Frontal osteomyelitis post-COVID-19 associated mucormycosis

Rhino-orbito-cerebral mucormycosis (ROCM) is the most commonly noted form of mucormycosis, which is the most common secondary fungal infection following severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection. Osteomyelitis is one of the rare sequelae of ROCM, frontal osteomyelitis being the rarest. We present four patients of coronavirus disease 2019 (COVID-19)-associated mucormycosis, who presented with frontal bone osteomyelitis after being treated for ROCM surgically and medically. This is the first case series highlighting this complication in post–COVID-19 mucormycosis patients and needs utmost attention as it can be life-threatening and can cause extreme facial disfiguration. All four patients are alive with salvage of the affected globe and vision being preserved in one patient. If identified early, disfiguration of face and intracranial extension can be avoided.

Tumor Inflamatorio de Pott: reporte de un caso y revisión de la literatura / Pott's puffy tumor: a case report and review of the literature

INTRODUCCIÓN: El Tumor inflamatorio de Pott es una complicación rara de una patología frecuente, como son los cuadros infecciosos sinusales, cada vez más inusual por el uso extendido de antibióticos de amplio espectro, es más frecuente en la población adolescente por la neumatización similar al adulto. Se presenta como un aumento de volumen blando a nivel frontal con una osteomielitis del hueso frontal y un absceso subperióstico. MATERIALES Y MÉTODOS: En este trabajo, se presenta una revisión bibliográfica del tema y un caso de un paciente de 9 años, quien cursó con un cuadro infeccioso sinusal, que posterior desarrollo un aumento de volumen frontal, mostrando las imágenes perioperatorias e intraoperatorias. DISCUSIÓN Y CONCLUSIÓN: El absceso subperióstico secundario a la sinusitis, es una complicación rara. Sin embargo, se debe pensar en el diagnostico en pacientes de evolución tórpida y/o que presentan sintomatología neurológica, como convulsiones, se debe completar el estudio con neuroimagen contrastada.

INTRODUCTION: Pott's inflammatory tumor is a rare complication of a frequent pathology, such as sinus infections, increasingly unusual due to the use of broad-spectrum antibiotics, it is more frequent in the adolescent population due to pneumatization similar to that of adults. It presents as an increase in volume at a frontal level with osteomyelitis of the frontal bone and a subperiosteal abscess. ;MATERIAL AND METHODS: In this work, we present a bibliographic review and a case of a 9-year-old patient, who presented with an infectious sinus, which later developed an increase in frontal volume, the perioperative and intraoperative images are shown. DISCUSSION AND CONCLUSION: Subperiosteal abscess secondary to sinusitis is a rare complication. However, the diagnosis should be considered in patients with torpid evolution and / or who present neurological symptoms, such as seizures, the study must be completed with a contrast brain image.

The Unknown Cause of Pott's Puffy Tumor ­ Importance of Early Diagnose

Pott's puffy tumor (PPT) is characterized by swelling of the glabelar region and osteomyelitis of the frontal bone, owing to a subperiosteal pseudoinflammatory tumor responsible for the detachment of the pericranium from the outer table of the skull. Nowadays, the incidence of PPT is very low, so this entity is frequently underdiagnosed. The late treatment and identification of PPT are strongly associated with intracranial complications, which could jeopardize the life of the patient. In the literature, PPT is described as a complication of frontal head trauma or of chronic sinusitis. There are a few cases reported in patients with frontal insect bites or in recreational nasal drug users, such as cocaine or methamphetamines. In the present case report, the authors describe the case of a 40-year-old male who was submitted to a frontal sebaceous cyst surgery. In the postoperative period, he developed an infectious process compatible with PPT. After an extensive review of the literature, no similar cases were identified. Therefore, in the opinion of the authors, sebaceous cyst surgery should be included in the short list of risk factors for the development of PPT.

Pseudotumor inflamatorio de Pott: una complicación olvidada y peligrosa de la sinusitis / Pott's puffy pseudotumor: a forgotten and dangerous complication of sinusitis

Resumen El pseudotumor inflamatorio de Pott es una de las posibles complicaciones de la sinusitis. En la literatura existen pocos casos reportados de esta entidad, pero el presente artículo expone cuatro casos con el propósito de concientizar al grupo médico sobre la existencia de esta enfermedad y cómo su manejo temprano puede prevenir complicaciones severas.

Abstract Pott's puffy pseudotumor is one of the possible complications of sinusitis. The literature reports few cases related to this entity; however, this article presents a series of four cases to raise awareness among the medical group of the existence of this disease, and how timely management can prevent severe complications.

Tumoración de Pott: A propósito de un caso / Pott puffy tumor: Case report

Se analiza el caso de un niño con sinusitis frontal, con una forma de presentación poco habitual que, además, padecía una complicación intracraneal grave. Las complicaciones intracraneales de las sinusitis son raras en cerebrales y trombosis del seno cavernoso. Se hace hincapié en la importancia del diagnóstico precoz y de un tratamiento empírico inicial adecuado para evitar las posibles complicaciones. Asimismo, cabe enfatizar que una vez producidas estas, requieren un tratamiento médico-quirúrgico intensivo para su resolución.

We present the case of a child with frontal sinusitis, who also suffers from a severe intracranial disease. Although sinusitis intracranial issues are rare nowadays, they include a wide range of serious entities such as meningitis, brain abscesses and thrombosis of the cavernous sinus. We emphasize the importance of early diagnosis and an adequate initial empirical treatment to prevent possible complications. Once they are presented, an aggressive surgical medical treatment is required for its resolution.

A Case of Pott's Puffy Tumor from Recurrent Upper Eyelid Abscess

PURPOSE: To report a case of Pott's puffy tumor from a recurrent upper eyelid abscess. CASE SUMMARY: A 73-year-old male visited our clinic with recurrent upper eyelid abscess over the previous 3 months. The patient did not have any evidence of external injuries, systemic inflammations, or any other specific findings. The best corrected visual acuity was 0.9 in the right and 0.5 in the left eye with normal IOP. Enhanced CT revealed a focal low density mass (11.3 x 12.6 x 10 mm) with peripheral enhancement. An excisional biopsy was performed. Histopathologic examination revealed chronic inflammation and granulation tissue formation and the patient was diagnosed with Pott's puffy tumor. The patient experienced no discomfort after the excision biopsy. At the 14-month follow-up, there were no signs of recurrence. CONCLUSIONS: Although rare, Pott' puffy tumor should be considered in the differential diagnosis of upper eyelid mass.
