Paravertebral crystal deposition disease: a retrospective study of clinical presentation, prevalence, and CT imaging findings.

Objectives: Paravertebral crystal deposition disease, characterized by the deposition of crystals around the vertebral bodies leading to acute inflammation and pain, is a condition that remains largely unrecognized. This study aims to elucidate the prevalence, clinical features, and CT findings associated with this disease.

Methods: We retrospectively analyzed 14,839 consecutive patients who underwent chest and/or abdominal CT (September 2017 to September 2024) owing to chest, abdominal, or back pain.

A unique case of splenic tumor exhibiting a serous carcinoma phenotype.

The spleen has no epithelial element; thus, primary carcinoma of the spleen is quite rare. We present the case of a patient with serous carcinoma of the spleen. A 76-year-old woman with no significant medical history presented with a huge lesion in the spleen.

Computed tomography findings of early-stage TAFRO syndrome and associated adrenal abnormalities.

Objectives: To compare CT findings of early (within 3 weeks post-onset)- and later (within 1 month before or after diagnostic criteria were satisfied, and later than 3 weeks post-onset) stage thrombocytopenia, anasarca, fever, reticulin fibrosis, renal dysfunction, and organomegaly (TAFRO) syndrome.

Methods: Between 2014 and 2019, 13 patients with TAFRO syndrome (8 men and 5 women; mean age, 54.9 years) from nine hospitals were enrolled.

Extraction of items identifying hiesho (cold disorder) and their utility in young males and females.

Objective: Hie (cold sensation) is one of the most common health complaints in Japan. Those who suffer from severe hie are considered as having hiesho (cold disorder). However, exact hiesho symptoms have not been defined clearly and the decision as to whether a person suffers from hiesho is subjective and based on self-awareness.

Detection of hepatocellular carcinoma by CT during arterial portography using a cone-beam CT technology: comparison with conventional CTAP.

Background: To evaluate the detectability of hepatocellular carcinoma (HCC) by computed tomography during arterial portography (CTAP) using cone-beam CT technology (CBCTAP) by comparing it with conventional CTAP.

Methods: Forty-four HCC lesions (mean diameter 1.9 +/- 1.

Rate of liver volume increase: can it predict recipient prognosis after left lobe transplantation from living related donors?

Purpose: The purpose of this study was to determine whether liver volume increase can predict recipient outcome.

Materials And Methods: Size-matched left lobe transplantation was performed for 16 patients. Computed tomography was performed in Week 1 after transplantation.

Iodized oil accumulation in the hypovascular tumor portion of early-stage hepatocellular carcinoma after ultraselective transcatheter arterial chemoembolization.

Purpose: We evaluated iodized oil accumulation in the hypovascular portion of early-stage hepatocellular carcinoma (HCC) after ultraselective transcatheter arterial embolization (TACE).

Materials And Methods: Forty-seven HCC lesions with hypovascular portions were treated by TACE at the distal level of the sub-subsegmental artery of the liver. Portal blood in the hypovascular portion was classed in two grades by computed tomography (CT) during arterial portography: decreased and preserved.

Acute cholecystitis caused by malignant cystic duct obstruction: treatment with metallic stent placement.

We report the successful management of acute cholecystitis using cystic duct stent placement in 3 patients with inoperable malignant cystic duct obstruction (2 cholangiocarcinoma and 1 pancreatic carcinoma). All patients underwent stent placement in the bile duct, using an uncovered stent in 2 and a covered stent in 1, to relieve jaundice occurring 8-184 days (mean 120 days) before the development of acute cholecystitis. The occluded cystic duct was traversed by a microcatheter and a stent was implanted 4-17 days (mean 12 days) after cholecystostomy.

Visualization of hepatic lymphatic vessels during transcatheter arterial chemoembolization for hepatocellular carcinoma.

Purpose: To analyze visualization of hepatic lymphatic vessels during transcatheter arterial chemoembolization (TACE) for hepatocellular carcinoma (HCC).

Materials And Methods: Retrospective review was conducted of 255 tumors in 161 patients treated by TACE with catheterization of the most distal portion of the tumor-feeding branches. All TACE procedures were performed with use of a mixture of iodized oil and anticancer drugs followed by gelatin sponge particles.

Ultraselective transcatheter arterial chemoembolization with a 2-f tip microcatheter for small hepatocellular carcinomas: relationship between local tumor recurrence and visualization of the portal vein with iodized oil.

Purpose: To retrospectively evaluate the relationship between local tumor recurrence and iodized oil deposition in the portal vein by using ultraselective transcatheter arterial chemoembolization (TACE) for small hepatocellular carcinoma.

Materials And Methods: One-hundred twenty-three tumors smaller than 5 cm in diameter (mean diameter, 1.9 cm; median diameter, 1.

Yamanouchi magnetic compression anastomosis for bilioenteric anastomotic stricture after living-donor liver transplantation.

Yamanouchi magnetic compression anastomosis (YMCA) is a novel interventional method that creates an anastomosis between the bile duct and small intestine. The method uses two magnets to compress the stricture transmurally, causing gradual ischemic necrosis of the stricture. This ischemic necrosis creates an anastomosis between the two magnets.
