This condition commonly affects immunocompromised individuals and the elderly, particularly those with a history of diabetes mellitus. Diagnosis is challenging because of non-specific symptoms that lead to late detection and complications. This report discusses a case of SBO with multiple bilateral cranial nerve abnormalities and highlights the diagnostic and management challenges in high-risk individuals with subtle clinical signs. Case presentation: This report describes a 63-year-old patient with hypertension and diabetes who underwent surgical debridement of the left ear due to malignant otitis externa 4 months prior to presentation. The patient presented with significant dysarthria, dysphagia, ptosis of the left eye with double vision, and hearing impairment in the left ear. Examination revealed bilateral CN VI palsy, right CN VII palsy, left CN VIII palsy, and a right CN XII deficit. Initial tests were unremarkable, but a high Fungitell assay and a second review of the CT scan and MRI revealed a pathological process in the base of the skull involving bony structures and cranial nerves bilaterally, which helped diagnose SBO. The patient was subsequently discharged with oral voriconazole and continued his usual medications. The patient requested further management abroad, because he did not notice resolution of his symptoms. Surgical treatment was employed abroad to relieve his symptoms, as he recovered slowly. Conclusion: This case report underscores the importance of a multidisciplinary approach to address SBO. Collaboration between specialists in infectious diseases, otolaryngology, radiology, and neurology plays a pivotal role in achieving an accurate diagnosis and developing a tailored treatment plan. Although SBO may be infrequent, this case report highlights the need to maintain heightened clinical suspicion in high-risk individuals.展开更多

The patient presented with symptoms of ptosis, fixation of the right eyeball, and left abducens palsy, indicating disturbances of the right oculomotor and trochlear nerves and bilateral abducens nerves. Brain contrast-enhanced computed tomography (CT) revealed an ill-defined mass with abnormal enhancement around the sella turcica. Brain magnetic resonance imaging (MRI) disclosed that the mass involved the clivus, cavernous sinus, and petrous apex. On contrast-enhanced MRI with gadolinium-chelated contrast medium, the mass showed inhomogeneous intermediate enhancement. The diagnosis of metastatic HCC to the skull base was made on the basis of neurological findings and imaging studies including CT and MRI, without histological examinations. Further studies may provide insights into various methods for diagnosing HCC metastasizing to the craniospinal area.展开更多

On evaluation with CT and MRI scans, he was found to have pan sinusitis with erosions of the skull base in the floor of sphenoid near lateral recess. PET-CT showed evidence of increased metabolism. He was operated upon by functional endoscopic sinus surgery and debridement of lesion near skull base. The histopathological examination revealed evidence of inflammation with no granulomas or fungal elements or tubercle bacilli. No organisms were grown in microbiological cultures. He started on empirical antibiotics for 3 months and showed improvement. We are reporting this case due to rarity to skull base osteomyelitis.展开更多

Nevertheless, in malignant tumors those flaps are not always available because of nasal septum invasion. Minimally invasive pericranial flaps (PCF) are associated with minimal adverse effects and good cosmetic appearance. In spite of that, there are only a few reports of this reconstructive technic limited to short surgical series and radio-anatomical analysis. Clinical results of a surgical cohort are presented. Study Design: Cohort prospective study. Methods: Clinical data, including age, gender, stage, histopathological findings, rate of complications and appearance of PCF at fifth day and two months postoperative were recorded. Postoperative morbidities were recorded as wound abnormalities, nasosinusal, orbital and central nervous system complications. Chi-squared test was used to correlate qualitative variables and Student-t-test to correlated qualitative and quantitative variables. Items were considered statistically significant with a p value of less than 0.05 (confidence Interval of 95%). Results: Thirty patients (18 males and 12 females) were registered. Mean age was 51.5 years ± 23.0 and range between 20 and 71 years. Most common histologic subtypes were adenocarcinoma, epidermoid carcinoma and squamous cell carcinoma. Complete resection of the tumor was achieved in all patients including surgical margins. Length of the PCF varies between 9.9 cm and 13.9 cm with a mean of 11.8 cm. There was an association between length of the flaps and the covering structure with the nose apex relation. None patient experienced postoperative cerebrospinal fluid (CSF) leak, frontal sinusitis or other complications. Conclusions: Minimally invasive PCF constitute a good and inexpensive reconstructive option in patients with malignant anterior cranial base tumors in whose nasoseptal flap was not a feasible option.展开更多
