“…In particular, limited to clinical signi cant hemorrhage, there are eight reported case in literature (Table 1). 22,[28][29][30][31][32][33] CK = CyberKnife, FS = facial schwannoma, GK = Gamma Knife, JFS = jugular foramen schwannoma, NR = not reported, SRS = stereotactic radiosurgery, VS = vestibular schwannoma * Hemorrhage occurred 3 days after the rst fraction, and 7 Gy had been irradiated to tumor. Some mechanism could be assumed from previous studies.…”

“…The previously reported post-SRS cases were managed surgically in six cases and conservatively in two other cases, largely ending up in a good recovery (Table 1). 22,[28][29][30][31][32][33] Consent for publication: Written informed consent for the publication of clinical details and images was obtained from the patient.…”

“…In particular, limited to clinically significant hemorrhage, there are eight reported cases in literature [ Table 1 ]. [ 5 , 9 , 11 , 13 , 16 , 20 , 31 ] A few patients developed symptomatic hemorrhage within 1 month after SRS, while others developed it several months or years later. Some mechanisms could be assumed from previous studies.…”

Background: Clinically significant intratumoral hemorrhage is a rare complication of stereotactic radiosurgery (SRS) for benign tumors. Case Description: Here, we present the case of a 64-year-old man who underwent SRS for a relatively large dumbbell-shaped left jugular foramen schwannoma (JFS) and thereafter developed intratumoral hemorrhage. On post-SRS day 3, he developed lower cranial nerve palsies with radiographically evident tumor expansion. His neurological conditions had gradually improved thereafter; however, he suddenly developed headache, dizziness, and mild hearing deterioration at 7 months due to intratumoral hemorrhage. We managed the patient conservatively, and eventually, his symptoms improved except for slight ataxia and hearing deterioration. Follow-up images at 4 years from SRS demonstrated significant tumor shrinkage. This is the first report describing intratumoral hemorrhage after SRS for JFS. Conclusion: Transient expansion of the tumor and subsequent venous stasis around the tumor may have played a role in the hemorrhage. Intratumoral hemorrhage should be considered as a rare, but potential complication of SRS for JFSs.

“…In particular, limited to clinical signi cant hemorrhage, there are eight reported case in literature (Table 1). 22,[28][29][30][31][32][33] Some mechanism could be assumed from previous studies. First, radiation induces microhemorrhage as well as other estimated factors, leading to necrotic expansion and rarely massive hemorrhage.…”

Background: Clinically significant intratumoral hemorrhage is an extremely rare complication of stereotactic radiosurgery (SRS) for benign tumors.Case Presentation:Here, we present the case of a 64-year-old man who underwent SRS for a relatively large dumbbell-shaped left jugular foramen schwannoma and thereafter developed intratumoral hemorrhage. On post-SRS day 3, he developed lower cranial nerve palsies with radiographically evident tumor expansion.

Intratumoral hemorrhage should be considered as a rare but potential complication of SRS for jugular foramen schwannomas.

Schwannomas are benign tumors that arise from Schwann cells and account for approximately 5% of all benign soft tissue tumors, are characterized by slow growth (1–2 mm per year) and are clinically asymptomatic for a long time.Material and methods. A review of literary sources for 2000–2023 was carried out, sources from the Russian scientific electronic library eLIBRARY, RSCI databases, and PubMed were used. A clinical case of patient with geniculate ganglion schwannoma is presented.Results. Schwannomas can occur at any age, no gender specific characteristics have been identified, the incidence most often occurs between the third and sixth decades, and there is an association with genetic disorders, in particular with neurofibromatosis. The dominant diagnostic methods remain MRI and MSCT of the brain.Conclusion. The presented clinical case demonstrates a long-term, asymptomatic course of geniculate ganglion schwannoma with intracranial spread. The surgical treatment contributed to improving the patient’s quality of life.
