Splenic artery pseudoaneurysm; a cause or consequence: a case report.

BACKGROUND: Splenic artery pseudoaneurysm is a rare complication of recurrent pancreatitis usually presenting as an incidental finding on abdominal computed tomography. CASE PRESENTATION: We present the case of a 66-year-old north African male with a known history of previous pancreatitis who presented with upper gastrointestinal bleeding along with recurrent epigastric pain for 3 days. Investigations did not reveal any particular pancreatitis etiology. Computed tomography of the abdomen with contrast showed splenic artery pseudoaneurysm along with findings suggestive of acute pancreatitis. Upper and lower endoscopies failed to identify gastrointestinal the bleed source. The patient underwent intervention radiology embolization of the aneurysm sac with multiple coils via right retrograde common femoral artery-celiac access. The patient was discharged with a plan for capsule endoscopy in outpatient setting. CONCLUSION: Splenic artery pseudoaneurysm is a life-threatening complication and carries a high mortality rate if left untreated. Prompt identification through various imaging modalities, followed by urgent intervention, is crucial to avoid adverse outcomes.

First presentation of Graves' thyroid storm complicated by catastrophic antiphospholipid antibody syndrome: A case report.

Catastrophic antiphospholipid antibody syndrome is a rare and severe subtype of antiphospholipid syndrome with multisystemic organ failure due to thromboembolic events, resulting in high mortality rates. The association between catastrophic antiphospholipid antibody syndrome and autoimmune thyroid diseases is rarely reported in the literature. We report a case of a 35-year-old previously healthy female with Graves' thyroid storm, positive lupus antibodies, and probable catastrophic antiphospholipid antibody syndrome. Her hospital course was complicated by extensive venous thromboembolism, superior vena cava syndrome, thromboembolic strokes, and Takotsubo cardiomyopathy. Eventually, this led to an unfortunate death secondary to profound shock after 8 days despite emergent treatment. Our case report discusses the link between autoimmune thyroid disorders and catastrophic antiphospholipid antibody syndrome. We emphasize the difficulty in diagnosing catastrophic antiphospholipid antibody syndrome in extremely ill patients and stress the significance of considering it as a possible cause in thyrotoxicosis patients with multiple organ failure and hypercoagulability. Early recognition and prompt management are crucial in improving outcomes in these patients.

Atypical Presentation of Burkitt Lymphoma With Isolated Peritoneal Involvement and Association With Refractory Type B Lactic Acidosis and Hypoglycemia Secondary to the Warburg Effect.

Lactic acidosis is considered to be one of the most common causes of high anion gap metabolic acidosis in hospitalized patients. Warburg effect can present with type B lactic acidosis and is considered to be a rare but well-known complication of hematological malignancies. Here, we present the case of a 39-year-old male who had type B lactic acidosis and recurrent hypoglycemia secondary to newly diagnosed Burkitt lymphoma. This case highlights the importance of considering malignancy workup in any case of unexplained type B lactic acidosis with vague clinical presentation, which can aid in early diagnosis and management.
