Atypical posterior reversible encephalopathy syndrome in a case of thrombotic thrombocytopenic purpura with Sjogren's syndrome.

Radiol Case Rep 2021 Jun 19;16(6):1552-1556. Epub 2021 Apr 19.

Department of Radiology, Yale New Haven Health System, Bridgeport Hospital, Bridgeport, CT.

Thrombotic thrombocytopenic purpura (TTP) is a rare hematologic disorder characterized by thrombotic microangiopathy. Neurologic symptoms are frequently seen in its presentation and the most common finding on neuroimaging of TTP is posterior reversible encephalopathy syndrome (PRES). Acute strokes, hemorrhages and atypical PRES are uncommonly seen. Our case reports the clinical and imaging details of a young male patient with TTP and Sjogren's syndrome, who made a complete recovery after aggressive plasmapheresis and immunosuppressive therapy with resolution of the imaging findings of PRES on follow up brain MR imaging. We briefly review the literature for the spectrum of imaging findings that can be seen on brain MRI with TTP.

High-resolution computed tomography temporal bone imaging in achondroplasia.

Proc (Bayl Univ Med Cent) 2021 Jan 28;34(3):419-421. Epub 2021 Jan 28.

Department of Radiology, Yale New Haven Health Bridgeport Hospital, Bridgeport, Connecticut.

Achondroplasia is a genetic condition caused by disordered endochondral ossification, which leads to rhizomelic dwarfism and midfacial hypoplasia. Additionally, several morphologic changes in the temporal bone are thought to at least partially contribute to hearing loss in these patients. We present a patient with achondroplasia who presented with hearing loss and was referred to radiology for temporal bone imaging. High-resolution computed tomography of temporal bones demonstrated several interesting morphological abnormalities characteristic of achondroplasia.

Chylous ascites in cirrhosis from retroperitoneal lymphoma.

Proc (Bayl Univ Med Cent) 2020 Oct 1;34(1):138-140. Epub 2020 Oct 1.

Department of Radiology, Yale New Haven Health Bridgeport Hospital, Bridgeport, Connecticut.

Chylous ascites occurs due to processes that elevate pressures within or obstruct the lymphatics in the retroperitoneum. In cirrhosis, spontaneous chylous ascites can occur but is uncommon. We describe a case of a 74-year-old man with cirrhosis from nonalcoholic steatohepatitis who presented with worsening abdominal distension and chylous ascites on paracentesis; an infiltrating retroperitoneal lymphoma was subsequently detected on computed tomography imaging.

Dunbar syndrome: An unusual cause of chronic postprandial abdominal pain.

Radiol Case Rep 2020 Oct 2;15(10):1747-1749. Epub 2020 Aug 2.

Department of Internal Medicine, NYC Health + Hospitals/Lincoln, 234 East 149 St, Bronx, NY 10451, USA.

Median arcuate ligament syndrome (MALS), also known as Dunbar syndrome, is a rare condition in which the celiac artery is compressed by the median arcuate ligament of the diaphragm. We hereby report a case of a 48-year-old female presenting with long-standing abdominal pain and ninety-pound weight loss who was found to have median arcuate ligament syndrome after extensive workup.

Moyamoya Disease in a Middle-Aged Hispanic Woman: A Case Illustration.

Cureus 2020 Jul 9;12(7):e9101. Epub 2020 Jul 9.

Diagnostic Radiology, Bridgeport Hospital-Yale New Haven Health Care, Bridgeport, USA.

Moyamoya disease is a rare cerebrovascular disease of unknown etiology, once known to be rare in the United States as compared to East-Asian countries, it is now an increasingly recognized cause of strokes in the United States, as the prevalence of the disease appears to be increasing. We describe a case of a 41-year-old Hispanic female patient presenting to our hospital with a stroke. She had two episodes of right arm weakness and clumsiness prior to presentation to the hospital that had resolved upon arrival. Despite a CT head negative for stroke, further imaging work-up was performed including MRI of the brain with magnetic resonance angiography (MRA) and conventional angiogram, which showed characteristic imaging findings leading to the diagnosis of Moyamoya disease. The patient subsequently underwent elective surgical intervention with Encephaloduroarteriosynangiosis (EDAS) procedure to prevent further complications.
