Both patients are doing well as respective 2 and 7-year follow-up.<br /><br /> Although rare, unstable SBP may present atypical cervical location that readily responds to surgical descompression/fusion and radiotherapy.<br /><br />Although rare, unstable SBP may present atypical cervical location that readily responds to surgical descompression/fusion and radiotherapy.<br /><br /> Melanotic schwannoma (MS) is a rare variant of peripheral nerve sheath tumor. MS commonly arises along the spinal nerve sheath. Patients most often experience pain along the dermatome of the affected nerve root. Symptoms development is usually insidious. About half of MS cases are associated with Carney complex, a multi-neoplastic disorder. The remaining cases arise spontaneously. About 10-44% of these tumors undergo malignant transformation.<br /><br /> We describe a case of hemorrhagic MS presenting as acute chest pain mimicking myocardial infarction, a presentation which has not yet been described in the literature. Neurologic examination did not reveal any abnormalities. Myocardial infarction was ruled out in the ER, and a chest CT angiogram was ordered for evaluation of PE or aortic dissection which revealed an intradural extramedullary dumbbell-shaped mass extending through the left vertebral foramen at the level of T8. MRI revealed a heterogenous mass that was hyperintense with T2 and hypointense with T1-weighted imaging. The patient underwent an open laminectomy of the left T8 and T9 vertebrae and gross total resection (GTR) of a hemorrhagic black tumor. Microscopic examination showed fascicles and nests of plump spindle cells with variable intracellular melanin. Immunohistochemistry showed the cells to be positive for S100, SOX10, HMB-45, and MART-1, confirming diagnosis of MS. Two months after the operation, the patient was doing well and is free of recurrence.<br /><br /> GTR is considered the optimal treatment for MS; radiotherapy and chemotherapy may be considered but have not been shown to improve patient outcomes.<br /><br />GTR is considered the optimal treatment for MS; radiotherapy and chemotherapy may be considered but have not been shown to improve patient outcomes.<br /><br /> When gunshot injuries occur to the spine, bullet fragments may be retained within the spinal canal. Indications for bullet removal include incomplete spinal cord injury, progressive loss of neurologic function including injury to the cauda equina, and dural leaks with impending risk of meningitis.<br /><br /> Here, we present a 34-year-old male with a missile penetrating spinal injury to the cauda equina. In addition to the computed tomography scan demonstrating retention of a bullet in the left L1/2 disc space, the scan suggested likely dural injury. The patient underwent a decompression/instrumented fusion with retrieval of the retained bullet fragment. A laminectomy was performed from T12 to L3, and at L1 and L2, a large traumatic durotomy was identified and repaired. The patient, unfortunately, continued to have bilateral lower extremity plegia with neurogenic bladder/bowel dysfunction at 1-year follow-up.<br /><br /> We discuss the operative management and provide an intraoperative video showing the bullet extraction and dural closure.<br /><br />We discuss the operative management and provide an intraoperative video showing the bullet extraction and dural closure.<br /><br /> Spindle cell lipoma (SCL) constitutes just 1.5% of all lipomatous tumors. [https://www.selleckchem.com/products/epibrassinolide.html see more] They typically occur in the upper back and shoulders. Here, we report a 37-year-old female presenting with a SCL in the dorsal epidural thoracic spine, during her 9<br /><br /> month of pregnancy.<br /><br /> A 37-year-old female presented with a subacute (2 months) progressive paraparesis during her <br /><br /> month of pregnancy. The MR showed a dorsal epidural mass at the D8 level. Following a cesarean section, the patient underwent a laminectomy for tumor excision. Microscopically, the lesion proved to be a SCL. At 5-year follow-up, there was no tumor recurrence.<br /><br /> SCL represents a variant of benign lipomas that may occur in the dorsal thoracic spine. Gross total excision may be followed by a benign clinical course without recurrence or malignant degeneration. Very atypical SCLs need closer follow-up to avoid the misdiagnosis of liposarcoma.<br /><br />SCL represents a variant of benign lipomas that may occur in the dorsal thoracic spine.

At presentation, three cases were plurihormonal, six cases were on medical treatment including thyroxine, and two cases were incidentally discovered. Imaging revealed macroadenoma in all cases. Seven cases underwent pituitary surgery, after which three achieved remission. Another case entered remission after adjunctive radiotherapy. Thyrotropin (TSH) immunostaining was demonstrated in six out of seven adenomas.<br /><br /> TSHoma is a rare functioning pituitary tumor with both silent and symptomatic presentations. Diagnosis can be established with biochemical and imaging features, even without dynamic tests.<br /><br />TSHoma is a rare functioning pituitary tumor with both silent and symptomatic presentations. Diagnosis can be established with biochemical and imaging features, even without dynamic tests.<br /><br /> Intracranial arachnoid cysts (ACs) are a cerebral spinal fluid (CSF) collection within the meninges. They typically arise during embryologic development. Some are stable overtime with little consequence, but large or growing cysts may require surgical intervention. The optimal surgical technique is debated and may be more technically challenging in the infant age group.<br /><br /> Our unique case report details a 10-month-old (6 months corrected age) infant who presented with a drastic increase in head circumference and was found to have midline shift and three cysts - one large and two smaller ones. He was treated with an innovative surgical approach combining stereotactic introduction of a catheter to facilitate subsequent flexible endoscopy allowing three separate cysts to be treated through one small surgical incision with no complications and a stable examination on 2-year follow-up.<br /><br /> Symptomatic ACs in the infant population that require treatment can be addressed with open surgery to fenestrate the cyst, endoscopic cyst fenestration, or cystoperitoneal shunting.
