A Spontaneous Renal Calyceal Rupture Mimicking Physiologic Changes of Pregnancy and Other Common Pathologies.

A spontaneous renal calyceal rupture in pregnancy is extremely rare and can be challenging to identify as its presentation can mimic other more common diagnoses, which can lead to a delay in management. Here, we describe an unusual case of renal calyceal rupture in a 24-year-old G2P0010 female with pregnancy at 26.5 weeks gestation age (WGA) who was admitted to the antepartum ward due to left flank pain and uterine contractions. A renal sonogram was performed, which revealed severe left hydronephrosis and the absence of the ipsilateral ureteral jet. Urinalysis was within normal limits, and her renal function was preserved. Laboratories were remarkable for elevated liver enzymes. Finally, an abdominopelvic MRI revealed the culprit, a calyceal rupture. Once the diagnosis was clear, a double J-stent was inserted using limited fluoroscopy with the goal of reducing intrarenal pressure and decreasing disease morbidity. The patient's symptoms significantly improved after double J-stent placement and resolved the following day. The patient further developed preeclampsia with severe features, which has previously been documented to occur in pregnant patients with renal tract ruptures. The diagnosis of a renal calyceal rupture in pregnancy is not straightforward, in part because of a lack of awareness of this pathology. Nevertheless, early identification can prevent unnecessary interventions and adverse outcomes. Its diagnosis can be made with MRI, and its management with ureteral stent placement shouldn't be delayed, and its association with preeclampsia should be further explored.

Small cell carcinoma of the uterine cervix: a case report and literature review.

Small cell carcinoma of the uterine cervix is a rare and aggressive extra-pulmonary variant of small cell tumors. This carcinoma of the cervix comprises less than 5% of all cervical carcinomas and is know to be highly undifferentiated. It is associated with a poor prognosis and characterized by premature distant nodal involvement. The survival rate at all stages ranges from 17% to 67%. We describe the case of a 41 year old female patient with a rare, and aggressive, clinical stage IB1 small cell neuroendocrine carcinoma of the cervix. The goal of this case report is to describe this rare pathology and contribute information to the scant available data.
