3. Pathognomonic for 3°Syphilis

4. Lesion pretectal region of superior colliculus

Arnold-Chiari Malformation

1. Cerebellar tonsil herniation through foramen magnum = see thoracolumbar meningomyelocele

Barrett’s

1. Columnar metaplasia of lower esophagus (↑ risk of adenocarcinoma)- constant gastroesophageal reflux

Bartter’s Syndrome

1. Hyperreninemia

Becker’s Muscular Dystrophy

1. Similar to Duchenne, but less severe (mutation, not a deficiency, in dystrophin protein)

Bell’s Palsy

1. CNVII palsy (entire face; recall that UMN lesion only affects lower face)

Berger’s Disease

1. IgA nephropathy causing hematuria in kids, usually following infection

Bernard-Soulier Disease

1. Defect in platelet adhesion (abnormally large platelets & lack of platelet-surface glycoprotein)

Berry Aneurysm

1. Circle of Willis (subarachnoid bleed) Anterior Communicating artery

2. Often associated with ADPKD

Bowen’s Disease

1. Carcinoma in situ on shaft of penis (↑ risk of visceral ca) [compare w/ Queyrat]

Conn’s Syndrome

1. Primary Aldosteronism: HTN; retain Na+ & H2O; hypokalemia (causing alkalosis); ↓ renin
