We report a new case of neuromuscular block overlap between Myasthenia Gravis and Eaton-Lambert syndrome. A 64-year-old man with a 4-months history of gait disturbance was admitted for ophthalmoplegia worsening during exercise and decreasing at rest. Clinical examination after exercise, revealed limbs weakness and areflexia, palsy of the left eye abduction and a left
ptosis
. The level of anti-acetylcholin-receptor antibodies was high. Electrophysiological explorations revealed a decrement at 3 Hz and a increment at 30 Hz, with a reduction in amplitude of the initial motor potential. This patient improved under a combination of
guanidine
and anticholinesterase drugs. From this case and 9 previously reported cases, we propose 4 criteria for the diagnosis of such neuromuscular blocks: 1) exercising symptoms and signs, including areflexia, 2) presence of anti-acetylcholin-receptor antibodies, 3) reduction of the amplitude of the initial motor potential, with a decrement at 3 Hz, and an increment at 30 Hz, and 4) clinical and electrophysiological improvement under
guanidine
and anticholinesterasic drugs therapy.

A 49-year-old woman presented with a left eye abduction-elevation defect and a bilateral internal rectus palsy of peripheral origin. Thyroid function, cranial computed tomographic scan, and cerebrospinal fluid examination were normal, as were the prostigmine test for myasthenia gravis and the
guanidine
hydrochloride test for myasthenic syndrome. Skull radiography showed osteosclerotic and osteolytic areas, with slight orbital distortion, and there was hyperactivity in an isotopic scan. A skill biopsy showed fibrous dysplasia. This case is an unusual example of fibrous dysplasia of the skull with neuro-ophthalmological symptoms but without
ptosis
, exophthalmos, or visual loss.
