✓ Lipomas of the infundibulum are extremely rare and may not be recognized radiologically, even on computerized tomography (CT) scanning, if the tumor is less than 20 mm in diameter. A questionable CT diagnosis in the presence of endocrinological symptoms may justify an operation by microsurgical technique on the retrochiasmatic region. In the case reported, microsurgical removal of a small infundibular lipoma was successfully accomplished.

The authors describe a minimally invasive technical note for the surgical treatment of primary intracerebral hematoma. Thirty-one patients with supratentorial intracerebral hematomas and no underlying vascular anomalies or bleeding disorders underwent treatment with a single linear skin incision followed by a 3-cm craniotomy. After evacuation of the hematoma, a matrix hemostatic sealant (FloSeal) was injected into the surgical cavity, and immediate hemostasis was achieved in all cases. A second operation was necessary in only 1 case. In this preliminary experience, a small craniotomy combined with FloSeal helped to control operative bleeding, reducing brain exposure and damage to the surrounding tissue while reducing the length of the surgery.

✓The differential diagnosis of anteromedial knee pain is extensive and can be associated with meniscal tear, medial collateral ligament sprain, or pes anserinus bursitis. An association between knee pain and a peripheral nerve sheath tumor has rarely been reported. The authors describe the case of a 44-year-old man with a saphenous nerve schwannoma who presented with vague pain in the medial aspect of his knee mimicking the clinical presentation of a meniscal tear.
