Vascular Lesion of Neck with Lymphatic Cyst of the Right Parapharyngeal Space

Background: Tentorial dural arteriovenous fistula (TDAVF) is a rare intracranial vascular shunt. A TDAVF can be supplied by the Artery of Wollschlaeger and Wollschlaeger (AWW). However, a limited number of cases of TDAVF fed by the AWW have been reported to date. Case Description: A 70-year-old woman complaining of the right motor weakness underwent magnetic resonance imaging. A vascular lesion beneath the cerebellar tentorium was incidentally found with chronic infarction of the left corona radiata. Angiographically, the vascular lesion was a TDAVF supplied by the bilateral posterior meningeal arteries. No other apparent feeders were detected. The TDAVF had a shunting point on the inferior surface of the cerebellar tentorium with venous retrograde flow (Borden type III, Cognard type III). To prevent vascular events, endovascular embolization was performed using n-butyl-2-cyanoacrylate. Following embolization of the shunting point, a residual shunt fed by the AWW was identified. The shunt supplied by the AWW was not observed preoperatively. Follow-up angiography performed 1 week later revealed spontaneous disappearance of the residual shunt. The patient was followed-up in our outpatient clinic, and no recurrence of the TDAVF was confirmed postoperatively. Conclusion: Detection of mild feeding from the AWW to a TDAVF can be elusive preoperatively. Following embolization of the main shunting point, residual shunting from the AWW can resolve spontaneously.

Spindle cell lipomas are usually located in the subcutaneous tissue of the back, shoulders, and neck. To our knowledge, the presence of such a tumor in the parapharyngeal space has not yet been described. We evaluated a 45-year-old man with a tender swelling of the right parotid area that had reached the submandibular area. Clinical examination and magnetic resonance imaging revealed the presence of a tumor that coated the parotid area laterally and extended into the center of the parapharyngeal space, thus causing a dislocation of the pharyngeal muscles and mucosa. We performed a total parotidectomy and submandibulectomy on the right side and extirpated the parapharyngeal tumor. We were able to spare the facial nerve, and no facial paralysis occurred. Histologic examination revealed an atypical lipomatous tumor with a remarkably large portion of spindles.

Tumors of the parapharyngeal space (PPS) are rare, most originate from salivary and neurogenic tissues, and most are benign. However, there are some rarer masses in the PPS, with just a few published reports in the literature worldwide, and we may not consider them in the differential diagnosis of PPS neoplasms. We report three cases of rare masses in the PPS: Warthin’s tumor, branchial cleft cyst, and carcinoma ex pleomorphic adenoma. The three patients were admitted to our department with complaints of painless swelling in the lower side of the right face or a long history of snoring; diagnoses were confirmed histopathologically. An endoscopy-assisted transoral approach was used that allowed wide visibility for safe resection and resulted in a short hospitalization time and good functional and cosmetic outcomes. All patients have been followed to the current time, and there have been no recurrences. The transoral endoscopy-assisted approach appears to be safe, effective, and less invasive for excision of masses in the PPS.

AbstractWyburn–Mason syndrome is a rare condition that is characterized by ipsilateral arteriovenous malformations affecting the eye, brain, and facial skin. A conjunctival vascular dilation can be a rare ocular presenting sign. We report a 6-year-old boy who attended the hospital because of the sudden appearance of a conjunctival vascular lesion in his right eye. Inspection of his facial skin showed a subtle discoloration along the right trigeminal nerve and a vascular structure of the conjunctiva. Fundoscopy showed dilated and tortuous retinal vessels. Brain magnetic resonance imaging (MRI) revealed a large arteriovenous malformation involving the thalamus and perimesencephalic area. Ophthalmologic and neuroradiologic findings were consistent with the diagnosis of Wyburn–Mason syndrome. The sudden emergence of a vascular malformation in the conjunctiva should alert the clinician to perform an ophthalmoscopy, and in our patient, this finding was the clue to diagnosis of Wyburn–Mason syndrome. Because of the association between retinal and intracranial arteriovenous malformations, an MRI of the brain is strongly recommended in all patients with ocular arteriovenous malformations.

✓ This 10-year-old child suffered a hemorrhage into the right parietal lobe, the result of a ruptured arteriovenous angioma. From birth, the boy had a venous angioma of the mucous membrane of the cheek, lower lip, and hypoglossal area on the right side. The coexistence of these two vascular defects is most unusual, and venous angioma in early life may suggest the presence of cerebral angioma.

Transtentorial Approach

A 57-year-old man presented with acute changes in mental status. Brain CT showed a high-density lesion at the pons. Brain MRA revealed a very slow-flow vascular lesion at the right aspect of the pons, about 3.9 ⋅ 3.0 ⋅ 3.0 cm3, compatible with a pontine cavernous malformation (CM). Gross-total removal was achieved. In this approach, a wider surgical corridor was obtained by opening the Meckel’s cave and cutting the tentorium. For a midline attack point on the pons, additional removal of the posterior clinoid process can meet the goal. In the authors’ opinion, this approach is safe and effective in selected ventrolateral pontine CMs.The video can be found here: https://youtu.be/moHqEkp5eCA.

ABSTRACT Langerhans cell histiocytosis (LCH) is a rare disease with unknown etiology involving abnormal proliferation of histiocytes. We hereby describe an LCH that has a rare location. A 4-year-old female patient was referred to our clinic with headache lasting for 2 months. Magnetic resonance imaging (MRI) showed an expansile mass on the level of basisphenoid extended to the right parapharyngeal space with dense contrast enhancement. The patient underwent endoscopic endonasal transsphenoidal surgery for biopsy of the mass. Immunohistochemical and pathological studies confirmed LCH diagnosis. This is the first case report of LCH extended to the parapharyngeal space in the current literature. How to cite this article Salimov A, Suslu AE, Ozer S, Yilmaz T, Bajin HIY.

A woman in her 60s presented with a recurrent lymph node metastasis from a papillary thyroid carcinoma in the right parapharyngeal space. She had already undergone total thyroidectomy, five resections for cervical lymph node metastases, and right carotid rebuilding. Surgical resection of the current metastasis was impossible. 131I-radioiodine therapy (RIT) with 3.7 GBq 131I was not effective; therefore, stereotactic radiation therapy (SRT) using a CyberKnife radiotherapy system was scheduled. The prescription dose was 21 Gy, and a dose covering 95% of the planning target volume (PTV) in three fractions was administered. The PTV was 4,790 mm3. Follow-up magnetic resonance imaging conducted 3 and 12 months after the SRT demonstrated a remarkable and gradual reduction of the recurrent lymph node metastasis in the right parapharyngeal space and no evidence of recurrence. For multidisciplinary therapy of unresectable and/or RIT unresponsive locoregional lymph node metastases and recurrences of DTC, SRT using the CyberKnife system should be considered.
