“…Overall mortality (2.1% spd group / 10.7% sdd group) was slightly superior to previously published data (2.1-13.3%) [5,10,13,15,20] especially as we included all patients who died before follow up. [4,20]. This could especially been shown for elderly patients.…”

Subdural Drainage versus Subperiosteal Drainage in Burr-Hole Trepanation for Symptomatic Chronic Subdural Hematomas

BACKGROUND: Symptomatic chronic subdural hematoma (scSDH) is one of the most frequent diseases in neurosurgical practice, and its incidence is increasing. However, treatment modalities are still controversial. OBJECT: The aim of this retrospective single-center study is to compare for the first time two surgical methods in the treatment of subdural hematoma that have been proven to be efficient in previous studies in a direct comparison. METHODS: We analyzed the data of 143 scSDHs in 113 patients undergoing surgery for subdural hematoma with placement of subperiostal or subdural drainage after double burr-hole trepanation for hematoma evacuation. RESULTS: Overall, there were no statistically significant differences regarding general patient characteristics, preoperative and postoperative symptoms, postoperative hematoma remnant, rates of recurrences, mortality, complications, and outcome at discharge and at 3-month follow up between the groups. There was a close to significant tendency of lower mortality after placement of subperiostal drainage system and a tendency towards lower rate of recurrent hematoma after placement of subdural drainage system. CONCLUSIONS: Our study shows for the first time a direct comparison of two mainly used surgical techniques in the treatment of scSDH. Both methods proved to be highly effective, and general patient data, complications, outcome and mortality of both groups are equal or superior compared with previously published series. Because there is a clear tendency to less mortality and fewer serious complications, treatment with double burrhole trepanation, irrigation, and placement of subperiostal drainage is our treatment of choice in patients with predictable high risk of complications.

“…To date, there are few case reports involving anterior knee schwannoma. One previous case of anteromedial knee pain secondary to saphenous nerve schwannoma was initially misdiagnosed as meniscal tear [5]. Another documented case of anterior knee pain associated with a schwannoma of the saphenous nerve localized in the Hunter canal has been described [6].…”

Peripheral nerve tumors are relatively uncommon with schwannomas being the most common type. Schwannomas are usually benign encapsulated tumors composed of neoplastic Schwann cells that generally do not transform to malignancy. Many are discovered incidentally as solitary tumors. The cause is unknown. Most occur spontaneously, while some develop in association with genetic disorders such as neurofibromatosis type 2 or schwannomatosis. Schwannomas can occur anywhere in the body. They affect all ages, with peaking incidence between ages 20 and 50 years, without predilection to sex or race. Many are asymptomatic; however, presenting signs and symptoms, such as paresthesia and pain, are due to mass effect and direct nerve invasion. Diagnosing includes combinations of thorough physical examination, imaging modalities such as magnetic resonance imaging and surgical biopsy. Treatment depends on factors such as location of the tumor and severity of symptoms. Asymptomatic patients are treated conservatively while symptomatic patients undergo surgical resection with favorable prognosis.

“…Schwannomas may grow for years without any symptoms if there are no structures anatomically that restrict their growth. [5][6][7][8]11 Some schwannomas are symptomatic early, causing neurologic deficit by either compressing the nerve internally or over an anatomic structure. [5][6][7] In our patient the tumor was surrounded by a tight osseo-musculo-fascial compartment that includes anteromedial tibia, pes anserinus, and collateral ligament.…”

“…Anteromedial knee pain had been reported due to injury of the infrapatellar branch of saphenous nerve or schwannoma of the saphenous nerve at the thigh, but no cases have been reported due to the tumor in the infrapatellar branch of saphenous nerve. [11][12][13] Intraosseous schwannoma is a different entity where the tumor presents as an expansile lytic lesion with bone destruction. These tumors commonly occur in skull bones.…”

Schwannoma Presenting with Anteromedial Knee Pain and Bone Defect

Tumors of the peripheral nerve sheath including schwannomas are known for their rarity and can present with neurological deficit. We report an interesting case of schwannoma of the infrapatellar branch of saphenous nerve presenting with anteromedial knee pain and proximal tibial metaphyseal defect. A 26-year-old man presented with pain and swelling (for the past 2 months) in the anteromedial aspect of knee. Investigations revealed scalloping lesion in the anteromedial aspect of proximal tibia with sclerosed margins. Surgical exploration identified an encapsulated tumor lying over the defect in the proximal tibial metaphysis. Histopathological examination confirmed benign schwannoma and the patient became symptom-free after the surgery. Schwannoma of the infrapatellar branch of saphenous nerve can present with anteromedial knee pain. In patients with an eccentrically placed metaphyseal defect of the anteromedial tibia with sclerosed smooth margins, the possibility of nerve sheath tumors should always be considered.
