INTRODUCTION Scapulothoracic dissociation (SD) is a rare but severe injury to the shoulder girdle. It is characterised by complete disruption of the scapulothoracic articulation with lateral scapular displacement and intact skin.1-3 It is a spectrum of musculoskeletal and neurovascular injuries,3 involving high-energy trauma with lateral tractional forces applied to the shoulder girdle.2,4 Scapular Index (SI) is an indicator that is relevant to SD. It is obtained by measuring the distance from the spinous process to the medial border of the scapula, then divide the value of the injured side by the value of the non-injured side. Laterally displaced scapula with SI >1 has been commonly used as a diagnostic criterion for SD in previous studies.5 Nonetheless this requires a nonrotated anteroposterior (AP) chest radiograph that may be impractical in the urgent trauma setting. Moreover, SD may be initially missed in the polytrauma setting with multiple significant injuries.2 Herein, we report a case of SD in a young adult who was involved in a road traffic accident with polytrauma presenting with absent brachial pulse and significant vascular injuries on initial trauma computed tomography (CT) with CT angiogram.

Objective: We sought to determine the underestimation rates of ductal carcinoma in situ (DCIS) and of invasive ductal carcinoma (IDC), diagnosed as atypical ductal hyperplasia (ADH) and DCIS, respectively, occurring with stereotactic-guided vacuum-assisted breast biopsy (VABB) of suspicious microcalcifications. Methods: We retrospectively reviewed cases of ADH and DCIS diagnosed by stereotactic-guided VABB between 2010 and 2019 in our institution. The biopsy results were correlated with the subsequent surgical histopathology results. Results: A total of 44 ADH lesions and 83 DCIS lesions were sampled with stereotactic-guided VABB during the 10-year study period. All lesions were categorised as BI-RADS (Breast Imaging Reporting and Data System) 4. Most lesions had either 6 or 12 cores taken during the biopsy. The upgrade rate of VABB-diagnosed ADH was 18.2% (7 upgraded to DCIS and 1 to IDC out of 44 VABB diagnoses of ADH), while that of VABB-diagnosed DCIS was 9.6% (8 upgraded to IDC out of the 83 biopsy-diagnosed DCIS). Amorphous calcifications in ADH lesions were associated with a lower rate of malignancy upgrade (p = 0.019). No other predictors of upgrade for either ADH or DCIS were identified. When the pathology results of specimens without visible microcalcifications were reviewed separately, we found a very low rate of upgrade in the absence of histological microcalcifications or in the presence of a benign pathologic entity. Conclusion: A significant proportion of stereotactic-guided VABB-diagnosed ADH and DCIS were underdiagnosed when compared to surgical histopathology. Surgical excisional biopsy is recommended for all VABB-diagnosed ADH and DCIS lesions for definitive pathology.

Objective: We sought to compare three popular radiographic landmarks for their accuracy and inter-observer reliability in determination of the cavoatrial junction (CAJ) by analysing the anteroposterior scout and electrocardiogram-gated coronary computed tomographic angiography (CTA) images. Methods: CTA image data of 148 patients were assessed. The position of the CAJ defined by CTA was regarded as the gold standard. The median vertical distance between the CAJ and three radiographic landmarks (two vertebral body units [vertebrae plus discs] below the carina, the superior aspect of the right heart border, and the intersection of the bronchus intermedius with the right heart border) were assessed and compared using the Kruskal–Wallis test. For inter-observer reliability between two radiologists, each with at least 4 years of experience, intra-class correlation (ICC) was analysed. Results: The median vertical distances between the CAJ and two vertebral body units below the carina, the superior aspect of the right heart border, and the intersection of the inferior wall of the bronchus intermedius with the right heart border were 5.1 mm (0-24.6), 10.2 mm (1-45.2) and 9.8 mm (0.8-45.8), respectively. The radiographic landmark of two vertebral body units below the carina provided the closest estimation of the CAJ (p < 0.001). It also demonstrated higher ICC (0.931, 95% confidence interval [CI]=0.905-0.950) than the other two (0.833, 95% CI=0.768-0.880 and 0.860, 95% CI=0.805-0.899, respectively). Conclusion: Among the three popular radiographic landmarks for the CAJ, we found that a point two vertebral body units below the carina provided the most accurate estimate of CAJ location.

INTRODUCTION Gastrointestinal stromal tumours (GISTs) are the most common mesenchymal neoplasms of the gastrointestinal tract and more commonly found in middle-aged patients. They arise from the interstitial cells of Cajal in the myenteric plexus and are potential malignancies that can occur anywhere along the gastrointestinal tract, most commonly in the stomach (50-60%), followed by the small intestine (30-35%), colon and rectum (5%), and oesophagus (<1%).1 GISTs can also be extraintestinal and originate in the mesentery, omentum or retroperitoneum. In the Chinese population, the incidence among those aged ≥50 years is higher than in those under 50 years old with a mean age at diagnosis of 55.2 years.2 Most GISTs have a KIT or platelet-derived growth factor receptor alpha (PDGFRA) mutation. Neoadjuvant therapy with imatinib acts by blocking the signalling via KIT and PDGFRA. Nonetheless, 10% to 15% of GISTs do not have a detectable KIT or PDGFRA mutation and have a poor response to imatinib. Some are associated with neurofibromatosis type 1, Carney–Stratakis syndrome and Carney triad.3 Biopsy is preferred to confirm the diagnosis for large resectable tumours or metastatic GISTs. This article evaluates the radiological images of pathologically proven GISTs. RISK STRATIFICATION OF GASTROINTESTINAL STROMAL TUMOURS There are several guidelines for assessing the malignant potential of GISTs; the most common are the modified National Institutes of Health criteria and the Armed Forces Institute of Pathology criteria. In both guidelines, risk of recurrence varies with tumour size and mitotic rate. The presence of tumour rupture is an additional prognostic indicator. Intermediate tumours, i.e., large tumours with a low mitotic rate or small tumours with a high mitotic rate, that arise from the stomach have a more favourable prognosis than those in other parts of the gastrointestinal tract.4

Objective: Biopsies of cervical spinal lesions are often challenging procedures with significant risk of complications. Although computed tomography (CT)–guided biopsy of the thoracic and lumbar spine is considered a safe and accurate procedure, cervical spine biopsies are less commonly performed. The aim of this retrospective study was to evaluate the diagnostic accuracy of CT-guided needle biopsies for lesions of the cervical spine. Methods: Results of 27 CT-guided biopsies of cervical spine lesions performed between February 2000 and May 2020 in a tertiary care teaching institute in India were retrieved and analysed. Results: An adequate diagnostic yield was obtained in all 27 cases (100%). There were no major complications. The common pathologies, approaches to the lesions, and the method of biopsy were studied. Conclusion: CT-guided biopsy of the cervical spine with appropriate case selection and planning is a safe procedure with high diagnostic yield.

INTRODUCTION Bone marrow biopsy (BMB) is a standard bedside procedure used to evaluate haematological disorders and oncological diseases. Although rare, complications of this procedure are well documented. In 2003, Bain1 reported 26 adverse events in a total of 54,890 BMB procedures giving a complication rate of around 0.05%. Haemorrhage, reported in 14 patients, was the most frequent and serious adverse event, necessitating blood transfusion in six patients and causing death in one. There is no standard guideline for management of vascular injury following BMB. We report a case of inadvertent arterial injury during BMB that was successfully managed by embolisation through the biopsy needle.

Introduction: We assessed whether the communication of potential radiation risks from nuclear medicine examinations to patients, which is required by law, is adequate. Methods: We performed an audit to assess the adequacy of communication to patients, with two targets: (1) they received sufficient information about the potential radiation risks; and (2) they understood the information before they consented to the examination. We aimed at 100% of patients achieving both targets. If they did not, we planned to implement changes to bring our practice in line with these standards. A total of 53 patients undergoing examinations during a randomly selected week were recruited to fill out a questionnaire. Results: The audit showed that the targets were not achieved, with only 45% of the participants (95% confidence interval = 33-59%) reporting that they both received sufficient information and understood the potential risks. A series of changes were implemented, including distribution of a newly designed one-page information pamphlet to all participants, provision of a newly designed one-page reference sheet to the clinical team, and design of a new workflow for radiographers. Another 53 patients were recruited for re-audit, and the effect of the changes was assessed by comparing the results between the audit and re-audit, using the Chi squared test. These changes were associated with statistically significant improvements in both targets from 45% to 100% (p < 0.0001). Conclusion: When patients are provided with an easy-to-understand information pamphlet and the clinical team are instructed to assist patients in understanding the information, the communication targets are achievable.
