Acute Lumbar Paraspinal Compartment Syndrome After Strenuous Exercise: A Case Report.

CASE: Acute lumbar paraspinal compartment syndrome (APCS) is rare. This case report describes the clinical presentation and magnetic resonance imaging (MRI) findings of APCS in a young man after strenuous weight training. The patient underwent surgical decompression of the paraspinal muscles with fasciotomy 4 days after presentation and made a complete functional recovery at the 3-month follow-up postsurgery. CONCLUSION: This case report highlights the importance of MRI in facilitating the diagnosis of APCS and demonstrates that fasciotomy, even if delayed, can result in complete functional recovery. This supports current understanding that surgical fascial decompression is the preferred treatment over conservative measures for this condition.

Idiopathic acute eosinophilic pneumonia.

A 44-year-old asthmatic male patient presented to the health centre with a 3-week history of coryzal symptoms, persistent productive sputum and shortness of breath. The chest X-ray (CXR) revealed symmetrical, perihilar airspace shadowed with peribronchial cuffing and bilateral reticular markings. The patient did not improve despite treatment, and hence a high resolution CT (HRCT) scan of the thorax was recommended. The HRCT showed smooth interlobular septal thickening, central perihilar soft tissue thickening and patches of ground glass changes. Both the CXR and HRCT findings, along with the symptoms and eosinophilia counts, were suggestive of idiopathic acute eosinophilic pneumonia (IAEP) which was confirmed on bronchoalveolar lavage. The patient was successfully treated with steroids. This case highlights the symptoms, diagnosis, management and treatment of IAEP. A rapid diagnosis of this rare disease is essential since it can be completely cured with correct management but can be fatal if left untreated. Once properly treated, this disease does not recur.

An unusual presentation of multiple myeloma.

The authors report a case of a 58-year-old woman, ex-smoker, who was referred to the respiratory clinic with a presumed unresolving airspace shadowing in the right lung. Further evaluation of the shadowing with a CT thorax revealed rib lesions, a pancreatic lesion and multiple liver lesions, making the diagnosis of metastatic pancreatic carcinoma most likely. However, further blood investigations and imaging eventually revealed the cause for the shadowing to be multiple myeloma, since the unresolving shadowing was actually a rib lesion.

The non-resolving lung cavity: a case of pulmonary cystic echinococcosis.

The authors report a case of a 20-year-old woman who was diagnosed with pulmonary cystic echinococcosis. She was admitted to hospital with a 1-week history of unresolving cough, coloured sputum with occasional haemoptysis and fever despite oral antibiotics. Radiology revealed a cavitating right lower lobe lung abscess. After 4 weeks of treatment, follow-up radiology showed incomplete resolution. Bronchoscopy revealed a white, avascular cystic lesion in the right lower lobe and serology testing for Echinococcus granulosus was positive. Repeat imaging eventually confirmed the cystic lesion with the 'air bubble'sign. A thorough travel history, a high index of clinical suspicion and close follow-up are essential in making a diagnosis of pulmonary cystic echinococcosis.

Benign cystic mediastinal teratoma presenting as a massive pleural effusion in a 17-year-old boy.

Mediastinal teratomas are a rare, albeit an important differential diagnosis of anterior/middle mediastinal masses in young adults and various atypical presentations have been reported. The authors report a case of a 17-year-old boy who presented with a 2-month history of worsening shortness of breath and pleuritic chest pain. A massive left-sided pleural fluid collection was seen on a chest radiograph (CXR). The pleural fluid was drained and a CT Thorax confirmed the presence of a cystic mass. Following re-accumulation of the fluid, thoracotomy was performed and a benign mediastinal teratoma excised. The patient remained well with no evidence of recurrence on follow-up CXRs a year post operatively.

Caseous mitral annular calcification mimicking a lung tumor on chest X-ray.

Mitral annular calcification (MAC) is a common condition of the mitral valve apparatus. A case involving caseous calcification, a rare variant of MAC is presented. This variant which has a benign course can present as an intracardiac mass and needs to be differentiated from more sinister causes of calcified cardiac masses such as tumor, abscess, and infective vegetation. Often, this requires multimodality imaging with echocardiography, computed tomography, and magnetic resonance imaging. Features of caseous calcification of the mitral valve on these imaging modalities are reviewed as the associations and clinical features.

Functional outcomes and recanalization rates of stent retrievers in acute ischaemic stroke: A systematic review and meta-analysis.

BACKGROUND AND PURPOSE: Intra-arterial therapy for acute ischaemic stroke has evolved rapidly in the last few years. Stent retrievers have now replaced 'first-generation' devices, which have been the principle devices tested in stroke trials.Our aims were to determine the rates of successful recanalization and functional independence in acute stroke patients treated with stent retrievers. We also sought to assess the safety outcomes of stent retrievers by assessing the rates of mortality and intra-cranial haemorrhage. MATERIALS AND METHODS: We conducted a systematic review and meta-analysis of studies which utilized stent retrievers as sole treatment or as part of a multi-modal approach in acute ischaemic stroke. RESULTS: We identified 20 eligible studies: 17 on Solitaire (ev3/Covidien, Irvine, California, USA) (n = 762) and three on Trevo (Stryker, Kalamazoo, Michigan, USA) (n = 210). The mean age of participants was 66.8 (range 62.1-73.0) years and the M:F ratio was 1.1:1. The average stroke severity score (National Institutes of Health Stroke Scale (NIHSS)) at presentation was 17.2. The weighted mean symptom onset to arterial puncture and procedural duration were 265.4 minutes and 54.8 minutes, respectively.Successful recanalization was achieved in 84.5% of patients with a weighted mean of 2.0 stent retriever passes. Independent functional outcome was achieved in 51.2% and the mortality rate was 16.8%. CONCLUSION: Stent retrievers have the potential to achieve a high rate of recanalization and functional independence whilst being relatively safe. They should be assessed in well-designed randomized controlled trials to determine their efficacy and assess whether they compare favourably with 'standard treatment' in stroke.

Imaging of adult ocular and orbital pathology--a pictorial review.

Orbital pathology often presents a diagnostic challenge to the reporting radiologist. The aetiology is protean, and clinical input is therefore often necessary to narrow the differential diagnosis. With this manuscript, we provide a pictorial review of adult ocular and orbital pathology.

Should PCNL patients have a CT in the prone position preoperatively?

OBJECTIVE: Lower pole percutaneous nephrostomy is performed frequently for percutaneous nephrolithotomy (PCNL), using a variety of imaging modalities such as fluoroscopic, computed tomography (CT) or ultrasound guidance. This study was performed to estimate the potential risk of colonic injury during lower pole percutaneous nephrostomy for PCNL. METHODS: We observed the position of the colon relative to the kidney in 134 patients who underwent CT kidney, ureter, bladder (KUB) examinations in the prone position. RESULTS: We found the prevalence of colon lying posterior to the kidney (i.e. retrorenal) in males to be 13.6% on the right, and 11.9% on the left, whilst in females it was 13.4% on the right and 26.2% on the left. CONCLUSIONS: Patients at higher risk for retrorenal colon should be considered for preoperative imaging to identify those patients in whom the colon may be situated posterior to the kidney, allowing for appropriate alterations in technique to be made, such as the use of ultrasound or CT guidance.
