consider this problem when a patient complains of lower limb hypertrophy and pain.
