Background: Congenital fiber-type disproportion (CFTD) is a form of congenital myopathy. CFTD is rare, especially when presenting in patients with critical illnesses. Here, we report a case of CFTD presenting with type II respiratory failure after delivery and provide a review of the literature on CFTD.
Case summary: A 30-year-old woman was admitted to the obstetrics department of our hospital with premature rupture of the fetal membrane and with 7 h of regular contractions. After delivery, the patient experienced a refractory type II respiratory failure. Physical examination along with diagnostic procedures such as electromyography and biopsy confirmed CFTD. Use of invasive ventilator followed by intermittent use of noninvasive ventilator attenuated her symptoms. The patient recovered after ventilator-assisted respiration and was weaned off the noninvasive ventilator on the seventh day postpartum.
Conclusion: Congenital myopathy should be considered a differential diagnosis for type II respiratory failures that cannot be attributed to other diseases.
