Intracranial epidermoid cysts are rare. We report a case of a 55-year-old man who presented with trigeminal neuralgia and was found, on imaging, to have an epidermoid cyst located in the right middle fossa. He was managed via an entirely endoscopic endonasal approach. Postoperative magnetic resonance imaging confirmed complete removal of the mass, and the patient continued to have complete resolution of symptoms at a 1-year follow-up.

Abstract We describe the case of a 42-yr-old female patient with a 2-yr history of headache that has progressively worsened. Physical examination revealed no neurological deficit. Magnetic resonance imaging showed a large tumor of the left lesser sphenoid wing that enhanced with gadolinium and produced displacement of the midline and the Sylvian fissure. A thorough analysis of the origin of the tumor was done to establish the surgical strategy. With the patient positioned supine with the head slightly turned to the right side, fixed in a 3-pin head clamp, a pterional craniotomy was performed. Since the origin of the tumor is in the lesser wing an early extradural devascularization of the tumor was done with drilling out all the hyperostotic bone of the lesser sphenoid wing, including the lateral base of the anterior clinoid process. Intradural debulking and resection showed the effect of extradural devascularization with an important decrease in bleeding, allowing the total resection of the tumor. An immediate postop magnetic resonance showed a complete removal of the tumor. The patient presented a paresis of the oculomotor nerve that completely resolved in the 3-mo follow-up. In the following video illustration, we narrate this operative case and highlight the nuances of this approach.1 The patient has given assent and written consent for videos, images, or clinical or genetic information to be published.

Benign phyllodes tumour (BPT) of the prostate is a very rare neoplasm. It is composed of hyperplastic and neoplastic glandular stromal proliferation. Patients with BPT of the prostate generally present with lower urinary tract symptoms and hematuria. BPT of the prostate can potentially cause recurrent obstructive symptoms. Complete transurethral resection (TUR) and close postoperative follow-up is recommended. A 59-year-old man presented with dysuria and obstructive urinary symptoms. Flexible cystoscopy revealed prostatic hyperplasia and a polypoidal lesion originating from the right lateral lobe of the prostate. Magnetic resonance imaging revealed a 3 × 2.5-cm mass lesion in the right lateral lobe of the prostate. TUR of the prostate was performed and the pathological examination revealed benign prostatic hyperplasia and benign phyllodes tumour of the prostate.

We report the first clinical case on the successful use of proton beam therapy in the management of malignant transformation of intracranial epidermoid cyst. A 43-year-old man was initially diagnosed as this disease with left facial paresis, hypesthesia and hypoalgesia in the territories of the trigeminal nerve. After failure of surgical interventions, he was referred to our radiation centre. We performed a postoperative proton beam therapy for treatment. We delivered a total dose of 57 GyE in 31 fractions. He tolerated the treatment well with mild acute toxicities and remained healthy and functional by 2-year follow-up postradiotherapy. No evidence of delayed radiation-induced neurotoxicity was observed.

A retrorectal epidermoid cyst is an uncommon congenital lesion that arises from the remnants of the embryonic tissues. This type of cyst is difficult to diagnose before surgery. In this study, we report a rare case of a giant retrorectal epidermoid cyst in a 30-year-old woman. Initially, the condition was diagnosed as a perianal abscess and treated with incision and drainage. Since the abscess recurred, a pelvic magnetic resonance imaging was ordered, which revealed an 8.2 cm perianal cyst with appearance not compatible with an abscess. Postsurgical histologic analysis confirmed a retrorectal epidermoid cyst. Postoperative course was uneventful, and the woman was discharged on postoperative day 3. She was doing well at 4 months of follow-up. This report suggests that retrorectal cysts should be considered in cases of recurrent perianal swellings/abscesses.

Abstract Background: Schwannoma is a rare benign tumor of peripheral nerves arising from Schwann cells of the ubiquitous nerve sheath. Objective: To describe the operative steps and technical aspects of robotic laparoscopic resection of pelvic schwannoma. Methods: We describe 2 patients with pelvic schwannoma: a 34-year-old woman with schwannoma of the right lumbosacral trunk and a 58-year-old woman with schwannoma of a left S1 nerve. Pain was the main symptom in both patients. The diagnosis was confirmed by magnetic resonance imaging and nerve biopsies. Both patients were operated on by robotic laparoscopy. Results: Lesions were totally enucleated after incising the epineurium. After dissection of the schwannoma, the vascular pedicle and nerve fascicles involved were identified, coagulated, and then sectioned. The remaining fascicles of the nerve were preserved. The postoperative course was uneventful in both patients. With follow-up of 9 and 13 months, both patients obtained complete pain relief with no neurological sequelae. Conclusion: Robotic laparoscopic resection of pelvic nerve tumors such as schwannomas is technically feasible.

Object Rathke cleft cysts (RCCs) are benign lesions that can be diagnosed as an incidental finding associated with headaches, pituitary dysfunction, or vision deterioration. Typically, they occur in a sellar or suprasellar location. The aim of this study was to review the clinical presentation and outcomes associated with endoscopic endonasal resection of these lesions. Methods The authors retrospectively reviewed a series of 35 patients with a diagnosis of RCC after endoscopic endonasal resection at the University of Pittsburgh between January 1998 and July 2008. Results All 35 patients underwent a purely endoscopic endonasal approach (EEA). The average patient age was 34 years (range 12–67 years), and the average follow-up was 19 months (range 1–60 months). Clinical follow-up data were available for 32 patients, and radiographic follow-up data were accessible for 33 patients. All of the patients underwent complete removal of the cyst contents, and according to radiography studies 2 patients had a recurrence, neither of which required reoperation. The mean cyst volume was 1052.7 mm3 (range 114–6044 mm3). Headache was a presenting symptom in 26 (81.2%) of 32 patients, with 25 (96.1%) of 26 having postoperative improvement in their headaches. Fifteen (57.7%) of the 26 patients had complete pain resolution, and 10 (38.5%) had a > 50% reduction in their pain scores. Six (18.8%) of 32 patients initially presented with pituitary dysfunction, although 2 (33.3%) had postoperative improvement. Three (9.4%) of 32 patients had temporary pituitary dysfunction postoperatively, although there was no permanent pituitary dysfunction. Neither were there any intraoperative complications, postoperative CSF leaks, or new neurological deficits. The average hospital stay was 1.8 days (range 1–5 days). Conclusions The EEA is a safe and effective approach in the treatment of RCCs. None of the patients in this study experienced any worsening of their preoperative symptoms or pituitary function, and 96% of the patients who had presented with headache experienced complete or significant pain relief following treatment.

Spinal extradural cysts do not normally present as a visible paraspinal mass or cause compression of the abdominal organs. The authors describe the case of a 9-month-old boy with multiple spinal extradural cysts. The largest of these cysts was along the right L-2 nerve root with significant extraspinal extension resulting in a visible slow-growing swelling in the right paraspinal region and radiological evidence of compression of the right kidney with hydronephrosis. Another large cyst along the left T-12 root caused radiologically evident compression of the left kidney but to a lesser degree. The patient also had monoparesis of the left lower limb and phenotypic features of Noonan syndrome. The authors performed marsupialization of the cysts, as well as repair of the fistula between the subarachnoid space and the cyst on the right side along the L-2 root and on the left side along the T-12 root. At 1-year follow-up, there was no paraspinal mass and the lower limbs exhibited normal power. Magnetic resonance imaging confirmed marked reduction in the size of the cysts and relief of the renal compression. To the authors' knowledge, their patient is the youngest reported in literature to have a spinal extradural cyst and also the first with the cyst presenting as a paraspinal mass.

We report a case of a 40-year-old woman with synovial sarcoma who presented with neural symptoms in the medial aspect of the right foot and ankle. The radiographic appearance of the foot and ankle was unremarkable, but magnetic resonance imaging showed a relatively well-defined enhancing lesion in the plantar soft tissues extending from the master knot of Henry to the posterior tibialis tendon. After orthopedic oncologic evaluation and workup, the patient was ultimately treated with a transtibial amputation, and no evidence of recurrence or metastatic disease was seen at 6-month follow-up.
