Bilateral Primary Adrenal B-Cell Lymphoma Diagnosed by Workup for Primary Adrenal Deficiency.

Primary adrenal lymphoma (PAL) often occurs bilaterally and is a rare malignancy of old age. Workup for primary adrenal insufficiency often unmasks this underlying grave pathology. In this article, we present a case of a 73-yearold patient who presented with features of primary adrenal insufficiency and renal colic. Diagnostic abdominal imaging revealed bilateral suprarenal masses as the cause of adrenal gland destruction and the patient's symptoms. FDG PET-CT scan and histopathology confirmed the diagnosis of mature bilateral B-cell primary adrenal lymphomas. Though the patient showed an excellent initial response to the first four chemotherapy cycles, a relapse resulted in metastatic disease. This article highlights the PAL's disease course, imaging features, and management dilemma due to Chemotherapy's side effects and a higher recurrence rate.

Hepatic Candidiasis in an Immunocompetent Patient: A Diagnostic Challenge.

Hepatic candidiasis is a manifestation of disseminated candidiasis, which typically presents in immunocompromised patients. Focal hepatic candidiasis in immunocompetent patients, however, is infrequent/extremely rare. We present the case of an immunocompetent female patient who presented with respiratory distress and right-sided pleural effusion. The pleural fluid tap did not grow anything, and a contrast-enhanced computed tomography (CT) scan revealed a right liver lobe subcapsular collection. CT-guided aspiration and culture resulted in Candida albicans growth. The patient responded to oral fluconazole, and a follow-up CT scan demonstrated resolution of the collection. Although hepatic candidiasis rarely occurs in immunocompetent patients, it should be included in the differential diagnosis of hepatic abscesses, as timely diagnosis and management are crucial in conferring a good prognosis.

Chorionic Bump: Radiologic Features and Pregnancy Outcomes.

Background Chorionic bump is a rare condition defined as a bulge or protrusion from the choriodecidual surface into the gestational sac. The limited literature on this infrequent entity suggests that the pregnancies with multiple chorionic bumps mostly result in fetal demise. Aims To review the available literature and the patients from our institute having sonographic findings of chorionic bump and making the sonographers and radiologists aware of this known cause of first-trimester pregnancy loss. Study design A retrospective review of the cases diagnosed at our institute during the last four years. Methods and materials Single-center institutional data for four years (January 2016-December 2019) was accessed using ICD codes. IRB approval was waived owing to the anonymized use of patient data. Results Six female patients diagnosed with chorionic bump were included, with a mean age of 29.83±12 years. The average gestational age at the time of diagnosis was 8.16±3 weeks. The most common sonographic findings were a protrusion from the chorionic wall into the gestational sac cavity, having a central hypoechoic region with peripheral hyperechoic rim (isoechoic to the chorion) and having no vascularity (n=5), and the less common finding was a hyperechoic protrusion with no vascularity (n=1). n=5 had a single lesion, and n=1 had two lesions. The average diameter of the lesion in the largest dimension was 18±11 mm. n=3 pregnancies resulted in a first-trimester miscarriage, and n=3 pregnancies delivered healthy babies at term.  Conclusions A chorionic bump significantly increases the risk of a first-trimester miscarriage.

New cerebrosides from a marine sponge Haliclona (Reniera) sp.

A chemical investigation of the MeOH extract of a marine sponge Haliclona (Reniera) sp., collected off the coast of Ulleung Island, Korea, led to the isolation of thirteen new cerebrosides (1--3, 5--14), along with a known analogue (4). Their structures were elucidated on the basis of 1D and 2D NMR spectroscopy, MS spectrometry, and chemical method. The major new features of these glucocerebrosides are C15 and C19 acyl chains, long (C24-C28) acyl chains, or the S-configuration of the acyl chains. It is noteworthy that both R- and S-configurations of the acyl chains were observed in the same specimen.
