Primary hyperparathyroidism is a relatively common disorder with a myriad of end-organ manifestations, and surgical treatment remains the only curative option. Minimally invasive parathyroidectomy has replaced bilateral neck exploration as the standard technique for the majority of patients with solitary adenomas. Preoperative imaging is essential for accurate localisation of parathyroid adenomas. Four-dimensional computed tomography of the parathyroids has emerged as a useful problem-solving tool in the initial workup. This article reviews the underlying imaging principles, techniques, and practical tips on image interpretation and reporting, all of which are essential in successful preoperative localisation of parathyroid adenomas.

INTRODUCTION Both primary and secondary brain neoplasms are commonly encountered in neuroimaging. Glioblastoma is the most common primary malignant brain tumour in adults.1 Mortality remains high despite development of different treatment options with combinations of surgery, radiotherapy, and chemotherapy. The 2-year and 5-year survival rates after diagnosis of glioblastoma are reported to be approximately 26.5%2 and 5% to 10%,3 respectively. Evaluation of treatment response and detection of treatment-related complications are crucial in patient management and rely heavily on neuroimaging.

Introduction: We investigated whether omitting elective inguinal irradiation during neoadjuvant or adjuvant radiation/chemoradiation therapy is feasible for patients with low rectal cancer with anal canal invasion (ACI) and nonpalpable inguinal lymph nodes (ILNs) at presentation. Methods: Ninety low rectal cancer patients with ACI who underwent neoadjuvant or adjuvant radiation/ chemoradiation therapy with or without elective inguinal radiotherapy (RT) between 2011 and 2021 were recruited. None had palpable ILN. The failure pattern, ILN recurrence rate, survival data, and prognostic factors were analysed. Results: Among 81 patients omitting elective inguinal RT, the 3-year ILN failure rate was 4.9%. Meanwhile, there was no inguinal failure with elective RT. One case of isolated ILN failure was successfully salvaged by surgery. In multivariate Cox regression analysis, positive pathological lymph node(s) after neoadjuvant treatment predicted a worse locoregional recurrence-free survival (odds ratio [OR] = 9.066; p ≤ 0.001), distant metastasis recurrence-free survival (OR = 6.426; p = 0.002), and overall survival (OR = 11.750; p ≤ 0.001). Chemotherapy concurrent with RT was associated with better locoregional recurrence-free survival (OR = 33.338; p = 0.001) and overall survival (OR = 13.917; p = 0.006). Grade ≥3 acute and chronic toxicities occurred in 33.3% and 19.8%, respectively, of patients with elective inguinal irradiation, compared with 11.1% and 7.4%, respectively, in patients who did not receive it. Conclusion: Omission of elective inguinal irradiation resulted in a low inguinal failure rate and similar survival outcomes for low rectal cancer patients with ACI. Additionally, it might spare patients from unnecessary acute and chronic RT toxicities.

INTRODUCTION Menkes disease is a rare X-linked hereditary multisystem disorder due to a defect in copper metabolism caused by a mutation in the ATP7A gene.1 Patients can present with neurodegenerative manifestations and multiple connective tissue abnormalities.1 We report the case of a 4-year-old boy, known to have Menkes disease, who presented with an obstructive ureteric stone complicated by rupture of the renal pelvis.
