ABSTRACT
Primary synovial chondromatosis is a rare benign neoplastic process, in which cartilaginous nodules are produced in the subsynovial tissue. It has 3 main subtypes (intra-articular, tenosynovial and bursal). We present the case of a 61-year-old female, with a mass involving her right thumb for at least 5 years, which had recently increased in size. X-ray showed a soft tissue mass, without calcification or any underlying bony abnormality. Ultrasound and MRI showed a 6-cm mass surrounding the right flexor pollicis longus tendon of the right thumb. The patient went on to have surgical resection and was given a diagnosis of tenosynovial chondromatosis.
ABSTRACT
We present the case of a 17 year old football player with a 2 week history of left leg weakness and difficulty weight-bearing. Magnetic resonance imaging revealed a well-circumscribed lesion deep to the left iliacus muscle. The patient proceeded to computed tomography-guided biopsy. The likely diagnosis was that of a subperiosteal haematoma of the iliac wing, which was exerting mass effect upon the left femoral nerve resulting in leg pain and weakness. Imaging was repeated at an interval of 1 month, at which time the lesion had almost entirely resolved. Subperiosteal haematoma of the iliac bone is a rare entity but should be considered as a potential diagnosis in young adults, particularly where there is a history of trauma or recent sports injury.
ABSTRACT
INTRODUCTION: Sudden cardiac death (SCD) in young people is a rare but devastating event for families and communities. Ireland has previously had no measure of the incidence of SCD in young people. We report the incidence and causes of SCD in persons <35 years of age. METHODS AND RESULTS: We undertook a retrospective study of SCD between 2005 and 2007 in persons aged 15-35 years in the Republic of Ireland. We identified potential cases of out of hospital SCD through the Central Statistics Office (CSO) death certificate records. Autopsy, toxicology, and inquest reports were then obtained and analysed by an expert panel who adjudicated on the cause of death. A total of 342 potential SCD cases were identified through the CSO. Fifty were younger than 15 years of age, and 86 had either incomplete or unavailable post-mortem reports. Of 206 full reports obtained, 116 were adjudicated as cases of SCD. Cases were predominantly male (75%), with a mean age of 25.8 years (standard deviation 6.3). The incidence of SCD in this age range was 2.85 per 100,000 person-years (4.36 for males and 1.30 for females) and the incidence of sudden arrhythmic death syndrome (SADS) was 0.76 per 100,000 person-years. The commonest causes were SADS, 26.7% (31 of 116), followed by coronary artery disease, 20.7% (24 of 116), hypertrophic cardiomyopathy (HCM), 14.7% (17 of 116), and idiopathic left ventricular hypertrophy not fulfilling criteria for HCM, 10.3% (12 of 116). CONCLUSIONS: The incidence of SCD in the young in Ireland was 4.96 (95% CI 3.06, 6.4) for males and 1.3 (95% CI 0.62, 2.56) for females per 100 000 person-years. Sudden arrhythmic death syndrome was the commonest cause of SCD in the young, and the incidence of SADS was more than five times that in official reports of the Irish CSO.
