Background:
Multiple spinal extradural meningeal cysts (SEMCs) are rare lesions. SEMCs communicate with the subarachnoid space through multiple dural defects and expand into the extradural space with progressive spinal cord compression.
Case Presentation:
We report a 5-month-old boy with hydronephrosis involving nine huge SEMCs that were distributed from the T1-L5 levels. Eight SEMCs, except for one small noncommunicating cyst, were exposed through laminoplastic laminotomy at the T10-L5 and T3-5 levels. Five transdural communications with dural defects were packed with a piece of autologous muscle and fibrin glue. Tenting sutures to lift up the dura to the vertebral arch were added to minimize the extradural dead space. Postoperatively, cord compression was relieved and hydronephrosis improved.
Conclusion:
In conclusion, packing of all dural defects and dural tenting sutures at a one-staged operation is useful in the surgical management of huge and multiple SEMCs in infancy.

Farmers can use multiple regression to determine the crop yield based on more than one factor, such as water availability, fertilizer, soil properties, etc. Here, the crop yield is the response or dependent variable as it depends on the other independent variables. The analysis requires the construction of a scatter plot...

In series, the positive terminal of one battery is connected to the negative terminal of another battery. Hence, the voltage of each battery is added to give the net voltage, which is increased because each battery boosts the electrons that enter it. The same current flows through each battery because they are connected in series.
