Vitamin B12 deficiency presenting as pseudo-thrombotic microangiopathy: a case report and literature review.

Pseudo-thrombotic microangiopathy (pseudo-TMA) is a recognized, yet uncommon, clinical presentation of vitamin B12 deficiency. Patients with pseudo-TMA present with microangiopathic hemolytic anemia (MAHA), thrombocytopenia and schistocytes. They are often misdiagnosed as thrombotic thrombocytopenia purpura (TTP) and receive unnecessary therapy.

Nuclear Medicine to Evaluate Complications of Cerebral Shunts: Two Cases and Review of Literature.

We also hope to provide a comprehensive literature review on various imaging modalities, including nuclear medicine studies in evaluating cerebral shunt complications.
