Abstract
BACKGROUND

Entrapment of the temporal horn (ETH) is a rare pathologic condition. It is a kind of focal hydrocephalus caused by obstruction of flow pathway of cerebrospinal fluid. It is caused by various conditions, but ETH secondary to postoperative gamma-knife radiosurgery (GKS) is extremely rare.

CASE SUMMARY

A 52-year old previously healthy woman underwent resection of a large intraventricular meningioma. A small fragment of residual tumor with no obvious enlargement of the temporal horn was observed 3 mo after surgery, and she was referred for GKS. Two months after GKS, she complained of headache and progressive paralysis of the left limb. Magnetic resonance imaging revealed enlargement of the temporal horn. There was a second procedure to resect the residual tumor 8 mo after GKS. After the second procedure, she recovered smoothly. As of the date of this writing, she has remained in good condition.

CONCLUSION

This case reminds us that ETH should be considered in the treatment of intraventricular meningiomas, especially before GKS.

Core tip: Entrapment of the temporal horn (ETH) is a rare pathologic condition. Here we present a case of ETH secondary to postoperative gamma-knife radiosurgery (GKS) in intraventricular meningioma. A 52-year old women received gamma knife therapy 3 mo after first operation of intraventricular meningioma due to residual tumor. Then, ETH occurred 2 mo after GKS. A second operation to resect the residual tumor 8 mo after GKS was performed and the patient recovered smoothly. This case reminded us that ETH should be considered in the treatment of intraventricular meningiomas, especially before GKS.
