Retroperitoneal #Teratoma


Case Overview

Case Description:

79 M presents to Cath Lab following traumatic encounter with a punching bag. Pt stated they kicked punching bag and felt a "tearing sensation" in their back. Pt noted to be severely intoxicated upon arrival and in extremely good spirits. CT showed a growing hematoma posterior to the left psoas muscle (orange arrows denote border) that was displacing peritoneal structures anteriorly and medially. Iliac and femoral vessels were also noted to be displaced, particularly the left common iliac which had a 180-degree bend. Access was made to the left common femoral with a 5F sheath. Following a difficult access, a 5F KMP 65 cm catheter was advanced to the left deep circumflex artery where diffuse bleeding was observed. An ultrafoam contrast slurry of approximately 90 cc's was introduced into the vessel to embolize it. Final angio shows significantly diminished flow. The inferior mesenteric artery was later attempted, but cannulation was impossible from the LFA approach and was abandoned. A SOS Omni flush catheter was advanced to the abdominal aorta and angiogram showed no more appreciable bleeding. Patient transferred to CT for retroperitoneal drain placement and is now in MCU step-down for observation.

Similar Cases

A 28-year-old male presents with a three-month history of a chronic cough and weight loss. Upon further discussion, he mentions a painless lump in his left testicle. A firm mass is felt in the left testis on examination. A chest X-ray reveals the pulmonary lesions seen here and a scrotal ultrasound confirms the presence of a heterogeneous tumor. Blood tests demonstrate highly elevated beta-hCG, slightly elevated lactate dehydrogenase (LDH), and normal alpha-fetoprotein (AFP) levels. Which testicular malignancy does this patient most likely have?

62yom, more than 8mo noticing weight loss, abdominal mass increasing in size, occasionally causing extrinsic intestinal obstruction. Previous US-directed biopsy only reports adipose and fibroid tissue, ascitic liquid with no malignant cells. Blood tests normal including tumor markers, just anemic. No other symptoms. Masses were not attached closely to anything in the retroperitoneum. Pending path.

Image description: Axial abdominal radiograph shows a cluster of dysmorphic calcifications in the left lower pelvis. Axial contrast-enhanced CT demonstrates a left ovarian mass containing macroscopic fat and calcified components.

Teaching point: Mature ovarian teratomas are composed of elements from multiple germ layers and commonly contain macroscopic fat and calcification. Fat density within an ovarian mass, especially when combined with coarse or tooth-like calcifications, strongly favors this diagnosis. In pediatric and adolescent patients, the mass effect of a teratoma increases susceptibility to adnexal twisting.

A 52-year-old man presented with a 20-minute history of chest pain radiating to the left shoulder and neck, associated with dyspnea and diaphoresis. He had a history of hypertension, long-term smoking, and a sedentary lifestyle. On physical examination, bibasilar crackles were noted on lung auscultation. An electrocardiogram (ECG) was performed in the primary care setting, and the patient was promptly referred to the emergency department.

A 28-year-old woman presented with a 3-day history of intense pruritus over the lower back. She reported no recent travel or exposure to new environments. She cares for a small kennel with approximately eight dogs rescued from the streets. Physical examination revealed multiple small vesicles, some clustered and others scattered, predominantly involving the lumbar region and the left gluteal area.

A 4-month-old male infant presented with skin lesions localized to the chin for the past 3 days. Physical examination revealed multiple small pustules with surrounding inflammatory signs on the chin, along with a few scattered papules on the chest.

Patient in late teens presenting after a collapse, no chest pain, no previous cardiac history, no history of sudden death in family, are there any features in this EKG that would warrant further work-up or is this just a pediatric EKG?
