Esophageal Perforation Presenting Initially as Multiple Brain Abscesses Secondary to Streptococcus intermedius.

Brain abscess is a life-threatening infection that can occur secondary to contiguous or hematogenous spread. Several underlying conditions can lead to brain abscesses, such as dental infection, otitis media, sinusitis, and immunosuppression. Esophageal perforation leading to brain abscesses is extremely rare. We report a rare case of a 32-year-old man who presented to the emergency department with progressive headaches and upper-extremity weakness. Upon further evaluation, computed tomography (CT) revealed multiple brain abscesses secondary to Streptococcus intermedius infection. The patient eventually underwent esophagogastroduodenoscopy (EGD), which showed a perforation in the middle third of the esophagus. This case highlights the importance of considering esophageal perforation as a predisposing condition for brain abscesses.

Recurrent Cushing Syndrome From Metastatic Adrenocortical Carcinoma With Fumarate Hydratase Allelic Variant.

Background: Adrenal Cushing syndrome (CS) is usually benign in etiology; however, although rarely, it can be due to adrenocortical carcinoma (ACC); in which case, diagnosis and management are quite complicated. Case Report: A 34-year-old woman presented with worsening confusion, weight gain, new-onset diabetes, and hypertension. Her history was significant for a 7.4-cm left adrenal mass and CS, which were treated with left adrenalectomy 2 years ago. She received hydrocortisone replacement therapy after the surgery, which was discontinued on admission when evaluation showed hypokalemia, hypercortisolemia, and undetectable adrenocorticotropic hormone. Subsequent testing included 1-mg and 8-mg dexamethasone suppression tests, which did not suppress cortisol; late-night salivary cortisol measurement, which yielded a very high salivary cortisol level; and 24-hour urinary cortisol measurement. The level of 11-deoxycortisol was elevated. A computed tomography scan revealed multiple hepatic lesions, which were fluorodeoxyglucose avid, and a biopsy confirmed metastatic ACC. She received treatment with mitotane, metyrapone (later changed to mifepristone), doxorubicin, cisplatin, and etoposide. Over 8 weeks, mitotane levels became therapeutic at 20 mcg/mL, the hepatic masses decreased in size, and she transitioned to adrenal insufficiency and improved glycemic control. Next-generation sequencing of liver biopsy and germline testing revealed a frameshift loss-of-function allelic variant in the FH gene that encodes the protein fumarate hydratase. Discussion: We report a case of recurrent CS due to metastatic ACC in a patient with a previously resected adrenal adenoma and FH allelic variant. Conclusion: Metastatic ACC presenting with severe CS presents a diagnostic and management challenge where combination therapy guided by a multidisciplinary team is essential. FH allelic variant may contribute to ACC progression.
