Stiff-Baby--an unusual manifestation of cytoplasmic body myopathy: report of one case.
A 2-month-old male baby was admitted to our hospital with episodic cyanosis and respiratory failure which required mechanical ventilation. He was found to have upper limb flexion rigidity and poor weight gain since one month old. Progressive muscle stiffness over the abdomen, chest wall, back and four limbs were also noted. He could not be weaned from the ventilator smoothly due to recurrent CO2 retention. Laboratory tests revealed a high serum creatine kinase level. Cytoplasmic body myopathy was confirmed by muscle biopsy. The unusual initial presentations of generalized stiffness and early onset of respiratory failure were quite different from those of patients reported in the literature, who had floppiness, muscular atrophy and weakness. Prednisolone and Vigabatrin were given and the patient showed slight improvement in muscle stiffness and spontaneous movement.
