Thrombotic thrombocytopenic purpura (TTP) is a known menace in hematology and is quite rare in practice with known triggers. Lately, in the COVID-19 pandemic, hematology has seen a new pathology amongst which TTP associated with COVID-19 messenger RNA (mRNA) vaccine is unique. We report a case of a 69-year-old male with multiple comorbidities who presented to the hospital with severe fatigue and shortness of breath. Labs were significant for thrombocytopenia, anemia, and hemolysis with schistocytes consistent with TTP with a second dose of BNT162b2 mRNA vaccine as a likely culprit been documented.

Wilkie's syndrome, also commonly known as superior mesenteric artery (SMA) syndrome, is an infrequent and rare cause of small bowel obstruction. It is caused by extrinsic compression of the duodenal segment of the intestine between the aorta and SMA, causing significant postprandial abdominal pain and vomiting. The literature suggests the incidence of 0.01% to 0.3%. We present here an atypical presentation of SMA syndrome in which a young patient presented to our tertiary setup with unusually constant abdominal pain and weight loss requiring invasive interventions.

Chilaiditi syndrome is a rare disorder comprising of the interposition of the gut between the diaphragm and liver. This can lead to a spectrum of gastrointestinal and respiratory presentations, primarily in the elderly population in whom the disorder is relatively more prevalent. We present a case of a 63-year-old man who presented to our setup with abdominal pain and shortness of breath and later got diagnosed with Chilaiditi syndrome. He was managed conservatively and showed complete resolution of the symptoms.
