ABSTRACT
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.
ABSTRACT
Cytomegalovirus (CMV) pseudotumour of the gastrointestinal tract, is a rare benign entity which is treated with antiviral medications and known to resolve spontaneously in a few cases. This is a case report of a 58-year-old man who presented with right lower quadrant abdominal pain. Contrast enhanced computerized tomography of abdomen and pelvis showed apple core lesion involving proximal transverse colon, ceacum, ascending colon, ileoceacal valve and terminal ileum. Synchronous carcinoma of colon was suspected. At laparotomy, there was growth palpable only in the proximal transverse colon. Histological findings of biopsy specimen revealed CMV pseudotumour. CMV pseudo tumour should be included in the differential diagnosis of apple core lesions of the colon even in immunocompetent adults. Endoscopy and biopsy are strongly recommended before surgery in colonic mass lesions to make a definitive diagnosis and to avoid unnecessary surgery.
