Gliomatosis cerebri (GC) is a diffuse infiltrative neoplastic glial process with a devastating prognosis. Considering its rarity, unpredictable clinical manifestations, and lack of characteristic radiographic features, GC is a difficult diagnosis that is quite often delayed. In this report, we present a case of a 61-year-old man with a history of chronic alcohol abuse and atrial fibrillation who presented with right arm weakness initially presumed to be from an acute ischemic stroke. GC was not diagnosed until six months after initial symptoms and diagnosis was indicated when considering the neurocognitive findings in conjunction with suggestive radiographic findings. The presence of a rapid, expansile lesion in the cortex, corpus callosum, and infratentorial structures with mild parenchymal enlargement, as shown in our case, is more revealing of an invasive entity typical of GC rather than an ischemic process and other pathologies. This case demonstrates the fatal challenges of its prompt recognition and the therapeutic limitations for those patients presenting with advanced symptoms at the time of diagnosis. Recognizing GC in cases with such rapid multilobe clinical features with similar diffusely invasive patterns of growth on imaging can avoid a delay in diagnosis and improve patient quality of life., (© 2021 The Authors.

Background: Extrauterine ectopic pregnancy is a rare form of ectopic pregnancy, accounting for roughly 1:10,000-30,000 of all pregnancies. Primary omental pregnancy is the least common form of abdominal ectopic pregnancies, making it extremely rare. Typical presentation includes pelvic pain, secondary amenorrhea, with or without vaginal bleeding. Atypical presentations range from nonspecific pain to asymptomatic., Case: A 19-year-old woman presented to the emergency department after several syncopal episodes. She had a positive urine pregnancy test (serum hCG 446 IU/L). Her hemoglobin level was 10.6 g/dL. Due to lack of pain or bleeding, abdominal imaging was not indicated. A head CT scan rendered negative results. She was subsequently diagnosed with idiopathic headaches and anemia and was discharged. She returned to hospital 48 h later with vaginal bleeding and additional syncopal episodes. She was not experiencing any abdominal pain or discomfort. Her anemia worsened (hemoglobin 7.5 g/dL). For this reason, imaging was performed. It was significant for massive hemoperitoneum. Due to the imaging findings and worsening anemia, diagnostic exploratory laparoscopy was recommended to evaluate for ruptured ectopic pregnancy. Laparoscopic findings revealed large hemoperitoneum and a 10-week gestational sac attached to the greater omentum near the transverse colon. This exceedingly rare presentation of extrauterine ectopic pregnancy offered few clinical clues other than worsening anemia until imaging later revealed the abnormality. Ruptured ectopic pregnancy, a potentially fatal complication of pregnancy, should be included into the differential diagnosis of any gravid patient with syncope and anemia unexplained by extensive diagnostic workup., (© 2021 Published by Elsevier B.V.)

Aplastic anemia is a hematological disease with deadly complications related to pancytopenia if not treated in a timely manner. First-line treatment consists of immunosuppressive therapy or matched sibling donor (MSD) hematopoietic stem cell transplant. Step up treatment involves a matched unrelated donor (MUD) hematopoietic stem cell transplant (HSCT) alongside immunosuppressant conditioning. However, recent research suggests that there is improved success of MUD HSCT for severe aplastic anemia compared to immunosuppressive therapy. We present a case of an 18-year-old who was diagnosed with severe aplastic anemia who received numerous immunosuppressive therapy regimens prior to obtaining a MUD HSCT. Over a year after bone marrow transplant, the patient is doing well with no signs of rejection. This case creates an argument for the use of upfront MUD HSCT as a curative treatment for acquired aplastic anemia rather than initial treatment with immunosuppressive agents., Competing Interests: The authors have declared that no competing interests exist., (Copyright © 2021, Van Antwerp et al.)
