ABSTRACT Trigger wrist is a clinical entity characterized by triggering or the crackling of the wrist. Here, a case is reported of intrasyno- vial angiofbrolipoma that caused trigger wrist and carpal tunnel syndrome. This is the only case report where trigger wrist and carpal tunnel syndrome caused by the intrasynovial angiofbrolipoma were developed simultaneously. it is believed that that adhesive tenosynovitis developing in the tendons may have contributed to the triggering and carpal tunnel syn- drome in the wrist as a result of infammation occuring as a consequence of intrasynovial angiofbrolipoma. Key words: Intrasynovial angiofbrolipoma, tenosynovitis, trigger wrist Case Report Hand Microsurg 2016;5:107-109 doi:10.5455/handmicrosurg.204100 Trigger wrist and carpal tunnel syndrome caused by hand intramuscular intrasynovial angiofbrolipoma: A rare case report Turan C Dulgeroglu 1 , Yunus Guzel 2 , Hasan Metineren 1 , Huseyin Metineren 1 Introduction Trigger wrist is a clinical entity characterized by triggering or the crackling of the wrist. Suematsu et al. have identifed the etiological factors that lead to these entities under three main categories: type A - tumor; type B - anomalous in muscle body; and type C - anom- alous in tumor and muscle body [1]. Te case reported here was categorized as type A. Trigger wrist and carpal tunnel syndrome caused by intrasynovial angiofbroli- poma in association with fnger movements is a rare condition. In this report, a patient is described that has carpal tunnel syndrome developing in association with trigger wrist caused by intrasynovial angiofbrolipoma. Based on a review of the literature, this appears to be the frst case report where trigger wrist and carpal tun- nel syndrome brought about by intrasynovial angiof- brolipoma were developed simultaneously. Case Report A 40-year-old female patient was admited to the authors’ Orthopedic Clinic with complaints of trigger- ing of fnger fexion and extension movements in the wrist and numbness in the 1st, 2nd and 3rd fngers in the hand. Te complaints of the patient had been on- going for approximately one year. No foreign bodies were found in the wrist or hand of the patient by way of inspection and palpation. Ultrasonography (USG), Magnetic Resonanse Imaging (MRI) and Electroneu- romyography (ENMG) tests were requested for the patient. Intrasynovial mass diagnosis was made in the palm area of the intramuscular region with USG and Department of Orthopaedics and Traumatology, 1 Dumlupinar University School of Medicine, Kütahya, Turkey 2 Ordu University Medical School, Orthopaedics and Traumatology, Ordu, Turkey Yunus Guzel, MD, Department of Orthopaedics and Traumatology, Ordu University Medical School, Ordu, Turkey e-mail: dryg@windowslive.com October 12, 2015 / October 25, 2015 Author affliations : Correspondence : Received / Accepted : © 2016 Turkish Society for Surgery of the Hand and Upper Exremity www.handmicrosurgeryjournal.com Hand Microsurgery &
