Rob Kardashian Blanketed with Same Good Luck Charm as Lamar Odom

Rob Kardashian's hospital visit had a flash of Lamar Odom's near-death ER trip ... based on a revealing pattern.

Kris Jenner and Corey Gamble showed up at the West Hills Medical Center Wednesday night with a leopard print blanket in tow ... and it looked familiar.

You'll recall in October 2015, Lamar was wheeled in a gurney wrapped in the same patterned blanket ... which Khloe called a good luck charm that she believes helped save her ex-hubby's life.

We're told the blanket Kris brought to the ER wasn't Lamar's, but it was identical. Almost everyone in the family has one.

TMZ broke the story ... Rob checked himself into the ER after his rocky relationship with Chyna led to some pronounced weight gains and serious diabetes flare-ups.
