Abstract OBJECTIVE Choroid plexus carcinoma (CPCa) is an uncommon tumor rarely occurring in patients older than 2 years of age. The case reported herein represents the first documented example of a primary supratentorial, extraventricular CPCa in an adult. The scant literature regarding this topic is reviewed. CLINICAL PRESENTATION A 68-year-old woman presented with transient expressive aphasia. Magnetic resonance imaging demonstrated an avidly enhancing, left temporal, extra-axial mass with associated parenchymal cysts. INTERVENTION The tumor was gross-totally removed via a frontotemporal craniotomy. A diagnosis of CPCa was made on histological, immunohistochemical, and ultrastructural grounds. Postoperatively, the patient was treated by local radiotherapy and temozolomide. A magnetic resonance imaging scan 44 months after surgery showed no evidence of residual or recurrent tumor. CONCLUSION CPCa infrequently affects adults. Only rarely does it present as a supratentorial, extraventricular mass. Resection is the mainstay of therapy. Adjuvant radiation and chemotherapy are rational treatment options.

Leptomeningeal Spread

Abstract Background Choroid plexus carcinoma is an intraventricular neoplasm originating from the choroid plexus epithelium and is of rare occurrence in adults. However, owing to the low prevalence of choroid plexus carcinoma, there is very limited information about the disease entity and treatment. Here we report a rare case of choroid plexus carcinoma in an adult patient. Case presentation A 46-year-old South Korean (East Asian) male presented with low back pain, headache, and diplopia. Magnetic resonance imaging demonstrated enhancing mass lesion in the left trigone, cerebellar with leptomeningeal spread. Surgery was performed via left parietal craniotomy, and the lesion was histologically confirmed to be choroid plexus carcinoma. The patient received adjuvant craniospinal irradiation for remnant mass and leptomeningeal spread. Magnetic resonance imaging performed immediately after completion of the treatment revealed a partial decrease in the size of the tumor. However, the patient expired died as a result of acute respiratory distress syndrome before follow-up of long-term outcome. Conclusion Choroid plexus carcinoma with leptomeningeal spread in adults is very important for rapid diagnosis and treatment. In the case of the presence of leptomeningeal spread, craniospinal irradiation can be considered as a treatment method, but may have serious complications. Hence, the technique should be applied with care.

ABSTRACT A 5 yr old castrated male whippet presented with a unique presentation of ambulatory paraparesis and subsequent diagnosis of primary intracranial choroid plexus carcinoma, with metastases to the cervical, thoracic, lumbar, and sacral spinal cord segments. Magnetic resonance imaging was performed initially of the thoracolumbar vertebral column and was followed by MRI sequences of the brain for confirmation of the presence of a primary intracranial tumor. The dog was euthanized immediately following diagnostic imaging due to the severity of clinical signs and poor prognosis. Postmortem examination confirmed the presence of a primary choroid plexus carcinoma, with diffuse metastatic lesions to the spinal cord. To the authors’ knowledge, this is the first description of MRI findings of spinal cord metastasis of a choroid plexus carcinoma in a dog. Additionally, this case demonstrates primary clinical signs arising from metastatic lesions. This confirms the importance of extensive neuroimaging investigations when suspecting choroid plexus tumors and evaluating response to treatment regimens.

The Impact

Background The COVID-19 pandemic led to a widespread socioeconomic shutdown, including medical facilities in many parts of the world. The purpose of this study was to assess the impact on neuroimaging utilisation at an academic medical centre in the United States caused by this shutdown. Methods Exam volumes from 1 February 2020 to 11 August 2020 were calculated based on patient location, including outpatient, inpatient and emergency, as well as modality type, including computed tomography and magnetic resonance imaging. 13 March 2020 was designated as the beginning of the shutdown period for the radiology department and 1 May 2020 was designated as the reopening date. The scan volumes during the pre-shutdown, shutdown and post-shutdown periods were compared using t-tests. Results Overall, neuroimaging scan volumes declined significantly by 41% during the shutdown period and returned to 98% of the pre-shutdown period levels after the shutdown, with an estimated 3231 missed scans. Outpatient scan volumes were more greatly affected than inpatient scan volumes, while emergency scan volumes declined the least during the shutdown. In addition, the magnetic resonance imaging scan volumes declined to a greater degree than the computed tomography scan volumes during the shutdown. Conclusion The shutdown from the COVID-19 pandemic had a substantial but transient impact on neuroimaging utilisation overall, with variable magnitude depending on patient location and modality type.
