“…Incidence of bone -muscle anomalies of the hand and forearm is within the range of 1/30.000 and 1/100.000 9. Whilst male-female ratio is 3:2, thenar muscle anomalies and thumb hypoplasias can be seen in isolation, as in Cavanagh’s syndrome and are commonly seen with syndromes such as Holt-Oram, TAR, Fanconi, VACTERL and radial bone anomalies 2,10–13. Cavanagh’s syndrome is a rare anomaly of the upper extremities that presents with unilateral or bilateral hypoplasia of the thenar eminence 2.…”

In this paper, we report a case of a 23-year-old male patient with bilateral absence of the flexor pollicis brevis and abductor pollicis brevis muscles with an intact functioning opponens pollicis and flexor pollicis longus muscles with bilateral thenar atrophy due to its rarity. All physical, neurological, ultrasonographic, direct radiographic, electromyographic and MRI studies were used to confirm and document this congenital anomaly.

“…CTH can be an isolated defect as in Cavanagh syndrome ( Cavanagh et al, 1979 ) or may be accompanied by cardiac abnormalities ( Holt and Oram, 1960 ) or ocular abnormalities ( Okihiro et al, 1977 ). Absence of radial artery has also been reported in association with CTH ( Fernandez et al, 2009 ). CTH may be unilateral or bilateral.…”

Ultrasonography in patients with congenital thenar hypoplasia (Cavanagh syndrome) and co-morbid carpal tunnel syndrome

Highlights Distinguishing congenital thenar hypoplasia (CTH) from severe carpal tunnel syndrome (CTS) is challenging. Electrodiagnostic studies may be non-localizing in severe median nerve entrapment. Ultrasound can reliably diagnose co-morbid CTS in CTH. Ultrasound provides insight into the pattern of thenar muscle hypoplasia.

“…Most commonly, this is associated with abnormal median sensory nerve studies and subsequently diagnosed as CTS. However, when median sensory potentials are normal and there is no clinical or electrophysiologic evidence of neurogenic thoracic outlet syndrome, cervical radiculopathy, distal myopathy, motor neuron disease or Lambert-Eaton Myaesthenic Syndrome, the electromyographer must consider anomalous innervations and congenital anomalies [8].…”

Objective: To summarize the literature on the electrophysiology of Cavanagh Syndrome (CS), to present a clinical application and to propose an updated electrophysiologic protocol. Methods:A systematic literature search for CS was carried out and a clinical application is presented.Results: CS is characterized by congenital thenar hypoplasia and can be associated with other regional muscular and vascular anomalies. The main electrophysiologic abnormality in patients with CS is a reduced amplitude median compound muscle action potential (CMAP) to the thenar eminence, which is also seen in CTS. Radiographic, and electrodiagnostic findings of a patient with co-morbid CS and CTS is presented. Evaluating the median CMAP to the first lumbrical may assist with the diagnosis of CTS in patients with CS. Conclusions:As CTS and CS can present with thenar atrophy and low amplitude CMAPs, electromyographers should be aware of the clinical and radiographic characteristics of CS and consider electrophysiologic evaluation of the first lumbrical.
