Frontal sinus lymphoma presenting as progressive multiple cranial nerve palsy

A Scoping Review of Otologic Manifestations of Hematologic Malignancies

OBJECTIVE

To examine the otologic and neurotologic symptoms, physical examination findings, and imaging features secondary to hematologic malignancies.

METHODS

Following Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines, databases, including PubMed, Scopus, and CINAHL, were searched for articles including patients with otologic manifestations of leukemia, lymphoma and multiple myeloma. Data collected included patient and study demographics, specific hematologic malignancy, timing and classification of otologic symptoms, physical examination findings, imaging features and methods of diagnosis. Pooled descriptive analysis was performed.

RESULTS

Two hundred seventy-two articles, of which 255 (93.8%) were case reports and 17 (6.2%) were case series, reporting on 553 patients were identified. Otologic manifestations were reported on 307 patients with leukemia, 204 patients with lymphoma and 42 patients with multiple myeloma. Hearing loss and unilateral facial palsy were the most common presenting symptoms for 111 reported subjects with leukemia (n = 46, 41.4%; n = 43, 38.7%) and 90 with lymphoma (n = 38, 42.2%; n = 39, 43.3%). Hearing loss and otalgia were the most common presenting symptoms for 21 subjects with multiple myeloma (n = 10, 47.6%; n = 6, 28.6%). Hearing loss and unilateral facial palsy were the most common otologic symptoms indicative of relapse in subjects with leukemia (n = 14, 43.8%) and lymphoma (n = 5, 50%).

CONCLUSION

Hearing loss, facial palsy, and otalgia might be the first indication of a new diagnosis or relapse of leukemia, lymphoma, or multiple myeloma. Clinicians should have a heightened level of suspicion of malignant etiologies of otologic symptoms in patients with current or medical histories of these malignancies.

Sinonasal Malignancies Involving the Frontal Sinus: A Mono-Institutional Experience of 84 Cases and Systematic Literature Review

Frontal sinus involvement by malignant tumors is a rare finding. Therefore, a systematic literature review along with a personal case series may contribute to defining more accurately the epidemiology, treatment options, and outcomes of these neoplasms. This is a retrospective review of patients affected by frontal sinus malignancies surgically treated in a tertiary-care referral center over a period of 20 years. Moreover, a systematic literature review of studies describing frontal sinus cancers from 2000 to date was performed according to PRISMA guidelines in order to analyze current evidence about the treatment and outcomes of such a rare disease. Our retrospective review was basedon 84 cases, treated with an exclusive endoscopic approach in 43 cases (51.2%), endoscopic approach with frontal osteoplastic flap in 6 cases (7.1%), and transfacial or transcranial approaches in 35 cases (41.7%). The five-year overall, disease-specific, disease-free, and recurrence-free survivals were 54.6%, 62.6%, 33.1%, and 59.1%, respectively. Age, dural involvement, type of surgical resection, and surgical margin status were significantly associated with the survival endpoints. In conclusion, the involvement of the frontal sinus is associated with a poor prognosis. Multidisciplinary management, including specific histology-driven treatments, represents the gold standard for improving outcomes and minimizing morbidity.

Pediatric Diffuse Large B-Cell Lymphoma of the Frontal Sinus: A Case Report

An 11-year-old male presented with right proptosis, bulbar conjunctivitis, and diplopia. Computerized tomography (CT) and magnetic resonance imaging revealed an enhancing mass involving the superio-medial orbit, ethmoids, frontal sinus, and anterior cranial fossa with skull base destruction. Diffuse large B-cell lymphoma was diagnosed via CT-guided biopsy. As a component of multidisciplinary care, the patient underwent frontal sinus cranialization, with orbital and skull base reconstruction. Trauma reconstructive principles guided recreation of orbital, frontal sinus, and anterior skull base anatomy. This rare primary location is undescribed in the pediatric literature.

Diffuse Large B-Cell Lymphoma of the Frontal Sinus Presenting as a Pott Puffy Tumor: Case Report

Objective Sinonasal non-Hodgkin lymphoma (NHL) is a very rare condition. NHL located specifically in the frontal sinus is even rarer with only 14 cases in the literature reported to date. A unique case of diffuse large B-cell lymphoma of the frontal sinus that presented first and was treated as suspected Pott puffy tumor is presented along with a review of the literature. Case Report A 69-year-old white man with a history of sinusitis and two recent endoscopic sinus surgeries presented with enlargement of his right forehead. Computed tomography and magnetic resonance images revealed a dense opacification of the frontal sinus bilaterally, thickening and enhancement of the dura mater behind the right frontal sinus, and local osteomyelitis-like lytic bone changes. A bifrontal craniotomy was performed. Radical exoneration of the frontal sinus, copious antibiotic-impregnated irrigation after culture swabs, and resection of presumed granulation tissue was performed. Culture swabs remained negative, but histopathology revealed diffuse large B-cell lymphoma. Subsequent chemotherapy was administered. Conclusion Sinonasal NHL is very rare but can occur in the frontal sinus and may present as a suspected Pott puffy tumor. A high clinical suspicion is necessary for early diagnosis and treatment.
