Differential diagnosis of brain lesions in a metastatic endometrial carcinosarcoma patient.

Ecancermedicalscience 2021 9;15:1182. Epub 2021 Feb 9.

Division of Advanced Internal Medicine, Department of Medicine, National University Hospital, National University Health System, 1E Kent Ridge Road, Singapore 119228, Singapore.

The differential diagnosis of ring-enhancing brain lesions in a patient with metastatic malignancy may initially seem straightforward, and easily attributed to brain metastases. On rare occasions, the physician needs to avoid anchoring bias by re-evaluating the entire clinical context in which these ring-enhancing brain lesions are found. We report a case of cerebral toxoplasmosis mimicking brain metastases in a patient with metastatic cancer and without a prior history of human immunodeficiency virus. Read More

Diffuse encephalitic toxoplasmosis in HIV.

BMJ Case Rep 2021 Mar 18;14(3). Epub 2021 Mar 18.

Department of Healthcare for Older People, Royal Devon and Exeter NHS Foundation Trust, Exeter, Devon, UK.

This case demonstrates an atypical radiological presentation of cerebral toxoplasmosis in a 62-year-old HIV-positive patient. The diagnosis is discussed alongside MRI imaging, laboratory results and treatment. Central nervous system toxoplasmosis is typically associated with ring enhancing lesions on neuroimaging with contrast, but the radiology for this patient shows diffuse white matter changes and ependymal enhancement, which would normally suggest an alternative diagnosis.

Toxoplasmic Encephalitis Followed by Primary EBV-Associated Post-Transplant Lymphoproliferative Disorder of the Central Nervous System in a Patient Undergoing Allogeneic Hematopoietic Stem Cell Transplant: A Case Report.

Transplant Proc 2020 Nov 29;52(9):2858-2860. Epub 2020 Aug 29.

Division of Hematology, Department of Internal Medicine, Hyogo College of Medicine, Nishinomiya, Japan.

Toxoplasmic encephalitis (TE) and post-transplant lymphoproliferative disorder of the central nervous system (CNS-PTLD) are major complications after allogeneic hematopoietic stem cell transplant (allo-SCT); both are fatal without timely diagnosis and disease-specific treatment. Differential diagnosis of TE and CNS-PTLD can be challenging because brain biopsy, a gold standard for diagnosis, is sometimes not possible, owing to poor patient condition after allo-SCT. Here, we describe a case of isolated CNS-PTLD arising during the therapeutic course of TE. Read More

Hospital Dr. Sótero del Río, Neurology Service, Av. Concha y Toro 3459, Puente Alto, Santiago, Chile.

Purpose Of Review: Space-occupying lesions represent a diagnostic challenge among people with the human immunodeficiency virus, acquired immunodeficiency syndrome (HIV/AIDS). To determine the best diagnostic approach to the wide array of possible etiologies and provide a thorough interpretation of neuroimaging in order to narrow a hierarchical differential diagnosis among these patients. Given that there is no pathognomonic neuroimaging pattern in this clinical setting, we searched results from brain biopsies to best determine the etiology of commonly found lesions. Read More

Cureus 2020 Jun 10;12(6):e8547. Epub 2020 Jun 10.

Infectious Disease, University of Alabama at Birmingham, Birmingham, USA.

Cerebral toxoplasmosis is a life-threatening infection most commonly found in immunocompromised hosts such as acquired immunodeficiency syndrome (AIDS) or transplant patients. However, it is not known to affect patients with chronic inflammatory disorders on immunosuppressive therapy. We describe the case of a 70-year-old female with rheumatoid arthritis (RA) on chronic therapy with methotrexate and infliximab, who presented to the hospital after two weeks of right-sided weakness.

IDCases 2020 15;21:e00767. Epub 2020 May 15.

University of Iowa Hospitals and Clinics, Iowa City, USA.

Toxoplasma gondii infection is an uncommon and potentially life-threatening condition in immunocompromised patients in the setting of solid organ transplantation. We present the case of cerebral toxoplasmosis which presented as a solitary intracranial space-occupying lesion in a patient who received a combined kidney and pancreas transplant more than twenty years ago.
