10 Possible Causes for CT Scan showing Adrenal Mass, Increased Basal Metabolic Rate, Retroperitoneal Hemorrhage

  • Pheochromocytoma

    If imaging with MRI or CT scans of the adrenal glands shows a mass in the gland (or outside it), surgery may be done.[] […] fat metabolism for energy (breaking down of fats for fuel) increases basal metabolic rate (burns more calories) increases thermogenesis (elevates body temperature) how you[] CT scan showed previously undiagnosed large right adrenal mass (5.9cm). The diagnosis of pheochromocytoma was confirmed after adrenalectomy.[]

  • Angiomyolipoma

    The follow-up 18F-FDG PET/CT scan showed a nearly complete resolution of the previously detected adrenal mass, with very low tracer uptake and a decrease in its functional[] Multiple hypermetabolic pulmonary metastases were also noted.[] Symptomatic presentation is most frequently with spontaneous retroperitoneal hemorrhage ; the risk of bleeding is proportional to the size of the lesion ( 4 cm diameter).[]

  • Renal Cell Carcinoma

    Computer tomography (CT) scan showed a solid right renal lesion, multiple liver metastases, florid chest, lymphadenopathy in left supraclavicular region and a right adrenal[] In addition, the patient had 2 hypermetabolic uterine leiomyomas.[] Spontaneous Retroperitoneal hemorrhage in pregnancy is a rare condition. Renal angiomyolipoma (RA) is the most common cause of this hemorrhage.[]

  • Adrenal Hemorrhage

    Abdominal CT scan ( Figures 2 and 3 ) showed a mass with spontaneous hyper-dense aspects in the hepato–renal space corresponding to the adrenal lodge.[] Imaging findings that may indicate underlying tumor include intralesional calcification, enhancement, and hypermetabolic activity on PET images.[] A computerized tomography scan of the abdomen with intravenous contrast demonstrated massive right-sided retroperitoneal hemorrhage.[]

  • Adrenocortical Carcinoma

    CT scan of the abdomen revealed a 35 mm left adrenal mass.[] No metastasis or size increase of the remaining adrenal glands were found suggesting that their hypermetabolic state could be attributed to mitotane treatment.[] We report an unusual case of a spontaneously ruptured adrenocortical carcinoma that initially presented as a critical massive retroperitoneal hemorrhage.[]

  • Adrenal Gland Metastasis

    (a) US scan shows a septated cystic mass of the right adrenal gland (arrows). (b) Contrast material-enhanced CT scan shows a lobulated cystic mass with calcified septa.[] The PET/CT revealed a nodular hypermetabolic focus located on the left adrenal gland, measuring 2.5 2.6 2.8 cm, and the maximum standardized uptake value was 3.9 ( Fig. 1[] […] massive retroperitoneal hemorrhage was a complication is reported in the urologic literature.[]

  • Ganglioneuroma

    USG and CT scan showed a well-defined heterogeneous left adrenal mass with solid and cystic components. MIBG Scan revealed a left adrenal mass. S.[] (d) FDG-PET-CT: moderately hypermetabolic lesion. Zoom The MRI confirmed the minimal uptake of contrast material after administration.[] Fine needle aspiration and biopsy of pheochromocytoma has been reported to precipitate a hypertensive crisis, retroperitoneal hemorrhage and death. [4] An adrenal incidentaloma[]

  • Hemangioblastoma

    The contrast enhanced CT scan of the abdomen showed a 3.7 3.9 cm well-defined, avidly enhancing mass lesion arising from the right adrenal gland; and, another similar lesion[] Impaired glucose tolerance and hypermetabolism with weight loss are often observed.[] Fig. 7 Macroscopic finding of the resected specimen showing a right adrenal tumor with brownish solid content (a) and a retroperitoneal tumor with hemorrhage (b).[]

  • Teratoma

    Abdominal non-enhanced computed tomography (CT) scan showed a huge tumor with mixed density in right adrenal region, which had cystic components, fat, calcifications, and[] Whole-body positron emission tomography (PET) scan identified a small hypermetabolic pelvic mass.[] […] from its vascular pedicle, resulting in hemorrhage within the peritoneal cavity was described.[]

  • Retroperitoneal Disorder

    Fusion of the SPECT images with the CT scan showed co-localization of the 123I-MIBG with the retroperitoneal mass near the origin of the inferior mesenteric artery (figure[] hemorrhage.[] Severe abdominal pain may also present due to hemorrhage brought about by the death of intestinal tissues.[]
