Cubital tunnel syndrome : a report of two cases

Cubital tunnel syndrome is the second most common peripheral neuropathy of the upper limb. This is due to the anatomy of the tunnel, the physiological changes that the nerve undergoes during elbow flexion, as well as pathological conditions that occur within the tunnel. We present two cases of ulnar neuropathy occurring at the level of the cubital tunnel, demonstrating that this entity may occur owing to an identifiable cause or may show only signal alteration without a visible cause on MRI.http://www.sajr.org.za/index.php/saj

Intra-articular rice bodies : imaging for persistent joint pain

Rice bodies are fibrous bodies that macroscopically resemble grains of rice. They may uncommonly occur as a complication of inflammatory arthritides but may create diagnostic confusion when the patient has no underlying inflammatory disease. The combined use of ultrasound, magnetic resonance imaging (MRI) and plain film makes it possible to reach a correct diagnosis. We describe a patient with a chronic monoarthritis of unknown aetiology who presented with rice bodies in the right elbow joint demonstrated on MRI.http://www.charpublications.co.za/C_JournalsORTH.as

A case of cyclist’s nodule in a female patient

There are few reported cases of cyclist’s nodule in females. The condition has thus lent itself to synonyms such as third, supernumerary or accessory testicle. We report the imaging findings of a perineal nodule in a 29-year-old female patient who is a known cyclist, and discuss the differential diagnosis.

Ulnar impaction syndrome : a case series and imaging approach

Ulnar-sided wrist pain can be attributed to many pathological processes. This can include traumatic, inflammatory or degenerative conditions. Ulnar impaction syndrome is a group of syndromes that are degenerative conditions of the wrist caused by an abnormal joint configuration or due to abnormal use. This leads to an increase in axial loading across the ulnar side of the wrist with resultant joint degeneration. The structures in the wrist concerned in this syndrome are the triangular fibrocartilage complex, the distal radio-ulnar joint and the lunate triquetral bones at their ulnar articulations. Even though a number of modalities exist to image the wrist, the options for accurately assessing ulnar impaction syndrome are limited and may be challenging. Accurate assessment of the triangular fibro-cartilage complex is essential, as it lies central in the classification of the disease.http://www.scielo.org.za/scielo.php?script=sci_serial&pid=1681-150X&lng=pt&nrm=isoam2017Radiolog

Acute obturator internus muscle strain in a rugby player : a case report

A 28-year-old male rugby player presented with severe onset of right hip pain when he fell awkward after a ruck during an international match. A rare case of an acute strain of the obturator internus muscle, a deep muscle of the hip joint, is reported, which resolved completely after a period of rest and intense active physical therapy.http://www.minervamedica.it/en/journals/sports-med-physical-fitness2016-09-30hb2016Sports Medicin

Iliopsoas haematoma in a rugby player

Traumatic iliopsoas haematoma is a serious complication of haemorrhage disorders rarely seen in young healthy athletes. It is mostly described in patients on anticoagulant therapy and commonly associated with various degrees of femoral nerve palsy. A 22-year-old male rugby player presented with severe onset of pain in the lower back, right hip flexor/pelvic area following a tackle during a rugby match. Magnetic resonance imaging identified a distinct, hyperechoic heterogeneous mass within the right iliopsoas muscle, confirming a diagnosis of iliopsoas haematoma. The case resolved completely after conservative medical treatment in addition to a period of rest and intense active physical therapy. This case study reports the rare diagnosis of an uncomplicated iliopsoas haematoma following a sports injury in a young athlete.http://sajsm.org.za/index.php/sajsmam2016Sports Medicin

MRI findings in chronic exertional compartment syndrome of the forearm : using signal intensity ratio as a diagnostic tool

BACKGROUND : Chronic exertional compartment syndrome (CECS) of the forearm is a rare but important cause of morbidity amongst athletes involved in strenuous upper limb activities. The diagnosis remains challenging due to the absence of objective, reproducible diagnostic studies. OBJECTIVES : To assess and quantify signal intensity (SI) changes of involved muscles in patients with CECS of the forearm compared to healthy control subjects competing in similar sporting disciplines. Also, to objectively measure MRI SIs within muscle compartments when using a pre- and post-exercise regime and calculating a signal intensity ratio (SIR) between post- and pre-exercise studies. METHOD : The study retrospectively examined MRI scans of patients treated for CECS of the forearm and compared these to the MRI scans of asymptomatic high-level rowers. A specific, reproducible pre- and post-exercise MRI scanning protocol was utilised in both patient and control subjects between 2011 and 2020. Signal intensities were evaluated pre- and post- exercise in involved muscle groups and ratios were calculated. RESULTS : A total of 86 SIs were measured (43 pre- and 43 post-exercise) in nine study participants (five patients and four controls). After post:pre-exercise comparisons, a statistically significant difference was found between control and patient groups (p = 0.0010). The extensor carpi radialis, flexor digitorum profundus and flexor digitorum superficialis muscles were most commonly involved. CONCLUSION : This study confirms that significant SI changes are apparent in patients with CECS of the forearm when making use of a standardised pre- and post-exercise MRI protocol. Furthermore, SIR may be used to accurately diagnose CECS of the forearmThe Capital Radiology Practice and the Pretoria MR Trust.http://www.sajr.org.zahj2022RadiologySports MedicineStatistic
