Facial nerve paresis as the presenting symptom of leukemia

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.

Neoplastic nerve lesions

Though metastasis and malignant infiltration of the peripheral nervous system is relatively rare, physicians should have a familiarity with their presentations to allow for prompt diagnosis and initiation of treatment. This article will review the clinical presentations, diagnostic evaluation, and treatment of neoplastic involvement of the cranial nerves, nerve roots, peripheral nerves, and muscle. Due to the proximity of the neural structure traversing the skull base, metastasis to this region results in distinctive syndromes, most often associated with breast, lung, and prostate cancer. Metastatic involvement of the nerve roots is uncommon, apart from leptomeningeal carcinomatosis and bony metastasis with resultant nerve root damage, and is characterized by significant pain, weakness, and numbness of an extremity. Neoplasms may metastasize or infiltrate the brachial and lumbosacral plexuses resulting in progressive and painful sensory and motor deficits. Differentiating neoplastic involvement from radiation-induced injury is of paramount importance as it dictates treatment and prognosis. Neurolymphomatosis, due to malignant lymphocytic infiltration of the cranial nerves, nerve roots, plexuses, and peripheral nerves, deserves special attention given its myriad presentations, often mimicking acquired demyelinating neuropathies.

Brachial plexus chloroma as a presenting feature of relapse in a child with KMT2A-rearranged acute lymphoblastic leukemia, a case report

Approximately 30–40% of relapses in pediatric acute lymphoblastic leukemia (ALL) are extra-medullary. KMT2A gene rearrangements are common in patients with infantile ALL. Chloromas are rare tumors composed of collections of acute leukemic cells that typically involve the bone or skin. Exceptionally uncommon, chloromas invade the peripheral nervous system, a phenomenon termed “neuroleukemiosis.” We describe A 6-year-old girl with a history of pre-B ALL with CNS involvement and KMT2A rearrangement diagnosed initially at 4 months of age. During continuation therapy she developed a scalp mass that was confirmed to be a leukemic relapse. She underwent re-induction chemotherapy followed by blinatumomab with subsequent remission and proceeded to allogeneic hematopoietic cell transplant (HCT). Three years following HCT, she presented with brachial plexus palsy and was found to have a lymphoblastic chloroma invading the brachial plexus. Review of existing literature shows relapse in pediatric ALL patients presenting as brachial plexus chloroma has only been documented once before. It has long been suggested that KMT2A gene rearrangements play a role in development of chloromas in patients with AML, however it is still unclear what role KMT2A has in ALL. Here we report a rare case of ALL relapse that presented as a left arm palsy secondary to a leukemic chloroma invading the brachial plexus and aim to explore the potential role of KMT2A in the formation of ALL chloromas.

Primary Presentation of Pediatric Hematopoietic Malignancy in the Temporal Bone: Case Report and Review of the Literature

Malignancy of hematopoietic origin comprises a large portion of all pediatric malignancies; however, it is uncommon for patients with this condition to present only with symptoms related to temporal bone involvement. Here, we report a case of Burkitt Lymphoma of the temporal bone in an 8-year-old patient who initially presented with symptoms of acute otitis media. Additionally, we review the current literature on pediatric hematopoietic malignancy with primary temporal bone involvement and discuss the clinical presentation, management, and outcomes of these rare cases.

Bilateral Facial Paralysis and Deafness in a Child Treated for Acute Lymphoblastic Leukemia

Involvement of the ear and temporal bone in acute leukemias are uncommon. We report a case of atypical mastoiditis with bilateral facial paralysis in a child diagnosed with Acute Lymphoblastic Leukemia (ALL). A 20-month-old male child was diagnosed with ALL and developed otorrhea unresponsive to antimicrobial treatment during the first week of chemotherapy followed by hearing loss, loss of balance, and bilateral facial paralysis. A CT scan of the mastoids showed cortical erosion of the temporal bone and presence of soft tissue contents filling the mastoid cells and external auditory canal bilaterally. Mastoidectomy was performed to collect material for analysis. Histopathologic examination of the material revealed an active chronic inflammatory process, with a moderate amount of plasma cells. Chemotherapy was reintroduced 3 weeks after the surgical procedure, and progressive improvement of otorrhea and imbalance was noted. Grade III House-Brackmann peripheral facial paralysis persisted on 6-month follow-up, and the patient is in rehabilitation program.

Plexus and peripheral nerve metastasis

Cancer in the form of solid tumors, leukemia, and lymphoma can infiltrate and metastasize to the peripheral nervous system, including the cranial nerves, nerve roots, cervical, brachial and lumbosacral plexuses, and, rarely, the peripheral nerves. This review discusses the presentation, diagnostic evaluation, and treatment options for metastatic lesions to these components of the peripheral nervous system and is organized based on the anatomic distribution. As skull base metastases (also discussed in Chapter 14) result in cranial neuropathies, these will be covered in detail, as well as cancers that directly infiltrate the cranial nerves. Particular emphasis is placed on the clinical, imaging, and electrodiagnostic features that differentiate neoplastic plexopathies from radiation-induced plexopathies. Neurolymphomatosis, in which malignant lymphocytes invade the cranial nerves, nerve roots, brachial and lumbosacral plexuses, and peripheral nerves, is a rare manifestation of lymphoma and leukemia. Diagnoses of neurolymphomatosis are often missed or delayed given its varied presentations, resulting in poorer outcomes. Thus this disease will also be discussed in depth.

Bilateral Facial Nerve Palsy in Acute B Cell Lymphoblastic Leukemia: A Case Report and Review of the Literature

Acute lymphoblastic leukemia (ALL) is a haematological malignancy that can involve the central nervous system (CNS). Less than 10 % of patients with ALL have CNS involvement at presentation. The cranial nerve most commonly affected is cranial nerve VII although bilateral involvement is rare. Management and outcomes of these patients are not well understood. Moreover bilateral Bells palsy as a presenting symptom of ALL is extremely uncommon. We report a very unusual presentation of ALL with bilateral facial nerve palsy, and discuss the management strategies and outcomes for patients with ALL that present with cranial nerve palsies.

Facial palsy as an unusual presenting symptom associated with acute myeloid leukemia

Extramedullary infiltration is common in acute myeloid leukemia (AML) patients. Although AML can cause neurological symptoms, especially when associated with extramedullary infiltration, a presenting manifestation of facial palsy is rare. We report on a 1-year-old boy who developed right facial palsy. Detailed examination led to a diagnosis of AML (French-American-British classification M1). Magnetic resonance imaging enhanced with gadolinium-diethylenetriamine penta-acetic acid showed abnormal enhancement of the right facial nerve, which disappeared after chemotherapy. AML should be considered as a differential diagnosis of facial palsy. Enhanced magnetic resonance imaging may be useful for diagnosing facial palsy associated with AML and for evaluating treatment outcome.

Orbital apex tumour caused by chronic lymphocytic leukaemia: an unlikely suspect

An 88-year-old woman with a background of chronic lymphocytic leukaemia (CLL) and presented with unilateral ptosis and dull facial pains for 1 month. Examination revealed a complete right-sided ptosis and pupillary dilation. Vision in her right eye was limited to light perception. She had total external ophthalmoplegia. Her corneal reflex was not present in her right eye and she had lost sensation on the right side of her forehead. MRI revealed abnormal enhancement in the right orbital apex extending posteriorly to the sphenoid sinus. The mass invaded the superior orbital fissure, optic canal and cavernous sinus. The lumbar puncture was normal. Owing to the proximity of the mass to the cavernous sinus, it was deemed that surgical excision of the tumour was unsafe; however, it was amenable to biopsy. Histology of the biopsies was consistent with CLL. The patient declined to undergo single high-dose radiotherapy followed by dexamethasone.

Clinicopathological characteristics of extramedullary acute megakaryoblastic leukemia (AMKL): report of a case with initial mastoid presentation and review of literature to compare extramedullary AMKL and non-AMKL cases

Extramedullary acute megakaryoblastic leukemia (AMKL) is a rare neoplasm with a varied clinical presentation. AMKL with initial mastoid presentation has never been reported. The extreme rarity of mastoid AMKL, together with the tendency of extramedullary AMKL to mimic other small blue cell tumors, can create a diagnostic challenge. We report a case of AMKL that initially presented as a mastoid lesion and provide a comprehensive review and analysis that compares the characteristics of extramedullary AMKL and nonmegakaryoblastic acute myeloid leukemia (AML) in reported pediatric cases over the past 30 years. We found that patients with extramedullary AMKL were not only younger than patients without megakaryocytic differentiation but were also limited to those ≤ 2 years of age. In addition, girls predominated in both AMKL and AML MLL(+) groups compared with other types of AML (P  =  0.0366 and P  =  0.0082). Furthermore, we found that extramedullary AMKL was more likely to involve bone than AML MLL(+) (P < 0.0001) or other types of AML (P  =  0.0002). These findings suggest that extramedullary AMKL should be considered in the differential diagnosis of SBCT in children, especially in patients with mastoid or other bony lesions, those ≤ 2 years of age, and female patients.

Incidence of non-infectious ‘acute mastoiditis’ in children

Objective:

The temporal bone may be the first involved site in cases of systemic disease, and may even present with acute, mastoiditis-like symptomatology. This study aimed to evaluate the incidence of such non-infectious ‘acute mastoiditis’ in children.

Materials and methods:

Retrospective chart review of 73 children admitted to a tertiary referral centre for acute mastoiditis.

Results:

In 71 cases (97.3 per cent), an infectious basis was identified. In the majority of cases (33 of 73; 45 per cent), the responsible bacteria was Streptococcus pneumoniae. However, histopathological studies revealed a non-infectious underlying disease (myelocytic leukaemia or Langerhans' cell histiocytosis) in two atypical cases (2.7 per cent).

Conclusion:

‘Acute mastoiditis’ of non-infectious aetiology is a rare but real threat for children, and a challenging diagnosis for otologists. A non-infectious basis should be suspected in every atypical, persistent or recurrent case of acute mastoiditis.

Granulocytic sarcoma presenting as atypical mastoiditis with facial paralysis: description of a case

We describe a case of temporal granulocytic sarcoma in a 26-year-old patient after apparent molecular remission of an acute myeloid leukaemia. He complained of otodynia with hearing loss and facial paralysis on the right side. He was treated with chemotherapy and self-transplant haematopoietic stem cells. He was cured clinically, molecular remission of the haematological processes was achieved, and he remained asymptomatic for three years. Facial paralysis and hearing loss associated with temporal GS should be treated with chemotherapy. Aggressive surgery may complicate the clinical course of the disease and it should be avoided.

Temporal bone myeloid sarcoma

Myeloid sarcoma is a rare condition that's caused by the aggregation of immature myeloid cells in leukemic patients. Myeloid sarcoma occurring in the temporal bone more frequently involves the mastoid bone than is the case for metastatic lesions arising from non-systemic malignancies. The disease is difficult to diagnose when it presents with symptoms that mimic otomastoiditis. However, an early diagnosis is important in order to achieve complete remission of the disease. Magnetic resonance imaging of the temporal bone is useful for making the diagnosis of myeloid sarcoma, and especially to evaluate the extent of disease. High-dose radio- or chemotherapies are the first-line approaches and possibly the only approaches to achieve complete remission and to cure the disease. With the aim of improving our understanding of myeloid sarcoma in the temporal bone, the present report describes our experience with 5 such cases and we compare the clinical features of these 5 patients with those clinical features of patients who have metastatic lesions.

Acute sciatica: an unusual presentation of extramedullary relapse of acute lymphoblastic leukemia

A 10-year-old boy who had been treated for acute lymphoblastic leukemia presented with persistent numbness of the left big toe and progressive pain of the ipsilateral lower leg. He had received allogeneic bone marrow transplantation 3 months after a testicular relapse. He was in hematologic remission at admission but as progressive swelling of his left leg continued, bone marrow relapse developed. A muscle biopsy revealed leukemic infiltrates in the surrounding muscles of the left sciatic nerve, and swelling of the nerve was found on a magnetic resonance imaging scan. His symptoms/signs subsided soon after reinduction chemotherapy. Unfortunately, he didn't survive because of a fungal sepsis that developed during the neutropenic state. This case represents a rare neurologic complication of what is currently an uncommon presentation for relapse of acute lymphoblastic leukemia, with acute sciatica and without coexisting epidural or leptomeningeal leukemia.

Facial paralysis as a presenting symptom of leukemia

Facial paralysis may occur as a complication of central nervous system leukemias in children, but it is rarely a presenting symptom. This report describes an 8-month-old child who presented with peripheral facial palsy, failure to thrive, anemia, and otitis media. Antibiotic and steroid treatment led to an improvement in the clinical condition, but not the paralysis. At readmission 3 weeks later, physical examination revealed bluish, firm, palpable masses on the scalp and facial areas, and laboratory and imaging studies confirmed the diagnosis of acute myeloid leukemia. This case should alert physicians to consider hematologic malignancies in children with facial paralysis.

Acute myeloid leukemia presenting as spinal cord compression

We report the findings of a 10-year-old boy who presented to a pediatric emergency department with symptoms of spinal cord compression. Radiological imaging demonstrated multiple soft tissue masses in the head and spine. The surgical pathology showed that the masses were comprised of myeloid leukemia cells. These findings were consistent with those observed on bone marrow aspiration. The characteristics and management of extramedullary leukemia are discussed.

An alarming sign for serious diseases in children: bilateral facial paralysis

Facial paralysis in children is most often idiopathic, and isolated facial nerve palsy resulting from leukemic infiltration is a rare occurrence. We report a 13-year-old male with acute lymphoblastic leukemia presenting with bilateral facial palsy, who was previously diagnosed with idiopathic facial palsy and treated with steroids. This rare presentation of acute lymphoblastic leukemia should be kept in mind as a diagnostic possibility in a patient with bilateral facial nerve paralysis.

Recurrent attacks of facial nerve palsy as the presenting sign of leukemic relapse

OBJECTIVE

To present an unusual case of recurrent facial palsy resulting from acute leukemic infiltration of the parotid gland.

STUDY DESIGN

Case report.

METHODS

An 11-year-old boy who had been treated for acute lymphoblastic leukemia (ALL) from 3 to 6 years of age presented with intermittent left facial nerve palsy with concurrent ipsilateral parotid fullness. The initial findings at diagnosis and workup are presented, and the disease progression and resolution with therapy are documented.

RESULTS

The patient had been off therapy when this finding developed. A workup for central and viral etiologies for the facial palsy was unrevealing. Biopsy of the parotid gland demonstrated a lymphoblastic leukemic infiltrate. The patient was placed on a chemotherapy protocol for relapsed leukemia, resulting in complete resolution of the facial palsy.

CONCLUSION

Isolated facial nerve dysfunction, albeit rare, has been documented as a sign of central nervous system involvement in leukemia, but until now this presentation has not been described in the setting of leukemic relapse presenting with acute infiltration of the parotid gland.

Head and Neck Granulocytic Sarcoma with Acute Myeloid Leukemia: Three Rare Cases

We conducted a retrospective review of pathology files and hospital records and identified three unusual presentations of granulocytic sarcoma associated with acute myeloid leukemia (AML) of the head and neck. At least one mass was observed on the skin of all three patients. A 17-year-old boy had masses in each temporal region that were accompanied by bilateral facial paralysis. He was administered chemotherapy and radiotherapy, but he died of infection secondary to a second relapse 29 months after the initial diagnosis. A 17-year-old girl had a tumor in the right parotid area. She received chemotherapy, but she died of infection and bleeding 2 months after the initial diagnosis. A 33-year-old man had numerous tumors widely disseminated over his skin. He received chemotherapy and was in remission 12 months after the initial diagnosis, but he eventually relapsed and died. Granulocytic sarcoma can be localized in unexpected regions, including the head and neck. This tumor is very often misdiagnosed as a malignant lymphoma, which leads to delayed treatment and a poor outcome. Therefore, clinical and histopathologic findings should be evaluated before any diagnosis of malignant lymphoma is pronounced. Immunohistochemical stains should also be performed on patients with suspected granulocytic sarcoma, and aggressive chemotherapy or immunotherapy should be administered. We believe that high-dose chemotherapy can improve survival rates in granulocytic sarcoma associated with AML.

Otological manifestations of acute leukaemia: report of two cases and review of literature

Otological manifestations exceptionally reveal acute leukaemia, whereas leukaemic infiltration of any tissue is frequent at postmortem examination. We present two cases of acute myeloblastic leukaemia revealed by a loss of hearing due to a middle-ear leukaemic infiltration. The characteristics of such a clinical and radiological finding are emphasized. It is suggested that middle and inner ear can be a 'sanctuary' localization, which might sometimes require radiation therapy to achieve durable and complete remission.

Chloroma of the masseteric muscle

Chloroma (leukemic infiltrate or granulocytic sarcoma) is a localized extramedullary mass of immature granulocytic cells. They are uncommon tumors that usually occur in patients with leukemia, mostly of the myeloid type. Involvement in the head and neck region is rare. Granulocytic sarcomas of the face, maxilla, paranasal sinuses, temporal bone, and pharynx have all been documented in the past. We present the first reported case of a granulocytic sarcoma involving the masseteric muscle in an 8-month-old white male diagnosed with acute myeloid leukemia (AML). The lesion resolved with chemotherapy but the patient subsequently died. This case reaffirms the importance of including chloroma in the differential diagnosis of lesions in patients with AML and the prognostic value they hold.

Facial nerve paralysis in acute otomastoiditis as presenting symptom of FAB M2, T8;21 leukemic relapse. Case report and review of the literature

Granulocytic sarcoma (chloroma) is a rare solid, extramedullary tumour composed of immature granulocytes, occurring during granulocytic leukemia. Leukemic involvement of the temporal bone is not uncommon and may present in a variety of ways. Symptomatic facial nerve paralysis is one of these. The authors report a case of facial nerve paralysis as the presenting symptom of leukemic relapse in a 16-year-old white male, affected by acute myelogenous leukemia FAB M2, karyotype 46xy, T8;21.

Facial Nerve Palsy as an Early Manifestation of Relapse in T-Cell Acute Lymphoblastic Leukemia

We describe a 14-year-old girl with T-cell acute lymphoblastic leukemia (ALL) who developed peripheral type facial palsy alternately on each side during remission. The cerebrospinal fluid examination and imaging studies of the brain including the temporal area failed to identify the etiology. Fully 10 weeks after the onset of the facial nerve palsy, she showed cytological findings of meningeal and bone marrow relapse. Review of the literature revealed that an isolated facial nerve palsy due to leukemic cell infiltration is a rare occurrence. Nonetheless one needs to keep in mind that it may represent the initial sign of a relapse in a patient with leukemia, particularly with T-cell ALL.

Megakaryoblastic leukemia presenting as a temporal bone granulocytic sarcoma. Case report

The unusual presentation of acute megakaryoblastic leukemia as a temporal bone granulocytic sarcoma in an infant without systemic manifestations of leukemia is reviewed. Leukemia should be considered in the differential diagnosis of skull and skull-based lesions since the appearance on neuroradiological imaging is not unique in this diagnosis. Surgical treatment, as in this case, is limited to obtaining tissue for diagnosis and draining the infection.
