title: Endometrial osseous metaplasia: an evolving cause of secondary infertility.
abstract: OBJECTIVE
  To present an endometrial osseous metaplasia case and reemphasize that the condition is a cause of secondary infertility.
  
  
  METHODS
  Case report.
  
  
  METHODS
  Department of Obstetrics and Gynecology in a university hospital in Turkey.
  
  
  METHODS
  A 33-year-old multiparous woman was admitted to our institution with secondary infertility that had lasted for 2 years. She had experienced one first-trimester and one second-trimester abortion, 3 years and 2 years ago, respectively. On transvaginal sonography, a linear curvy echogenity was observed.
  
  
  METHODS
  Hysteroscopic examination revealed multiple bony spicules, extending perpendicularly from the posterior uterine wall in to the uterine cavity and occupying almost two thirds of the cavity. Thereafter, a resectoscopic excision of the bony spicules was performed.
  
  
  METHODS
  A normal endometrium and uterine cavity.
  
  
  RESULTS
  Two weeks after the operation, ultrasonographic evaluation was in the normal range, and the patient currently is trying to conceive spontaneously.
  
  
  CONCLUSIONS
  Although the role of office hysteroscopy in the evaluation of infertile couple is still under debate, clinicians should keep this rare disorder in mind, especially in patients with a history of late abortion, and should evaluate such cases by hysteroscopy when sonographic features are encountered.
