Primary Dural Lymphoma: Clinical Cases and Literature Review.

Primary dural lymphoma (PDL) is an extranodal non-Hodgkin lymphoma that accounts for less than 1% of all central nervous system lymphomas. Primary dural lymphoma grows from the dura mater, and it is often diagnosed as meningioma or acute subdural hematoma due to its radiological characteristics. Surgery is the gold standard of therapy; in many patients, PDL is relatively benign with good outcome. Authors report their experience in three patients affected by extranodal non-Hodgkin lymphoma (PDL) mimicking a meningioma.

Analysis of risk factors and postoperative predictors for recurrent lumbar disc herniation.

BACKGROUND: This study identified risk factors and postoperative indicators for recurrent lumbar disc herniations (rLDH) following microdiscectomy. METHODS: We retrospectively reviewed the 1-year recurrence rate for LDH in 209 consecutive patients undergoing microdiscectomy (2013-2018). RESULTS: Utilizing a multivariate analysis, higher body mass index (BMI) and postsurgery Oswestry disability index (ODI) were significantly associated with an increased risk of rLDH. CONCLUSION: Elevated postsurgery ODI and higher BMI were significantly associated with increased risk of rLDH.
