Clinical presentation, radiology and histology are described and discussed. Given the unspecific clinical and imaging features, histology is crucial for the diagnosis.

We report a rare case of an intradural extramedullary teratoma arising in the region of conus medullaris in a previously healthy adult patient. The lesion was totally excised and the postsurgical outcome was favorable. Teratomas should be taken into consideration in the differential diagnosis in previously healthy adults with sudden onset of lower back pain or neurological deficits of the lower extremities and with a tumoral lesion of the spinal cord. Total surgical excision is the indicative treatment of choice.

Methods: With the knee in extension, we filled the intercondylar notch with paraffin, fixing the cruciate ligaments in their natural position, in 8 cadaveric specimens. The ACL-PCL tissue specimen, embedded in paraffin, was removed en bloc. Gross sections were prepared in the coronal plane and were evaluated histologically. The width, thickness, and cross-sectional area of both the ACL and PCL were determined. The dimensions of the semitendinosus tendon (ST), gracilis tendon (GT), and BPTB grafts were measured and compared with those of the native ACL. Results: The PCL occupies the largest part of the intercondylar area, leaving only a small space for the ACL in knee extension. The ACL midsubstance has a width of 5 mm, resembling a band shape. Only before its tibial insertion does the ACL fan out and take the form of its tibial attachment. The BPTB graft has a thickness of 5.8 mm, whereas the ST and GT grafts have a thickness of 6.25 mm and 4.5 mm, respectively, and are comparable to the midsubstance of the ACL but undersized in the tibial insertion (P ¼ .0016 for BPTB graft, P ¼ .002 for ST graft, and P ¼ .0003 for GT graft). A quadruple-looped ST-GT graft, with a diameter of 8 mm, is oversized in the midsubstance (P ¼ .0002) but fits better in the tibial attachment. Conclusions: The ACL midsubstance has a width of 5 mm, resembling a band shape. Before its tibial insertion, the ACL fans out like a trumpet, taking the form of its wide tibial attachment. Clinical Relevance: The dimensions of the native ACL have to be considered in graft selection for anatomic ACL reconstruction.
