The Brain

SummaryBrain scintigraphy with 99mmTc pertechnetate and subsequently with 6 7Ga citrate was carried out in 55 selected patients. Among 29 patients with normal 99mTc scintigrams, eleven suffered from intracranial tumours and in five of these, visualization of the tumour was obtained by means of 6 7Ga scintigraphy.Of 20 patients who showed abnormal 99mTc scintigrams as well as abnormal 6 7Ga scintigrams, eighteen suffered from intracranial tumours and two from infectious lesions of the brain.The remaining six patients who had abnormal 99mTc scintigrams but normal 6 7Ga scintigrams all suffered from vascular insults of the brain.It is concluded that 6 7Ga citrate often accumulates in tumours which are missed by 99mTc scintigraphy, and that 6 7Ga is not accumulated in areas of vascular insults of the brain as is 99mTc.

ABSTRACT A case is reported of intermittent hypercalcaemia, hypophosphataemia and severe skeletal rarefaction with cystic changes. An occult calcium malabsorption was found. Fat, triolein and iron absorption and radiological examinations were normal. There was gross intestinal mucosal atrophy. She was shown to be in a state of negative calcium balance and this was reversed by vitamin D. A gluten-free diet also improved calcium absorption. It is postulated that the patient had severe secondary hyperparathyroidism as the skeleton reverted to normal after six months of medical treatment.

Suprasellar tuberculomas are uncommon causes of intracranial tumours worldwide, even in areas endemic for tuberculosis. Often, they present with combinations of pituitary hormone involvement, which can lead to various complications due to hypopituitarism. We present a rare case of suprasellar tuberculoma leading to diabetes inspidus.

Radiological Examinations

Objectives As a cross-section discipline within the hospital infrastructure, radiological departments might be able to provide important information regarding the impact of the COVID-19 pandemic on healthcare. The goal of this study was to quantify changes in medical care during the first wave of the pandemic using radiological examinations as a comprehensive surrogate marker and to determine potential future workload. Methods A retrospective analysis of all radiological examinations during the first wave of the pandemic was performed. The number of examinations was compared to time-matched control periods. Furthermore, an in-depth analysis of radiological examinations attributed to various medical specialties was conducted and postponed examinations were extrapolated to calculate additional workload in the near future. Results A total of 596,760 examinations were analyzed. Overall case volumes decreased by an average of 41 % during the shutdown compared to the control period. The most affected radiological modalities were sonography (–54 %), X-ray (–47 %) followed by MRI (–42 %). The most affected medical specialty was trauma and orthopedics (–60 % case volume) followed by general surgery (–49 %). Examination numbers increased during the post-shutdown period leading to a predicted additional workload of up to 22 %. Conclusion This study shows a marked decrease in radiological examinations in total and among several core medical specialties, indicating a significant reduction in medical care during the first COVID-19 shutdown.

Abstract Introduction To present and discuss the clinical presentations, investigations, and treatment options for skull bone tumors. Materials and Methods This study was conducted from January 2019 to December 2019 at the Department of Neurosurgery. During this period, eight patients presented with skull bone tumor in the outpatient department. All patients were thoroughly investigated. Surgery was conducted on six patients and two patients had disseminated carcinoma; hence, surgery was not done. Patients were regularly followed-up after the surgery. Results In our study, out of eight cases, five were females and three were males. We had two cases of fibrous dysplasia, two cases of osteomas, and one case each of brown tumor, metastases from lung carcinoma, metastases from follicular carcinoma of thyroid, and Ewing sarcoma/primitive neuroectodermal tumor (PNET). Excision of tumor was performed where indicated and adjuvant chemo- and radiotherapy was suggested wherever required. Conclusion Bony tumors of the skull are uncommon diseases for the neurosurgeons. These tumors require a careful diagnosis with suitable radiological examinations and proper clinical correlation for proper management.
