Hays; e-mail: ude. The pathomechanism of motor neuron degeneration in ALS has yet to be elucidated. Here we present a case of limb-onset ALS, with autopsy findings of Bunina bodies and skein-like inclusions, as well as sarcoid granulomas predominating among motor neurons.
Hays; e-mail: ude. The pathomechanism of motor neuron degeneration in ALS has yet to be elucidated.
The targeting of the motor neurons by the sarcoid inflammation raises questions regarding the role of cellular immunity in the pathomechanisms for ALS. Keywords: amyotrophic lateral sclerosis, sarcoidosis, autopsy, ubiquitin, TDP To our knowledge, there have been four case reports of clinical amyotrophic lateral sclerosis ALS and sarcoidosis. She had a 5-year history of urinary urgency with intermittent incontinence, and a few-month history of paresthesia in her arms.
The incontinence worsened in the months prior to our evaluation, possibly due to gait difficulty. Her paresthesia resolved spontaneously. She denied any other central nervous system symptoms. Examination revealed normal mental status, cranial nerves, sensory systems, and coordination.
Motor system examination revealed no fasciculations, but muscle tone was increased. Muscle atrophy was present in both the deltoid and intrinsic hand muscles.

Formal power testing showed diffuse weakness in the distal arm muscles with strength less than anti-gravity, and moderate weakness in the proximal arm muscles with strength against resistance. Strength in the legs was full except for hip and knee flexion, which were against resistance.
There was pathological hyperreflexia, including a brisk jaw jerk, bilateral Hoffman signs, and ankle clonus. The plantar responses are flexor.

Angiotensin-converting enzyme ACE was 69 reference 8 Chest x-ray from 3 months earlier was normal without hilar lymphadenopathy LAD. Magnetic resonance imaging Pneumoonia Spin Spin of the brain Pneumoonia Spin Spin cervical spine was unre-markable. Electromyogram EMG and nerve conduction studies obtained 8 months prior to our evaluation showed acute and chronic denervation in left arm myotomes and absent F waves Pneumoonia Spin Spin the ulnar nerve, which was initially thought to suggest left brachial plexopathy.
A second EMG obtained 1 month prior to our evaluation showed diffuse fibrillation and fasciculation potentials and chronic motor unit potential reinnervation with reduced motor unit recruitment in four extremities and fasciculation potentials in the thoracic paraspinal muscles. Repeat EMG showed active and chronic denervation in three limbs and thoracic paraspinals, sparing the tongue.
Valutab jalgravi liigese fluid CSF analysis showed 3 white blood cells and 0 red blood cells with normal glucose and protein.
The patient was started on Riluzole and Baclofen. In subsequent months, she developed increasing spasticity, limb dysfunction, and bulbar palsy along with pseudobulbar affect. She was transferred to hospice care and died 19 months from the onset of limb weakness.
Autopsy determined that the patient most likely died from aspiration pneumonia with mixed flora found in the left lung and a few Klebsiella pneumoniae in the right lung cultures.
Sarcoid-type noncaseating granulomas were present in both lungs and hilar lymph nodes. Neuropathology of the brain and spinal cord confirmed the clinical diagnosis of ALS. The nervous system demonstrated degeneration of the pyramidal tracts Fig. There was also loss of motor neurons and astrocytosis in the motor nuclei of cranial nerves VII and XII with sparing of the oculomotor nucleus.
Neuronal loss was present in the ventral horns and was most severe at cervical levels. Sparse surviving motor neurons contained intracytoplasmic Bunina bodies and skein-like inclusions which expressed ubiquitin Fig. However, to our surprise, small granulomas were found chiefly at sites of motor neurons, including the precentral gyrus, motor nuclei of cranial nerves V, VII.
Most granulomas in the precentral gyrus were located around or adjacent to venules, but these lesions were not clearly related to blood vessels in brainstem, spinal cord, or elsewhere.
A few granulomas were also found in the putamen and red nucleus, and they were seen rarely in the caudate nucleus, globus pallidus, thalamus, substantia nigra, and medullary tegmentum.
Uncharacteristically, the granulomatous lesions were observed rarely in their typical location for neurosarcoidosis, such as the leptomeninges and base of the telencephalon. Skeletal muscle was severely involved and included large tumor-like granulomas Fig.
