“…Given the uncertain natural progression of teratomas, complete surgical excision is often considered the primary treatment approach. 22 This is the treatment of choice to prevent progressive worsening of the symptoms, as observed in our patient. Total resection is often utilized to prevent tumor recurrence, but in cases where it may result in neurological impairments or if a firm adherence to the spinal cord parenchyma is present, a subtotal resection might be preferred.…”

Key Clinical MessageIn conus medullaris, mature teratomas are rare. We report a case of a 40‐year‐old man who presented with urinary incontinence, low back pain, and muscle weakness. Magnetic resonance imaging revealed a mass in conus medullaris (T11–L1), further confirmed as a mature teratoma by pathological examination. We identified 63 cases of conus medullaris teratoma over the past two decades by systematically analyzing the case reports. Findings demonstrated that most cases were diagnosed in the fourth decade of life, with the majority of cases (57.6%) being male. Lower back pain, radiating pain in the extremities, hypoesthesia, and urinary dysfunction are the most common clinical presentations among patients with teratoma of conus medullaris. Mature teratoma is the dominant pathologic subtype of teratomas in this region, comprising more than 95% of cases. Our case highlights the importance of considering spinal teratoma as a differential diagnosis in patients presenting with urinary incontinence and lumbar pain.

“…Despite the fact that these tumors can appear in various locations, teratomas make up less than 1% of CNS tumors and are extremely rare in the spinal cord [6]. Since teratomas have an unpredictable natural progression, total surgical removal is often the main primary treatment [7]. Symptomatic recurrence in mature teratomas is uncommon, even in cases with subtotal resection, The recurrence rate has been reported at about 10%, predominantly seen in immature and malignant forms [8].…”

We presented an unusual case of a teratoma in a 76-year-old female who began four years ago with paresthesias and hypoesthesias in the sacral and gluteal regions. She denied weakness or gait instability. The magnetic resonance imaging showed an intradural lesion within the cauda equina at levels L2-L3. We decided to perform a posterior midline approach to the lumbar region to expose L2-L3 levels. After doing the L2-L3 laminectomy and the durotomy, we found a solid lesion surrounded by nerve roots with heterogeneous content. Through the meticulous separation of the nerve roots surrounding the lesion, we punctioned it, observing the exit of melanocytic material. Histopathological findings showed germinal neoplasia without immature neuroepithelium or malignant component; therefore, the diagnosis of mature teratoma was made. The patient was discharged without any aggregate neurological deficit. At the six-month follow-up visit, the patient continued with paresthesia in the gluteal region without motor weakness and reported minimal gait improvement.
